regression analysis

Regression analysis is a way of looking at data to predict what might happen in the future. It looks at a group of related things (like people's heights, ages, and weights) and then tries to figure out if one thing (like a person's weight) is related to another (like a person's height). By looking at the data, we can create a graph that shows how the two things are related to each other. We can also find out if one thing affects the other. For example, if one group of people are heavier, we can see if they are also taller than the other group.
