Describing and Interpreting Scatter Plots Practice

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 indicate in a scatter plot?

Back

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

Front

What does a negative correlation indicate in a scatter plot?

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 apparent relationship between the two variables; changes in one variable do not predict changes in the other.

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis that typically represents the independent variable.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.

Front

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

Back

A positive correlation is identified when the data points slope upwards from left to right.

Front

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

Back

A negative correlation is identified when the data points slope downwards from left to right.

Front

What is an example of a situation with no correlation?

Back

An example of no correlation is the relationship between the number of siblings a person has and their weight.

Front

What type of correlation would you expect between outside temperature and the number of layers of clothing worn?

Back

You would expect a negative correlation; as the temperature increases, the number of layers worn typically decreases.
