Scatter Plots and Correlations

Front

What is a scatter plot?

Back

A scatter plot is a type of graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

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 predictable relationship between the two variables; the points do not show any pattern.

Front

What is a linear association in a scatter plot?

Back

A linear association means that the points in the scatter plot can be approximated by a straight line.

Front

What is a nonlinear association in a scatter plot?

Back

A nonlinear association means that the relationship between the variables cannot be represented by a straight line.

Front

What is a strong correlation?

Back

A strong correlation means that the points in the scatter plot are closely clustered around a line, indicating a strong relationship between the variables.

Front

What is a weak correlation?

Back

A weak correlation means that the points in the scatter plot are more spread out, indicating a weaker relationship between the variables.

Front

How can you identify a positive linear association in a scatter plot?

Back

A positive linear association can be identified when the points slope upwards from left to right.

Front

How can you identify a negative linear association in a scatter plot?

Back

A negative linear association can be identified when the points slope downwards from left to right.
