Scatterplot Predictions

Front

What is a scatterplot?

Back

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

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 controlled.

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 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 based on the value of 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 do you interpret the slope of the line of best fit?

Back

The slope indicates the rate of change of the dependent variable for each unit change in the independent variable.

Front

What is the purpose of using a trend line in a scatterplot?

Back

The purpose of a trend line is to summarize the data and help visualize the overall direction or pattern of the data points.
