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 axis.

Front

What does a positive correlation in a scatterplot indicate?

Back

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

Front

What does a negative correlation in a scatterplot indicate?

Back

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

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatterplot, showing the trend of the data.

Front

How do you determine the slope of a line in a scatterplot?

Back

The slope is determined by the change in the y-values divided by the change in the x-values between two points on the line.

Front

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

Back

No correlation means that there is no apparent relationship between the two variables; the data points do not follow a clear pattern.

Front

What is a cluster in a scatterplot?

Back

A cluster is a group of points that are close together in a scatterplot, indicating a concentration of data.

Front

What does the x-axis typically 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 typically represent in a scatterplot?

Back

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

Front

How can you identify outliers in a scatterplot?

Back

Outliers are points that are far away from the main cluster of data points and do not fit the overall pattern.
