What is the relationship between miles driven and the amount of gas remaining in the tank?

Back

As the number of miles driven increases, the amount of gas remaining in the tank decreases.

Front

What type of graph is used to show the relationship between two quantitative variables?

Back

A scatter plot.

Front

What does a scatter plot represent?

Back

A scatter plot represents the relationship between two variables by displaying data points on a two-dimensional graph.

Front

What does a negative correlation in a scatter plot indicate?

Back

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

Front

What is a positive correlation in a scatter plot?

Back

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

Front

What is the purpose of using scatter plots in data analysis?

Back

Scatter plots are used to visually assess the relationship between two variables.

Front

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

Back

It means that there is no discernible relationship between the two variables.

Front

How can you determine the strength of a correlation in a scatter plot?

Back

The strength of a correlation can be determined by how closely the data points cluster around a line of best fit.

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 scatter plot.

Front

What is the independent variable in a relationship between miles driven and gas remaining?

Back

Miles driven is the independent variable.
