Line of Best Fit Flashcard

Front

What is a line of best fit used for?

Back

To make predictions.

Front

Which line represents the line of best fit for a scatter plot?

Back

The line that best represents the trend of the data points.

Front

What is the equation of the line of best fit?

Back

An equation that describes the relationship between two variables in a scatter plot.

Front

What does the slope of a line of best fit indicate?

Back

The rate of change of the dependent variable with respect to the independent variable.

Front

What does a positive slope in a line of best fit indicate?

Back

As the independent variable increases, the dependent variable also increases.

Front

What does a negative slope in a line of best fit indicate?

Back

As the independent variable increases, the dependent variable decreases.

Front

What is the y-intercept in the equation of a line of best fit?

Back

The value of the dependent variable when the independent variable is zero.

Front

How do you determine the line of best fit from a scatter plot?

Back

By visually assessing the trend of the data points and drawing a line that minimizes the distance to all points.

Front

What is correlation in the context of a scatter plot?

Back

A measure of the strength and direction of the relationship between two variables.

Front

What does it mean if there is no correlation in a scatter plot?

Back

There is no discernible relationship between the two variables.
