DEC. 10TH EXIT FLASHCARD: scatter plots

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional axis.

Front

What does it mean if points in a scatter plot are clustered together?

Back

It means that the points are close together, indicating a possible relationship between the two variables.

Front

What is an outlier in a scatter plot?

Back

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

Front

What does a linear relationship in a scatter plot look like?

Back

A linear relationship appears as a straight line, indicating that as one variable increases, the other variable also increases or decreases.

Front

What does it mean if a scatter plot has no correlation?

Back

It means that there is no predictable pattern between the two variables; the points are scattered randomly.

Front

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

Back

A negative correlation is identified when one variable increases while the other variable decreases, appearing as a downward slope.

Front

What are coordinates in a scatter plot?

Back

Coordinates are the ordered pairs (x, y) that represent the position of points on the scatter plot.

Front

What does the term 'independent variable' refer to in a scatter plot?

Back

The independent variable is the variable that is manipulated or changed, usually plotted on the x-axis.

Front

What does the term 'dependent variable' refer to in a scatter plot?

Back

The dependent variable is the variable that is measured or observed, usually plotted on the y-axis.

Front

How can you determine the strength of a correlation in a scatter plot?

Back

The strength of a correlation can be determined by how closely the points cluster around a line; tighter clusters indicate a stronger correlation.
