# Interpreting two-way tables

Two-way tables let us sort a group in two ways. For example, we see how men and women voted in the 2012 US presidential election. We can compare the percentages of men and women who voted for each candidate. Two-way tables help us understand how categories relate.

• Correct me if I'm wrong, but, if 52% of Men voted for Romney, and 43% of women did, that would make 95% as a total. Whereas, Obama only got 94%. How does that make Obama win?
• I know this comment is five years old, but this table is talking about percentages not the number of people. In this case, it would mean more females voted than males.
• I am having a hard time with interpreting two way tables. In some of the questions there are like 2 or 3 right answers to choose. i don't understand how to single out one of the choices to get the right answer. plz help.
• me too am having the same problem. Sal only discussed a little part of it and he doesn't explain it detailed since he just said percent women and percent men and then says yes to the question
• Yeah this video doesn't prepare you at all for the practice questions. The video features a simple format then the practice segment goes off the rails.
• Does relative frequency have to be a decimal or can it be a fraction? I've seen people do it different ways, but I'm not sure if that is the proper way?
• The practice problems are a lot more harder & difficult to calculate than this.
• Okay but i still don't understand the difference between the column and row relative frequency
• So men and women are columns of the table.

Obama, Romney, Other and Column Total form the rows of the table.

So basically the difference is the orientation
• I've been getting the following feedback a lot during the exercises: "We only know the column relative frequencies, not the row relative frequencies, so we cannot make this claim." Wouldn't that apply to this video as well?
