Compass error refers to a magnetic compasses natural tendencies to produce erroneous readings in certain circumstances. Sometimes this may be due to environmental effects such as proximity to a strong magnetic field. Compass error is also frequently the result of shortcomings or anomalies in the way compasses work.
Compass error due to environmental effects usually refers to an airplanes compass being drawn toward the magnetic fields generated by the aircrafts engines. This is called magnetic deviation. Additionally in some regions with high concentrations of iron in the soil, compasses may give all sorts of erroneous information.
Magnetic compass "variation" deals with the difference between the magnetic north pole (which magnetic compasses point to) and the true north pole (the actual geographical north pole.) While this difference may seem minor, magnetic variation can mean a difference of up to 4 or 5 degrees in some places.
In aviation, compasses may also give erroneous readings when turning or performing other maneuvers. This is due to the curvature of the earth combined with the fact that the compass needle wishes to point at the magnetic north pole. Since the earth is round, and the compass points to the magnetic north pole, the compass needle will in most cases be drawn to a point below the horizon from the users standpoint. This will cause the magnetic compass to precede when turning to a northern heading, and to lag when turning to a southern heading.
What is Chile's life expectancy rate?
total population: 76.58 years male: 73.3 years female: 80.03 years (2005 est.)
What are advantages of primary data?
The main advantage of primary data is that it provides accurate information. Because primary data is information that is collected at the time of an event, ie from firsthand experience, it can provide [in a historical context] information about social standards at the time, common biases of the time, and overall, a more insightful look at a given event.
What are the statistics on Narcissists and marriage and divorce?
Unfortunately you will never get correct stats on this. The label "Narcissist" is used too widely and a person could simply be ego-tripping, a perfectionist or a perfect poop, but not necessarily a narcissist. It would take a therapist to label such a person and many people never feel the need to seek out psychological counseling so true stats will never be on this one. this is a deep question. we will never know the answer to that. So many victims cannot speak up and so many abusors, Ns or not fail to seek help. IT does seem pervasive by what i HAVE read on clinical studies that N's seem to DEPEND on having a long term "mate" around with which to feed off. Not a true marriage as in love honor cherish etc. Well, just read some of the posts and better yet articles of actual diagnoses.
What are opinions on how to pick winning lottery numbers?
There is no way to pick lottery numbers, at least not one to increases your chances of winning. Just save time by letting the machine choose your numbers for you. Better yet, save your money and don't play at all. If you really feel that you need to wager, go to the race track and learn how to handicap. At least at the track you can use your intellect to make good bets and avoid the bad ones. (A horse that has a 50-50 chance of winning a race but is paying 6 to 5, for example, or 3 to 2 is a good wager.)
Period extending from Dec. 24 to Jan. 6
Yuletide is a feast or holiday celebrated by the historical Germanic people.
You will sometimes see the prefix -tide, meaning a period of time, used in a few other words, although its use is considered obsolete: Eastertide, Chistmastide, eventide (evening time).
What are the advantages and disadvantages of moving average method?
Moving average is best used when checking out your weight on a daily basis. Simply calculate the average on an everyday basis to find out the fittest or the fattest of you. We were also trying to find answers to this very question and fyi my name is A payam
What is the binomial nomenclature of a coyote?
Canis latrans is the binomial nomenclature of a coyote.
In a criterion-referenced test, percentages are calculated based on mastery of specific content or skills against a predetermined standard or criteria. On the other hand, percentiles in a norm-referenced test indicate a test taker's rank compared to a specific group of test takers, showing the percentage of scores that are equal to or below a particular score.
What is the meaning of mean percentage score?
The mean percentage score is the average percentage obtained by a group of individuals on a particular test, assessment, or activity. It provides a measure of central tendency for the performance of the group, indicating the typical percentage achieved.
Ther are lots of numbers between 2 and 3 here are just some of them:
2.1,2.2,2.3,2.4,2.5,2.6,2.7,2.8,2.9 etc.
What letter grade is 34 over 50?
You can find the percentage by dividing 50 (the total) by the number you received (34).
That's a 68 percent. If your teacher grades on a curve, that could be anything from a D- to an A; on a strict percentage scale, it would normally be a D or D+ though a very lenient teacher might regard it as a C-.
What is binary logistic regression?
Binary logistic regression is a logistic regression that applies to binary (0,1) variables (e.g. live or die, fail or pass...). Binary logistic regression is used to predict and model 0,1 problems in medicine, BI and many more fields. The reason logistic regression is preferred by many researchers is that it allows one to see the effect every variable has on the model in contrast to black boxed models such as neural networks.
Is IQ scale ordinal or interval?
The IQ scale is considered interval because the differences between scores are standardized and consistent across the range of scores. This means that a difference of 10 points on the IQ scale represents the same change in intelligence level regardless of where on the scale it occurs.
What are the Computational Techniques in Educational Planning?
