What does a positive linear association in a scatterplot indicate?

Back

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatterplot, showing the overall trend of the data points.

Front

What is the purpose of using a scatterplot?

Back

The purpose of using a scatterplot is to visually assess the relationship between two variables and identify patterns or trends.

Front

What does it mean if a scatterplot shows a nonlinear association?

Back

A nonlinear association means that the relationship between the two variables cannot be accurately represented by a straight line.

Front

How can you determine the least popular option in a survey?

Back

To determine the least popular option, compare the frequencies or percentages of each option and identify the one with the lowest value.
