Scatter Plots Warm Up

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 association in a scatter plot indicate?

Back

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

Front

What does a negative association in a scatter plot indicate?

Back

A negative association 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 an outlier in a scatter plot?

Back

An outlier is a data point that is significantly different from other observations, often lying far away from the main cluster of points.

Front

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

Back

A strong correlation is indicated by points that are closely clustered around a straight line, either positively or negatively.

Front

What is the difference between strong and weak correlation?

Back

Strong correlation means the points are closely packed along a line, while weak correlation means the points are more spread out.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually assess the relationship between two variables and to identify trends, patterns, or outliers.

Front

What type of correlation is shown if the points slope downwards from left to right?

Back

This indicates a negative correlation.

Front

What type of correlation is shown if the points slope upwards from left to right?

Back

This indicates a positive correlation.
