Given that the computer graphs for the generated data, note: 6 classes, rather than 5 for the
1^(st )
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.
