Scatter Plots Review

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 the line of best fit represent in a scatter plot?

Back

The line of best fit represents the trend of the data points in a scatter plot, indicating the general direction of the relationship between the variables.

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a linear relationship between two variables, which can be strong, weak, positive, or negative.

Front

What is a strong correlation?

Back

A strong correlation indicates that the data points are closely clustered around the line of best fit, suggesting a clear relationship between the variables.

Front

What is a weak correlation?

Back

A weak correlation indicates that the data points are more spread out and do not closely follow the line of best fit, suggesting a less clear relationship.

Front

What is the difference between linear and non-linear relationships?

Back

A linear relationship can be represented by a straight line, while a non-linear relationship cannot be represented by a straight line and may curve or change direction.

Front

What does a positive slope indicate in a scatter plot?

Back

A positive slope indicates that as one variable increases, the other variable also increases, showing a direct relationship.

Front

What does a negative slope indicate in a scatter plot?

Back

A negative slope indicates that as one variable increases, the other variable decreases, showing an inverse relationship.
