Question

Your Desmos calculator also finds the correlation coefficient, `r.`



6. Locate the `r-value` on your calculator and type it below:

Answer 1

I can’t see your Desmos, so I can’t read the r for you. Paste the value here or follow these steps to find it in Desmos:

1. Enter your data as lists, e.g. x1 = [..] and y1 = [..].
2. In a new expression type the regression: y1 ~ m x1 + b
3. Desmos will show the regression output including m, b and the correlation coefficient r (and often r^2).
4. Copy the displayed r (a number between -1 and 1) and paste it here.

If you want, paste a screenshot or the numbers and I’ll read off and interpret r for you.
