Consider the following pair of data sets. Which data set will have the larger ANOVA F test statistic? Why? The value of the test statistic will be larger for Data Set A because it has more spread between the means than Data Set B. The value of the test statistic will be larger for Data Set A because it has a smaller standard deviation than Data Set B.

Standard Normal Distribution Activity 1. Roll and record 100 rolls of four, fair six-sided dice. 2. Theoretically, the mean, median, and mode should all be 14. Check to see if this is the case. What is likely to happen to these values if the number of rolls were increased to 200? 300? 1000? 3. Using the calculator, find the standard deviation for the data. 4. Answer the following questions: a. What percentage of the rolls were 12,13, 14,15, or 16?...
