What does a trend line in a scatter plot represent?

Back

A trend line is a straight line that best represents the data points in a scatter plot, indicating the general direction of the relationship between the variables.

Front

What does a positive association in a scatter plot indicate?

Back

A positive association indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative association in a scatter plot indicate?

Back

A negative association indicates that as one variable increases, the other variable tends to decrease.

How can you determine the line of best fit in a scatter plot?

Back

The line of best fit can be determined by visually assessing the scatter plot and drawing a line that minimizes the distance between the line and all data points.

Front

What is the purpose of using a scatter plot?

Back

The purpose of using a scatter plot is to visually represent the relationship between two variables and to identify any trends or correlations.

Front

What does it mean if the points in a scatter plot are widely spread out?

Back

If the points are widely spread out, it indicates a weak correlation between the two variables.

Front

What does it mean if the points in a scatter plot are closely clustered together?

Back

If the points are closely clustered together, it indicates a strong correlation between the two variables.

Front

How can you use a scatter plot to make predictions?

Back

You can use a scatter plot to make predictions by extending the trend line to estimate the value of one variable based on the value of the other.

Front

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation indicates that one variable directly affects the other.
