What does it mean when points on a scatter plot are close together?

Back

When points on a scatter plot are close together, it indicates a strong relationship between the two variables.

Front

What does it mean when points on a scatter plot are spread out?

Back

When points on a scatter plot are spread out, it indicates a weak or no relationship between the two variables.

Front

What is the purpose of using a scatter plot?

Back

The purpose of using a scatter plot is to visually represent data and identify trends, patterns, or correlations between two variables.

Front

What is a positive correlation in a scatter plot?

Back

A positive correlation occurs when an increase in one variable leads to an increase in the other variable, resulting in an upward trend in the scatter plot.

Front

What is a negative correlation in a scatter plot?

Back

A negative correlation occurs when an increase in one variable leads to a decrease in the other variable, resulting in a downward trend in the scatter plot.

Front

What does it mean if a scatter plot has no correlation?

Back

If a scatter plot has no correlation, it means there is no discernible relationship between the two variables, and the points are scattered randomly.

Front

How can you determine the frequency of a certain value in a scatter plot?

Back

You can determine the frequency of a certain value by counting how many times that value appears in the data set represented in the scatter plot.

Front

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

Back

An example of a relationship that can be represented by a scatter plot is the relationship between the number of hours studied and test scores.

Front

What is the independent variable in a scatter plot?

Back

The independent variable is the variable that is manipulated or changed in an experiment, typically plotted on the x-axis.
