Scatter plots are important tools for showing how different things are related in statistics.
Here’s why they are useful:
Finding Relationships: Scatter plots help you see what kind of relationship two things have. Is it straight (linear), curved (non-linear), or is there no connection at all?
Correlation Coefficient: This is a number between -1 and 1. It tells you how strong the relationship is and in what direction it goes.
Least Squares Method: This technique is used in a type of math called linear regression. It helps find the best line that fits the data by making small errors as small as possible. This is helpful to make predictions.
When you understand scatter plots, it makes it easier to look at data and test ideas in Year 13 math.
