Importing data into inference app
I encountered another problem with the Inference app while teaching a physics lab this evening. We were determining the acceleration of gravity by measuring the period of a simple pendulum. I include a screen shot of the data and compute values for g.
D1 = team #1's measured periods (6 trials) D2 = team #1's calculated values for "g" (m/s^2) D3 = team #2's measured periods (6 trials) D4 = team #2's calculated values for "g" (m/s^2) I want to do inference on each team's calculated "g". So first I use the soft menu "Stats". I have a screen shot of the results (I've scrolled to the bottom). I need both means and sigmas. Now I open the Inference app, go to the Num view, and Import. I want #1 to be D2 (team #1's "g" values) and #2 to be D4 (team #2's "g" values). See screen shot. By the way, it would be nice to see the sigma's on this screen as well. I press OK. But the sigma's are WRONG! Everything else got imported correctly, from what I can tell, except for the sigma's. I believe both sigmas are for D1. See screen shot. To fix this, I have to manually enter the sigmas. I believe this to be a bug. |
