00:01
So the question here is about talking about data analyses.
00:04
More specifically, we're looking at statistical studies.
00:08
So we have statistical studies here.
00:11
So we're given a data plot representing the final examination grades for an elementary statistics course here.
00:17
So for part a here, it wants us to conduct a stem and leaf plot.
00:19
So i'm going to do a sample here and we'll let you do the rest.
00:23
But a stem and leaf plot is essentially as follows.
00:25
So this part is going to be the stem and that is going to be the leaf.
00:28
Whereas, for example, if we have a value of, let's say, one, two.
00:34
Essentially, what you put is that, for example, in our value, we have the smallest number here is going to be 10, so we add a 0 here.
00:41
The second smallest is going to be 5 and then 7.
00:47
So we read it like such.
00:48
So that's going to be 10, 15, and 17.
00:52
So for the 20s, we can do, let's say, a couple of numbers.
00:55
We can do, let's say, three, we can say five, and that's going to be read as 23, 25.
01:02
And that's essentially how you do it...
