# Comparing two signals and understand if they tell a similar story

Lets say I have two datasets.
One is peoples' yes/no answer to one question.
The second is peoples' yes/no answer to an another question.
There is NO overlap between people answering the questions. I.E, each person answered one question exactly.

Now, I want to evaluate to amount of agreement/understand the relationship between the two questions. For simplicity I assume that peoples' age affect their answer(in respect to both questions) in a similar way. Based on that, I can calculate the rate of people answering yes for each age. Then I can compare this rate between the two questions and see if there is a correlation of something.

What are(if) relevant framing/methods for this type of analysis.
