Can anyone show me how to make a residuals plot and a normal probability plot in TI-84 ?

2011-04-13 2:24 am
So, I am doing the interval for regression. And I am making the assumption of the samples. I was given two data, after I enter the data into my calculator, I found that I don't know how to
make a scatter plot to show that the there should be no pattern in the residuals plot.
After that, I also need to check if the distribution of the residuals are normal.

I am confused, because I saw there are two graph (the solutions) on my books which can response to the assumptions above. I just need someone guide me to make these teo graph in TI-84. Thank you!!!

✔ 最佳答案
1) Enter data in L1 and L2
2) Run the appropriate regression command ([Stat] > Calc)
3) Hit [2nd][Y=](Stat Plot) and choose 1:Plot1
4) Turn it On, make sure Scatterplot is the correct type, and change Xlist to RESID (should be under [2nd][Stat](List)).
5) Hit [Zoom] > 9:ZoomStat to view the residual graph.
