and are the population proportions for X's and Y's, respectively. m and n are the large sample sizes for X's and Y's, respectively. The estimator for p is .

s1 = population standard deviation estimate of sample 1. s2 = population standard deviation estimate of sample 2. n1 = number of cases in sample 1. ... In the formula, there should be a sum operator in front of the (Y-Yp). For unknown reason, it cannot show up here. 1

The text refers to this as "s2," and "sample variance." But note that this is not the variance of the sample. It is called sample variance because it was calculated from the sample. ESTIMATE OF POPULATION STANDARD DEVIATION. 7 The sample standard deviation is a biased estimator of the. population standard deviation.

Those deviations squared are {4, 4} the average of which (the variance) is 4. Therefore, the standard deviation is 2. In this case 100% of the values in the population are at one standard deviation of the mean. The standard deviation is the most common measure of statistical dispersion, measuring how widely spread the values in a data set are.

The value of the population standard deviation ( may not be known. Instead, the value of the sample standard deviation s may be known. If n is sufficiently large (n>40), 100(1-()% large sample confidence interval for ( is where . Example 4:

We define the deviation of a single score as its distance from the mean: Variance. is symbolized by ( 2. Standard Deviation. is (. N is the number of scores. However, when the data of a sample are used to estimate the variance of the population from which the sample was drawn, the population variance estimate is computed instead:
