In describing a dataset, what does the standard deviation or standard error represent?

The standard deviation is a statistic that lets you know how tightly all the subjects are clustered around the mean in a set of data. A single standard deviation away from the mean in either of the directions accounts for somewhere around 68 % of data. If two standard deviations are away from the mean, it accounts for around 95% of data. If three standard deviations are away it accounts for 99% of the data.

1) The total range of variation in the dataset is called RANGE.

3) A measure of the variation around the estimate of the mean is SEM (STANDARD ERROR OF THE MEAN).

4) The most common value observed (highest frequency) is MODE.

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female
