Scatterplot and Variables Review

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional grid.

Front

What does the x-axis represent in a scatter plot?

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or changed.

Front

What does the y-axis represent in a scatter plot?

Back

The y-axis typically represents the dependent variable, which is the variable that is measured or observed.

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, used to make predictions.

Front

How do you determine the line of best fit?

Back

The line of best fit is determined by minimizing the distance between the line and all the data points.

Front

What is the purpose of using a line of best fit?

Back

The purpose is to make predictions about the dependent variable based on the independent variable.

Front

What is an independent variable?

Back

An independent variable is the one factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

A dependent variable is the factor that is measured in an experiment and is affected by changes in the independent variable.

Front

What does it mean to estimate from a scatter plot?

Back

Estimating from a scatter plot means using the visual data to make an educated guess about a value that is not explicitly stated.

Front

What is correlation in a scatter plot?

Back

Correlation refers to the relationship between two variables, which can be positive, negative, or none.
