Calculate the correlationcoefficient r, letting Row 1 represent the x-values and Row 2 the y-values. What effect does switching the variable have on r?
Row 1 Row 2
1. Calculate the correlation coefficient r, letting Row 1 represent the x-values and Row 2 the y-values.
r = ???? (round to three decimal places)
2. Calculate the correlation r, letting Row 2 represent the x-values and Row 1 the y-values.
f = ???? (round to three decimal places)
3. What effect does switching the variables have on the correlation coefficient?
The correlation (increases, changes sign, remains unchanged or decreases) when the x-values and y-values are switched.
The solution contains the determination of the correlation coefficient for a set of data.
