# 11 Add trendline and regression equation to the plot.

11 Add trendline and regression equation to the plot. 12 The scatterplot reveals a point outside the point pattern. Copy the data to a new location in the worksheet. You now have 2 sets of data. Data that are more tha 1.5 IQR below Q1 or more than 1.5 IQR above Q3 are considered outliers and must be investigated. It was determined that the outlying point resulted from data entry error. Remove the outlier in the copy of the data. 13 Make a new scatterplot linked to the cleaned data without the outlier, and add trendline and regression equation label. 14 Compare the regression equations of the two plots. How did removal of the outlier affect the slope and R2? Reference, Question directly from week 11 homework of UMUC
