Simple Pendulum Question

I did a Simple Pendulum experiment in my college physics class the other day. We were asked to graph a T^2 x L graph based off our results. I plan on using the Length on the x-axis and the T^2 on the Y-axis.

This may seem like a simple question but how would I find my T^2? Is it just simply the Period (T) that we timed but squared? For example: T = 1.10s is 1.21 T^2. Or, is there some kind of formula I need to find T^2? Here is a picture of my table that will hopefully clarify:F8022A78-953A-4926-9331-EBB0980C174E.jpeg

Based off my picture above, should I plot my first coordinate at (28, 1.10) or (28, 1.21)? Or something else?

Thanks!

On the dance floor, baby!
You got it right. Just use the list of numbers for \(\displaystyle T^2\) as your y values.
