Chapter 12: Q. 54 (page 719)

54. Are you more or less confident in the predictive ability of the new line of best fit?

Short Answer

Expert verified

In comparison to the preceding equation with an outlier, the researcher can now be more sure of the prediction's accuracy

Step by step solution

01

Concept introduction

A possible outlier remains a data point that varies immensely from the rest of the data.

02

Explanation

If any data contains a potential outlier, that prospective outlier will flatten the slope of the line of best fit since the outlier is located apart from the other data points. As a result, the line of best fit will become less accurate as a result of the probable outlier.

In comparison to the preceding equation with an outlier, the researcher can now be more sure of the prediction's accuracy
