QUESTION 6. A researcher classifies people by age in two categories - as either under 30 or over 30. The same people are also classified by whether or not they routinely watch the evening news on television - yes or no. For the resulting data, the correct method for measuring the relationship between age and television viewing preferences would be:. ANOVA (Analysis of Variance) Pearson's Chi Square t test Pearson's Correlation
