- An outlier can reduce the accuracy of a linear model. True FalseIndependent variable data is listed in cells B2 through B100, and dependent variable data is in cells C2 through C100. Which spreadsheet function would calculate the slope of a linear regression model of this data? Group of answer choices =SLOPE(B2:B100,C2:C100) =SLOPE(C2:C100,B2:B100) =SLOPE(B2,C2) =SLOPE(C2,C100,B2,B100)Explore non-linear regression. Determine a possible data setthat would most likely not have a linear relationship, but would have a non-linear relationship. Discuss the type of data (find and present an actual example) and the relationship that the data would have. Also discuss why you think it would have this type of relationship.
