...What do you do in that case?
Still not sure honestly. I looked it up after the exam and came across an explanation that said when you have multiple numbers that can be the mode, they are both the mode. I've accepted that, but it still left me a little unsure of the answer. Put simply, the question stated:
Group A values: 1, 2, 3, 12, 12
Group B values: 1, 2, 2, 12, 12
What is the relationship between the modes of groups A and B?
Answer choices along the lines of: mode of A > B, mode of B > A, modes are equal... I think it was an A-E question, but I can't remember what the other 2 choices were.
I remember it being tough to work out logically (at the time not knowing you can have 2 modes), the highest number being the mode in B was = to the mode of A. I though oh maybe you need to average the two modes like you do if there is even number integer set and you're asked to find the median, but whatever the answer would have been if the average was taken for group B wasn't an answer choice. I'm probably missing details that would make this sound more familiar to anyone who's seen a similar question, but that's the general gist of it.
