Question

A market researcher is studying the spending habits of people across age groups. The amount of money spent by each individual is classified by spending category (Dining out, Shopping, or Electronics) and generation (Gen-X, Gen-Y, Gen-Z, or Baby Boomers). The data and an incomplete ANOVA table are shown below.   For the analysis with an interaction between spending category and generation, the first hypothesis test to conduct should be about ________.
A) the average spending across spending 
B) the interaction between spending and generation 
C) the average spending across generation 
D) both the average spending across spending and generation

Quizplus · Accepted Answer

The first hypothesis test to conduct should be about the interaction between spending category and generation, as the research is specifically studying the different spending habits across age groups and spending categories. It is important to determine if there is a significant interaction between these two variables before proceeding with any further analysis. The other options (A, C, and D) are not as relevant to the research question at hand.
