Scatter Plots

Front

What is a scatter plot?

Back

A scatter plot 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 scatter plot 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 scatter plot indicate?

Back

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

Front

What does no correlation mean in a scatter plot?

Back

No correlation means there is no predictable relationship between the two variables; the data points do not follow any pattern.

Front

How can you identify a positive correlation in a scatter plot?

Back

A positive correlation can be identified by a pattern where points slope upwards from left to right.

Front

How can you identify a negative correlation in a scatter plot?

Back

A negative correlation can be identified by a pattern where points slope downwards from left to right.

Front

What is the purpose of a scatter plot?

Back

The purpose of a scatter plot is to visually represent the relationship between two variables and to identify any trends or correlations.

Front

What does it mean if a scatter plot has a cluster of points?

Back

A cluster of points indicates that there is a concentration of data points in that area, suggesting a possible relationship between the variables.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that lies far away from the other points in the scatter plot, which may indicate an unusual observation.

Front

What is the significance of the line of best fit in a scatter plot?

Back

The line of best fit is a straight line that best represents the data points in a scatter plot, helping to predict values and understand the relationship.
