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. The value of the test statistic will be larger for Data Set B because it has...