Computational techniques in educational planning involve using algorithms and mathematical models to analyze data, predict outcomes, and optimize decisions related to education. These techniques can include machine learning algorithms for student performance prediction, optimization algorithms for scheduling classes and resources, and data mining techniques for identifying patterns in student behavior. By leveraging computational tools, educational planners can make data-driven decisions to improve educational outcomes and resource allocation.
What is the general rule for the mystic rose?
The general rule for the mystic rose practice is to engage in three weeks of laughter for one hour each day, followed by three weeks of weeping for one hour each day, and finally three weeks of silence for one hour each day. This practice is meant to help release repressed emotions and connect more deeply with one's inner self.
What are the Inoculation Techniques?
Inoculation techniques involve introducing a small amount of a specific substance, like a vaccine or a microorganism, into a living organism to stimulate an immune response or induce resistance to a particular disease. Common methods include injection, ingestion, inhalation, and topical application. These techniques are crucial in preventing diseases and developing immunity in individuals.
How do you make normal distribution curve in Excel?
In An Introduction to Excel's Normal Distribution Functions I presented several figures like the one below. This article explains how to create these figures in Excel.
Even if you have no particular reason to chart a normal curve, you might find the techniques interesting. This is because you might need to use similar techniques when you create other charts.
One general technique that I used in this workbook was to set up two worksheets, a Control worksheet and a Data worksheet.
Let's address each of these separately.
First, however, you might wonder how Excel could produce the colors used for this figure. This link explains how to get the free workbook that uses these colors and the free workbook that I explain how to create below.
Set Up the Control WorksheetIn general, you create a normal curve just as you create any other chart in Excel: You set up the data and then chart it.To set up the data, open a new workbook with at least two worksheets. Name one of these Control and the other Data.
In the Control worksheet, first set up the area shown here.
After you enter the labels in column A, assign them as range names in column B. To do so, select the range A2:B8 and choose Insert, Name, Create. Ensure that only Left Column is checked, then choose OK. Do the same for the range A11:B14.
The numbers in the Settings section are values; enter them as shown. Here's a short explanation of each:
Mean. The average value of your data.
StdDev. The Standard Deviation of your data.
NumRows. The number of rows of data to be plotted.
Zmin. The smallest standard deviation to be plotted.
Zmax. The largest standard deviation to be plotted.
PctClear. The percentage of the unshaded area from the left side of the curve, from .0001% to 99.999%.
PctShade. The percentage of the shaded area from the left side of the curve, from .0001% to 99.999%.
The numbers in the Calculations section are returned by formulas:
ShadeLeft =NORMSINV(PctClear)*StdDev+Mean
NORMSINV is the inverse of NORMSDIST function. Given the probability that a variable is within a certain distance of the mean, it finds the z value...the number of standard deviations. To calculate the extent of the shade at its left side, we multiply the NORMSINV result by the amount of the standard deviation, then add the mean.
ShadeRight =NORMSINV(PctShade)*StdDev+Mean
We use the same logic with the PctShade area as for the PctClear area. By doing so, we define the right side of the shaded area.
CurveMin =Zmin*StdDev+Mean
This formula defines the left side of the curve.
CurveMax =Zmax*StdDev+Mean
This formula defines the right side of the curve.
Set Up the Data SheetThis figure shows the top of the Data sheet. Let's take each of these columns in turn:The Sequence value in column A is a counter, from 1 to the number of rows of data. The counter is for convenience only; it's not used in the formulas. In this example, I used 100 rows.
Enter 1 in cell A2, then select the column from cell A2 through the bottom of your spreadsheet. To do so, hold down Ctrl and Shift; and press the Down arrow key. To enter the values, choose Edit, Insert, Series; enter 100 as the stop value in the Series dialog; then choose OK.
