Question

Before data is entered into the regression calculator, some data may be excluded. Explain why the data pair (0, 100) was excluded for the comparison of hours slept the night before and the test score. Describe what this data point represents. If it was included, would the trend line describe the data well?

Answer 1

Outliers should be excluded when producing a trend line, regardless of the method used. The student got a score of 100 with no sleep. This data pair was a rare event. If the outlier was included, it would cause the trend line to misrepresent the typical data relationship.
