Create one symmetrical (normal) and one asymmetrical set of data, and explain why each fit the definition. Knowing the type of distribution and the skewness of the data, is it possible to draw conclusions about the mean and the median?

Why would it be best to use particular measures of center and spread if the data is symmetrical or asymmetrical?

What measures would you use in each case?

Tim's phone service charges $23.06 plus an additional $0.22 for each text message sent per month. if tim's phone bill was $28.56, which equation could be used to find how many text messages, x, tim sent last month?

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.
