Chapter 4 Displaying and Summarizing Quantitative Data
... 2) if the shape is skewed, report the median and IQR; the mean and standard deviation are sensitive to outliers (you can include the mean and standard deviation, but you should point out why the mean and median differ) 3) if the shape is symmetric, report the mean and standard deviation. 4) if there ...

Two-Group Parametric Hypothesis Testing
... This test is appropriate whenever data have been collected in a way that results in the two samples of scores being related to each other. Suppose that Farmer Sol is evaluating the yield of two varieties of cucumbers that produce superior fruits, the SuperCuke and the Cukazilla. He has 12 small plot ...
