histogram comment on the following: Which graph looks closer to Normal distribution, the one for the 6 classes or the one for 11 classes?

q,

Which one is supposed to look closer to Normal distribution, the one for the 6 classes or the one for 11 classes?

The qqplot is the best visual determination whether data is

∼N

. The closer it is to the line, the closer is the distribution to

∼N

. Comment on the graph. Does it seem that proportions are close to

∼N

? What could be one reason why we see a deviation from

∼N

in the phats based on simulated data? Your histogram for 11 classes should have looked like the second histogram from the right. Did your histogram in Part 1 look more like it was

∼N

? As you see, the number of classes matters for histograms.
