I'm feeling good about this one. Contingency tables are definitely used to compare proportions across more than two groups, so B is for sure correct. And they're used for attribute or categorical data, so E is also right. I'll mark those two and move on.
Okay, let me think this through step-by-step. Contingency tables are used to analyze the relationship between two categorical variables, so that rules out A, C, and D. I'm pretty sure B and E are the correct answers, but I'll double-check my notes to be sure.
Hmm, I'm a bit confused on this one. I know contingency tables are used for categorical data, but I'm not sure about the specific uses. I'll have to think this through carefully.
I'm pretty confident that contingency tables are used to compare more than two sample proportions, so I'll mark B. I'm also pretty sure they're used for attribute data, so I'll mark E as well.
