Introduction to Scatter Plots

When looking at a scatter plot, there are three types of association:

• linear, nonlinear, no
• positive, negative, no
• linear, circular, no
• up, down, no

As the independent variable increases, the dependent variable decreases

• positive correlation
• negative correlation
• no correlation

A data point that is far away from other points and doesn't fit the general pattern is...

• a single point
• an outlaw
• forgotten data
• an outlier

A scatter plot is...

• A linear equation
• A graph with dots all over it
• A graph of numerical data on two variables
• A representation of categorical data

What type of association or correlation does the scatter plot represent?

• positive
• negative
• no

No correlation or association is when...

• there is a nonlinear trend.
• the data is not close together.
• there is no relationship between the data.
• there is a negative linear trend.

When points in the scatter plot appear to form two or more distinct clouds of points, it's called...

• clusters
• bunches
• groups
• cliques

When the scatter plot shows an increase in the outputs as the inputs are increasing

• positive correlation
• negative correlation
• no correlation

What pattern do you see in the data?

• positive correlation
• negative correlation
• no correlation

What kind of relationship does this scatter plot represent?

• positive, linear
• negative, linear
• negative, nonlinear
• no relationship
