In this question, we want to take a look at the characteristics of a normal distribution.
00:06
So first, i'm going to draw the normal distribution.
00:09
It is a bell -shaped curve and is symmetrical about its mean, which is at the center here.
00:20
And the mean for the normal distribution is the same as the median and is same as the mode.
00:28
And since there's only one mode, it is unimodal.
00:36
An area under the entire bell shape curve, that will be the total area, is equal to 1.
00:49
And probability of, for example, this is a.
00:54
Probability of x less than a would be the shaded area from the left side all the way to a.
01:06
Let's take a look at which of this is not a characteristic of the distribution.
01:14
The first one, the curve never touches the excesses.
01:18
That is correct.
01:19
See, even at extreme values, the curve can be very close to the excesses, but never quite touch the excesses.
01:25
So this is true.
01:28
So this is a characteristic of the normal distribution...
