What would be the most appropriate procedure to use to analyze data to answer this question? Only choose a test that handles multiple comparisons if such a test is needed. O ANOVA (Analysis of Variance) O Regression Test of Slope or Correlation O Test for a Difference of Proportions O Chi-square test of association O Test for a Difference of Means
One-way or two-way refers to the number of independent variables (IV's) in your Analysis of Variance test. One-way has one independent variable (either discrete or continuous) and two-way has two independent variables (either discrete or continuous). For example, a one-way Analysis of Variance could have one IV (brand of cereal) and a two-way Analysis of Variance has two IV's (brand of cereal, calories). O True O False
