00:00:03.390 --> 00:00:04.740
<v Speaker>Okay. Hello students.</v>

2
00:00:04.740 --> 00:00:07.830
Now we are going to 1C,

3
00:00:07.830 --> 00:00:11.190
where we are gonna learn how to compete the median.

4
00:00:11.190 --> 00:00:15.720
So calculating the median is actually quite simple.

5
00:00:15.720 --> 00:00:19.360
What the median is, is our physical midpoint

6
00:00:21.060 --> 00:00:25.653
but it is the physical midpoint of the ordered data set.

7
00:00:28.050 --> 00:00:31.683
So we have, first and foremost, learned how to do that.

8
00:00:32.850 --> 00:00:35.461
So we are going to write down again,

9
00:00:35.461 --> 00:00:36.743
the ordered data set here.

10
00:01:04.140 --> 00:01:07.410
So now, what I'm going to do is go here

11
00:01:07.410 --> 00:01:12.363
and select a different color for my pen tip, like a pink.

12
00:01:13.560 --> 00:01:18.560
And I am going to now kind of put the numbers here.

13
00:01:20.010 --> 00:01:25.010
So basically, this is the first, second, third,

14
00:01:25.290 --> 00:01:30.290
fourth, fifth, sixth, seventh, eighth and ninth.

15
00:01:32.370 --> 00:01:35.310
So this is basically our order data set,

16
00:01:35.310 --> 00:01:37.440
smallest to largest.

17
00:01:37.440 --> 00:01:39.630
So now, we are looking for the physical midpoint.

18
00:01:39.630 --> 00:01:43.560
So as we all know, when our set of numbers is nine,

19
00:01:43.560 --> 00:01:46.680
then the physical midpoint is going to be five.

20
00:01:46.680 --> 00:01:51.300
So this is going to be our median.

21
00:01:51.300 --> 00:01:53.650
So again, key here is

22
00:01:57.270 --> 00:01:58.860
an ordered set.

23
00:01:58.860 --> 00:02:03.780
So in an ordered set, your median is your physical midpoint.

24
00:02:03.780 --> 00:02:04.613
Very simple.

25
00:02:06.465 --> 00:02:08.815
Okay, so now we are going to go to the next one

26
00:02:10.131 --> 00:02:10.964
and that will be 1D.
