Statistics
Statistics deals with collecting, organizing, and interpreting numerical data. An important aspect of statistics is the analysis of population characteristics inferred from sampling.

stem and leaf plot
Yes, I could.
-- If the sequence is significant, then there are 720 different possibilities,
and I can't list all of them here.
-- But if the sequence is not significant, then there is only one possible
6-digit group ("combination") using the digits 1, 2, 3, 4, 8, and 9.
What happens if you install a PCIe Version 1x card in a PCIe Version 2.0 slot the slot?
Witchcraft!
No, in all actuality it will work completely fine, as long as they are both indeed PCIe. You should be good to go!
dismay means noun: the feeling of despair or fear resulting from feeling of danger; using it as a verb: being unpleasantly surprised
How do you round the number 65.231 to the nearest ten thousands?
If you mean ten thousandths, it's already there.
65.231 to the nearest ten thousand rounds down to zero.
If the size of a sample equals to the size of the population?
Sample is subset of the population so sample size and population size is different.
However, as a subset can be the whole set, if the sample size equals the population size, you have sampled the entire population and you will be 100% accurate with your results; it may cost much more than surveying a [representative] sample, but you get the satisfaction of knowing for what you surveyed the population exactly.
Using a sample is a trade off between the cost of surveying the whole population and accuracy of the result.
A census is a survey of the whole population and could be considered that the sample size = population size; in this case the results are 100% accurate.
The television viewing figures are calculated using a sample of the whole population and then extrapolating them to the whole population; depending upon how the same was chosen, including its size, will affect the accuracy of the results - most likely not more than 95% accurate.
With a carefully selected (that is properly biased) sample you can prove almost anything!
In most production management systems, a "Planned" quantity and material cost is calculated based on the associated Bill of Materials (BOM) and Operatons being performed (Route) creating labor and overhead related costs. The "Actual" quantities, material costs, and labor/overhead costs are issued to a Work in Process (WIP) account and the quantities/values of the produced items are recieved from the WIP account. A variance usually occurs when there is a difference between the issued material cost plus labor and overhead and the recieved material cost of the produced item. The reasons for these variances can be differences in planned vs actual quantities, differences in system or planned cost of materials, labor, or overhead vs actual cost, or any other potential reason for an unplanned difference.
A koele is defined as a small parcel of land. The land maybe owned by one person but cultivated by another.
What are the types of variables?
THE TYPES OF VARIABLES
1.Constant or Controlling Variables
- variables that you do not change all throughout the experiment.
2.Manipulated Variable
- variable that you change in the activity.They are also called the Independent Variable
3.Responding Variable
- variable that result by changing the variable
- also called as the Dependent Variable in doing such activity ,Far Test can be achieve by changing only one variable at a time.
Why is binomial nomenclature used?
Binomial nomenclature is used to provide a standardized system of naming organisms that allows for easy identification and classification. It helps to avoid confusion that can arise from using common names that vary by region and language. Additionally, binomial nomenclature highlights the evolutionary relationships between organisms by grouping them based on shared characteristics into taxonomic categories.
The change in growth rate that results from the change in birth and death rates is known as?
natrual increas?
What is the median of the numbers 81 97 99 89 91 76?
Place the values in ascending order: 76, 81, 89, 91, 97, 99. There are 2 middle numbers; 89 & 91. The median is the mean of the 2 middle numbers; or (89+91)/2 or 90.
Why leaf arrangein whorled on a stem?
1. A form that coils or spirals; a curl or swirl: spread the icing in peaks and whorls.
2. Botany An arrangement of three or more leaves, petals, or other organs radiating from a single node.
3. Zoology A single turn or volution of a spiral shell.
4. One of the circular ridges or convolutions of a fingerprint.
5. Architecture An ornamental device, as in stonework or weaving, consisting of stylized vine leaves and tendrils.
6. A small flywheel that regulates the speed of a spinning wheel.
What is a confidence interval in statistics?
When you calculate a statistic the result is not going to be perfectly accurate because of random errors in your observations. You therefore can give the result as one value along with a confidence interval (CI) around it.
There are two interpretations of a CI. One interpretation is that you can be confident, with the stated level of confidence, that the true value of your statistic lies within the CI.
The other interpretation is that if you repeated your experiment then, for the stated percentage of cases, the statistic would lie within the CI.
