How do you determine the equation of the line of best fit?

Back

The equation of the line of best fit can be determined using statistical methods such as linear regression.

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or none.

Front

What is the purpose of the line of best fit?

Back

The purpose of the line of best fit is to make predictions about one variable based on the value of another variable.

What is the formula for a linear equation?

Back

The formula for a linear equation is typically written as y = mx + b, where m is the slope and b is the y-intercept.
