An outlier is a data point that differs significantly from other observations, often appearing far away from the trend of the data.

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

Back

A positive linear association can be identified by a pattern where 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 by a pattern where points slope downwards from left to right.

Front

What is the purpose of a trend line in a scatter plot?

Back

A trend line is used to summarize the relationship between the variables and to predict future values.

Front

What does it mean if a scatter plot has a strong association?

Back

A strong association means that the data points are closely clustered around a line or curve, indicating a clear relationship.

Front

What does it mean if a scatter plot has a weak association?

Back

A weak association means that the data points are more spread out and do not follow a clear pattern.