Column B returns the Z values from the lowest value to the highest value:
B2: =Zmin
B3: =(Zmax-Zmin)/(NumRows-1)+B2
Column C calculates the chart's X value for each Z value:
C2: =B2*StdDev+Mean
Column D calculates the chart's Y value:
D2: =NORMDIST(C2,Mean,StdDev,FALSE)
Column E calculates the Y values for the area to be shaded:
E2: =IF(C2>ShadeRight,NA(),IF(C2 Copy cell B3 and the formulas in the range C2:E2 down their columns to the last sequence number, in row 101. To complete this step, assign the labels in row 1 of the Data sheet to the data beneath those labels. To do so, first select the range A1:E101. Choose Insert, Name, Create. In the Create Names dialog, make sure only Top Row is checked; then choose OK. To set up the chart of the normal curve, select the range C2:D101. Choose Insert, Chart, or click the Chart Wizard icon. Under Chart Type, choose XY (Scatter). Under Chart Sub-Type, choose "Scatter with data points connected by smooth Lines without markers." Then choose Finish. If you click on the curve, your formula should look something like this: =SERIES(,Data!$C$2:$C$101,Data!$D$2:$D$101,1) You'll find this formula easier work with if you convert its cell references to range names. To do so, edit the formula to: =SERIES(,NormalCurve.xls!X,NormalCurve.xls!Y,1) Here, NormalCurve.xls is the name of my workbook. Your SERIES formula could have a different name. At this point, your chart should look something like the one shown here. To set up the data series for the shaded area beneath the curve, it's easiest to copy the first data series and then modify it. To copy the data series, first select the curve in the chart. Then select the SERIES formula in the formula bar. Copy this formula by pressing Ctrl+C. Then press Esc to de-select the formula. To paste the data series, first click anywhere on the edge of the chart object. After you do so, the SERIES formula will disappear and the words "Chart Area" will appear at the far left side of your formula bar. To paste the formula, click in the formula bar area and then press Ctrl+V. After you paste the SERIES formula, your chart will look something like this. At this point, the chart displays two identical data series, Series 1 and Series 2. Because we want the curve to be shown on top of the shaded area, we'll modify Series 1 to display the shading, and we'll leave Series 2 undisturbed. To select Series 1, first click on the curve. Then look in your formula bar to see which series you've selected. If you see Series 2, press your Down Arrow key once to select Series 1. With Series 1 displayed in your formula bar, change the formula so that it looks like one of these two versions: =SERIES(,Data!$C$2:$C$101,Data!$E$2:$E$101,1) =SERIES(,NormalCurve.xls!X,NormalCurve.xls!Area,1) You'll use the second version if you have assigned range names as I suggested above. At this point, your chart will look the same as it did before. It's now time to change that condition. With Series 1 selected, choose Format, Selected Data Series. In the Y Error Bars tab, choose to display the Minus version of the error bar, and set the Error Amount to a Percentage value of 100%. Then press OK. Here's your initial result. It doesn't look very good, but at least we're heading in the right direction. We next need to change the format the error bars in two ways. We need to make them thicker, which will eliminate the banding in the shaded area, and we typically will change the color of the shaded area. To format the error bars, first click on the error-bar area in your chart. Choose Format, Selected Error Bars. In the Patterns tab, modify the Line settings. Set its color to any color you prefer. And set the line's weight to its thickest setting. Then choose OK. After you make these changes, your chart should look something like this. Now all you need to do is to clean up the chart slightly. To eliminate the legend at the right, select the Legend object within the Chart Area, and then press Delete. To remove the shading in the Plot Area, first select the Plot Area. Choose Format, Selected Plot Area and set the Area shading to None. Then choose OK. Your chart now will look like this. If you want to format the chart so that it looks more like the figure at the beginning of this article, you need to take several additional steps. First, you assign a color patter to the Chart Area, and remove its border. To do so, select the Chart Area. Choose Format, Selected Chart Area, in the Patterns tab choose a color for the Area and choose None for both the Border. If you want to remove the gridlines, select the chart. Choose Chart, Chart Options. In the Gridlines tab, deselect all axes. Then choose OK. If you want to remove the border, select the Plot Area. Choose Border, Selected Plot Area. Set the Border pattern to None, then choose OK. Finally, to assign a number format to the Y axis, first select the axis. Then choose Format, Selected Axis. In the Number tab choose the Custom category and type in this number format: #,###.00. Then choose OK. Your chart should look something like the one shown here. Now, you merely need to adjust its size as needed. As I mentioned at the beginning of this article, use this link to download a free copy of the workbook described here.
What do scientists often do to reduce the effects of uncontrollable variables?
Scientists often use control groups, randomization, and blinding techniques to reduce the effects of uncontrollable variables in their experiments. Control groups help establish a baseline for comparison, randomization helps minimize bias, and blinding techniques prevent researchers and participants from being influenced by their expectations.
Political statistics are numerical data and analysis related to political topics, such as elections, public opinion, government policies, and decision-making processes. They help researchers, policymakers, and the public understand trends, patterns, and outcomes in the political sphere.
How is democracy an abuse of statistics?
Democracy is not an abuse of statistics. Rather, statistics can be used in democratic processes to inform decision-making, policy formulation, and public understanding. When used appropriately, statistics can help ensure that decisions are based on evidence and contribute to a more informed and participatory democracy.
What are the odds that you will die before the age of 50?
In the U.S., 4.5% of women and 8% of men die before the age of 50. (This information is taken directly from actuarial Death Rate statistics compiled in 2006).
How do you write a cover letter for caregiver?
When writing a cover letter for a caregiver position, start by introducing yourself and explaining your relevant experience in a compassionate and attentive manner. Highlight specific skills such as patient care, medication management, and communication. Conclude by expressing your passion for providing care and your interest in contributing to the well-being of those in need.
Most of us would like to think so.
It depends on your outlook on life; your perspective. An Existentialist would say "no, but you have to live like there is anyway" an Nihilist would say "no." A Christian would say "yes, God has a plan for everyone", while an atheist would probably say "let me eat your baby!" Lol, jk, they would probably say "it depends, most of us would like to think so."
