Scatter Plots Refresher

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two data sets, with one variable plotted along the x-axis and the other along the y-axis.

Front

What does a positive correlation indicate in a scatter plot?

Back

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

Front

What does a negative correlation indicate in a scatter plot?

Back

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

Front

What is no correlation in a scatter plot?

Back

No correlation means that there is no discernible relationship between the two variables; changes in one variable do not predict changes in the other.

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 does the slope of a scatter plot represent?

Back

The slope of a scatter plot represents the direction and strength of the relationship between the two variables.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that differ significantly from other observations; they can affect the correlation and overall interpretation of the data.

Front

What type of correlation is represented if the points in a scatter plot are randomly scattered?

Back

Randomly scattered points indicate no correlation between the variables.

Front

In a scatter plot, what does a steep slope indicate?

Back

A steep slope indicates a strong relationship between the two variables, whether positive or negative.
