Okay, so to make a stem plot, we're going to start with, so nine and then a six.
00:16
You got to put him in order.
00:18
This means 96.
00:21
Okay.
00:23
Then we've got 10, which there's not a 10, which means, and then 11.
00:32
So that's going to be 110, 11, 1 .18.
00:40
And 118 and then 12 because this is our 10 splice this is our 1 spice so 12 12 12 12 25 126 all right so that's 130 so that's 130 oh i got that 126 sorry and then a 9 got it and then 14 with a 5 so that's the stem and the stem plot for the data.
01:21
Hey, hello.
01:28
Okay, i think i missed a question.
01:29
Is this please compare the mean and the median value using a bell curve shape? so if the mean and the median are the same, that means it's normal distributed.
01:42
So the mean and median are equal when it's a bell curve.
01:55
Now, if the curve is skewed, say like that, to the left, well, this is using the bell shape of color with the mean.
02:08
So the main is, this would be, this would be the mean is less than the median.
02:29
Okay, because that means it's to the right.
02:31
If it's to the left, if it's bigger than the median, it's going to look like this, where your main is over here and your data goes over here.
02:40
So it's going to be skewed left.
02:47
Okay.
02:49
The five number summary, the first thing you need to do is make sure they're all in order and these are not.
02:53
So let's put them in order.
02:55
So 5, 7, 12, 12, 12, 13, 15, 16, 21, 21, 28 .5.
03:24
Oh, it's 26.
03:34
21, 21, 26, 28 .5, 29, 38, 38, 28, 28, 2, 2, 42, 38, 39, 29, 2, 9 .2, 42, 44 .8.
04:01
All right...
