equation of linear trendline on ipad
On a PC, I can make an XY scatterplot, and get a trendline, and get the equation and R squared value. But on an ipad, I cannot get the equation of the line. I have a lab exercise with my college students that requires them to make a scatterplot, and then use the equation of the line to predict Y values given an X value, or vice versa. Our college just purchased new ipads for all students, so I was very disappointed they cannot use their new ipads for this exercise.
Please add trendline
You can in version 2.9. Add some data, insert a chart/XY scatterplot, tap on the layouts button in the Chart menu, and chose the 9th chart layout from the top. This a chart layout showing the estimated coefficient of linear regression and the R squared.
