Scatterplot Predictions

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

What does the x-axis represent in a scatterplot?

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 scatterplot?

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 scatterplot, 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 the line of best fit?

Back

The purpose of the line of best fit is to make predictions about the dependent variable based on the independent variable.

Front

What does a positive correlation in a scatterplot indicate?

Back

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

Front

What does a negative correlation in a scatterplot indicate?

Back

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

Front

What does no correlation in a scatterplot indicate?

Back

No correlation indicates that there is no apparent relationship between the two variables.

Front

How can you use a scatterplot to make predictions?

Back

You can use the line of best fit to estimate the value of the dependent variable for a given value of the independent variable.
