In number 15, we're asked, what is the standard distribution curve? what are its characteristic? i think this would have been a great number one, because we've already been using the normal distribution curve.
00:14
But whatever, let's answer it.
00:16
Now, what can we tell about it? there is no answer in the manual for this, so you'll have to bear with me and consider that there might be more to it than what i found.
00:30
But here are the characteristics i found i think are really important to the standard normal distribution.
00:43
So this is not any standard normal distribution.
00:48
This is the bell shape one that has a mean of zero and a sigma of one, sigma being the standard deviation.
01:05
So those are two very important characteristics of the curve.
01:11
Another one we could tell is that the total area is one.
01:16
I mean, this is always the case, but it's for any probability density function, but it's also a characteristic of this specific one, which is an important one.
01:29
We could say it goes from minus infinity to plus infinity, which maybe i should write a little differently instead.
01:40
We should say that x is between minus infinity and plus infinity.
01:46
If we say this axis is x here.
01:49
So this curve goes all the way to minus infinity and all the way to plus infinity.
01:56
And then another thing we could say about it is describe it as a function...
