CHAPTER 8 BIVARIATE STATISTICAL ANALYSES WITH CONTINUOUS VARIABLES HOMEWORK ASSIGNMENT TWO: NORMAL OR NOT NORMAL? For each of the following sets of univariate statistics for independent (IV) and dependent (DV) con- tinuous variables, examine the mean, median, and mode. Would you want to interpret a Pearson correlation or a Spearman's correlation (Por S)? If skewed, which direction is the distribution skewed for each variable? 100 APPLIED ANALYTICAL METHIDS: SURVIVAL GUIDE (Continued) SKEWED MODE 40 46 MEDIAN P OR S?LOR R VARIABLES DV: Years to retirement IV: Ice cream consumption (gal/per MEAN 40 59 31 0 100 100 DV: Number of homicides (per I(00 K) IV: Commuting (minutes/day) DV: Sleep (hours/night) IV: Length of movie (minutes) DV: Bags of popcorn (consumed/movieicustomer) IV: Swimming laps in pool (lans/week) DV: Weight loss (Ih/weck) 23 7.5 105 8.5 90 98 120 122 3.2 EXTRA CREDIT! Which one of these, if any, looks to be improbable? Look closely at the way each variable is being measured and the univariate statistics. This is an opportunity to use your critical thinking skills and not assume that these statistics are somewhat accurate, even if they are fictitious Make sure to include an explanation as to why the statistics seem to be off.

Explanation / Answer

Number of homicides seems to be improbable
