Explain what it means to have a correlation in a scatterplot.

Answer:

A correlation in a scatterplot means there is a visible relationship or trend between the two variables. As the input (x-axis) increases, the output (y-axis) tends to follow a specific pattern. For example, if the outputs generally increase, there is a positive correlation, and if they generally decrease, there is a negative correlation.
