What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the function. It indicates how much the dependent variable (y) changes for a unit change in the independent variable (x).

What does a positive linear correlation indicate?

Back

A positive linear correlation indicates that as one variable increases, the other variable also increases. The graph of this relationship slopes upwards.

What does a negative linear correlation indicate?

Back

A negative linear correlation indicates that as one variable increases, the other variable decreases. The graph of this relationship slopes downwards.

How do you determine if a line is a good estimate of best fit for data?

Back

A line is a good estimate of best fit if it minimizes the distance between the line and all the data points, often assessed using the least squares method.

What is the difference between correlation and causation?

Back

Correlation indicates that two variables are related, while causation indicates that one variable directly affects the other.
