1. What is regression analysis?Regression analysis is a math tool that helps us see how one thing changes when another thing changes. It lets us predict outcomes by looking at patterns in data.
2. How does regression help us guess plant height?By drawing a line that best fits the data, we can predict how tall a plant will grow when we know how much water it gets. The line shows the average change in height for each unit of water.

Dependent Variable: The variable whose variation is to be explained or predicted in a statistical model.
Independent Variable: A variable that is manipulated or changed to observe its effect on the dependent variable.
Regression Coefficient: A numerical value that quantifies the relationship between an independent variable and the dependent variable.
