Standard deviation II. Consider these six data values: 10, 16, 18, 20, 22, 28.
a) Find the mean and standard deviation by hand.
b) Now look at these data values: 110, 116, 118, 120,
122, 128. Without doing any calculations, explain
why the standard deviation will be the same even
though the mean is obviously different.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
