Solution
In Excel's Trendline tool, the value of the ________ gives the measure of fit of the line to the data.
To find the answer, we need to understand what each of the answer choices represents in the context of a trendline in Excel.
-
Linear function: A linear function represents a straight line relationship between two variables. While it is related to the measure of fit, it does not directly provide the value we are looking for.
-
R-squared: R-squared, also known as the coefficient of determination, is a statistical measure that represents the proportion of the variance in the dependent variable that can be explained by the independent variable(s). It is commonly used to assess the goodness of fit of a regression model, including trendlines. Therefore, R-squared is the correct answer choice.
-
Moving average: Moving average is a statistical technique used to analyze data points by creating a series of averages of different subsets of the full data set. While it can be used to smooth out fluctuations in data, it does not directly provide the measure of fit of a trendline.
-
Set intercept: Setting the intercept refers to specifying a fixed value for the y-intercept of a trendline. While it can be useful in certain cases, it does not directly provide the measure of fit of the trendline.
Therefore, the correct answer is R-squared.

Which of the following is true of the R-squared (R2) value in Excel's Trendline function? Group of answer choicesA value of 1.0 for R2 indicates maximum deviation of the data from the line.If the value of R2 is above 1.0, the line will be at a perfect fit for the data.The value of R2 will always be between -1 and 1.As the value of R2 gets higher, the line will be a better fit for the data.
