Statistics

Volume is a measure of the amount of space that a substance or object occupies. It can be calculated by multiplying the length, width, and height of an object for regular shapes, or by using mathematical formulas for irregular shapes. The units for volume are typically cubic units such as cubic meters (m^3) or cubic centimeters (cm^3).

Secondary information refers to data or knowledge that has been collected or analyzed by someone else, rather than firsthand by the individual using it. This information is usually obtained from sources such as books, journals, databases, or other published materials. It is used to support or complement primary research or analysis.

If you mean a zero with a diagonal line through it, it is the symbol for the empty set which is the set that contains nothing.

The simple answer is you cannot use statistical tests on data collected from quota samples.

Unless the sample was collected using a random sampling technique you cannot have any confidence in the results being representative of the population you are sampling. Quota samples are non random.

However this does not stop researchers from using statistical tests on quota samples, even if the results can be taken with a pinch of salt!

Most news media sources do a little research before reporting on stories that contain statistics. It is possible that they can be given false information, but their research might correct the issues of difference. The information gotten today from television and radio is pretty accurate despite differences of opinion.

Letter frequency in the English language - e t a o i n s r h l d c u m f p g w y b v k x j q z. There is a word devised to commit some of this list to memory 'Etaoin Shrdlu. There are other common lists however, in Press Reporting, in Religious writings, Scientific writing, General fiction and even on the old system of Morse Code. The first twelve letters in the above list occur in 80% of all words in the English language

There are 840 4-digit combinations without repeating any digit in the combinations.

No matter what fraction one gives, there is one closer. There is no answer to this question.

Yes, indeed it is.

because they can help you find your right answer

Oh, dude, you're hitting me with the math questions now? Okay, so the mean is like the average, which is 80. The mode is the number that appears most often, which is 66. The median is the middle number when they're all lined up, which in this case is also 78. And the range is just the difference between the highest and lowest numbers, so that's 32. Math lesson over, can we go back to talking about snacks now?

discrete

The shape of a t distribution changes with degrees of freedom (df). As the the df gets very large the shape of the t distribution will begin to look similar to that of a normal distribution. However, the t distribution has more variability than a normal distribution; especially when the df are small. When this is the case the t distribution will be flatter and more spread out than the normal distributions.

The answer is 10!/[6!*(10-6)!] where n! represents 1*2*3*...*n

Number of combinations = 10*9*8*7*6*5*4*3*2*1/(6*5*4*3*2*1*4*3*2*1)

= 10*9*8*7/(4*3*2*1) = 210

First of all place the numbers in rank order. Hence

46,57,68,72,72,93.

RANGE; is the difference between the highest and lowest numbers, which is 93-46 = 47

MEDIAN: is the absolute mid-point. Since there is no absolute mid-point, we take the two middle numbers , add them and divide by '2'. Hence. ( 68+72)/2 = 70

MODE: is the term that occurs most frequently. In this case '72'. as there are two of them , but only one each of the other terms.

MEAN; Add all the terms and divide by the number of terms.

(46+57+68+72+72+93) / 6 = 408/6 = 68

PH is a number, so it is quantitative.

dependent variable

I will rephrase your question as "What shape has only three right angles?" A shape is a 2D drawing that encloses some space. The sum of the angles must exceed 270 degrees. A rectangle is out of the question as it has four right angles. But a 5 sided shape with unequal sides (irregular pentagon) or higher number of sides is fine. I wish Wikipedia would let draw on these answers, because I could draw hundreds of shapes with three right angles. When we talk of shapes, the most regular shapes come to mind, triangles, squares, pentagons, etc. But you did not spcify that my shape had to have straight sides. Imagine, for example, a circle which I will break at three places and insert right angles. Weird, but it does have three right angles. Do the right angles have to face in towards the center? I could even draw a more bizarre shape with with three right angles facing out, connected by curved lines.

Even!!!!

Remember any number , however, large, if it ends in 0,2,4,6,8 is even.

So a number like

12345678 is even

But a number such as

87654321 is Odd., because it dies not ends in 0,2,4,6,8.

16 + 16 = 32

Or draw another way

16

16 +

32
