Back

A scatter plot is a graph that shows the relationship of two data sets.

Front

What does the slope of a line represent in a scatter plot?

Back

The slope of a line represents the rate of change between the two variables in the scatter plot.

Front

What is the equation of a line of best fit?

Back

The equation of a line of best fit is a linear equation that best represents the data points in a scatter plot.

Front

What does a positive slope indicate in a scatter plot?

Back

A positive slope indicates that as one variable increases, the other variable also increases.

Front

What does a negative slope indicate in a scatter plot?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

Front

What is the purpose of a line of best fit?

Back

The purpose of a line of best fit is to summarize the relationship between the variables and make predictions.

Front

How can you determine if a scatter plot shows a linear relationship?

Back

A scatter plot shows a linear relationship if the data points roughly form a straight line.

Front

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

Back

The y-intercept is the value of y when x is zero, indicating the starting point of the relationship.

Front

What does it mean if there is no line of best fit for a scatter plot?

Back

It means that there is no clear linear relationship between the variables.

Front

What is an example of a situation that can be represented by a scatter plot?

Back

The relationship between the number of hours studied and test scores.
