For example, we might not be interested in the average height of people studying statistics, but rather the . of people above or below a certain height. Although this question is slightly different from one th

One sample non-parametric teststion is a specific value and then determine the likelihood of drawing from this population a sample with a different mean or proportion. We do this by calculating a .-score or a .-score and looking up the corresponding probability in the appropriate table. If the difference between the sample statis

Measures of central tendency and measures of dispersionan exam is 65, and that all the scores lie between a minimum of 24 and a maximum of 87. The first of these numbers (65) — which represents the ‘average’ or ‘typical’ score — is called a .. The second set — which indicates the spread of cases across the values of the variable — is called a ..

The ,-test for a single proportionat investigates the mean of a distribution, the procedures for making an inference are basically the same. We will still conduct a .-test, but this time based on a sample proportion rather than a sample mean.
