So the question here is given a series of numbers to find their central tendencies.
00:07
So here is the first set of numbers and the frog watcher problem.
00:14
And there are 10 numbers that are listed here.
00:18
The first set that we're being asked to solve for the central tendencies is the mean.
00:23
And on the mean, what you basically are going to do is add up the total and the series of numbers.
00:28
And i have 3 ,8004.
00:31
And then divide since there's 10 units of numbers, if you will, 10 sets.
00:36
I divide by 10.
00:37
So the average or the mean is 380 .4.
00:42
In the second series of numbers that were given and we're supposed to find the central tendencies, it goes from 6 to 100.
00:49
And what we're supposed to be doing is, again, finding the mean.
00:53
So for this second series, we again add the numbers up, 2 ,769 and divide by 10.
01:01
So the average or the mean in this series is 276 .9.
01:10
So the first mean we get is 380 .4.
01:13
And the second mean we get is 276 .9.
01:17
So then the next one is median.
01:19
And how you solve for median is you have the numbers in the list.
01:24
And you, like, for example, cross out 114 and then 634.
01:27
And then crossed out 130 and 464.
01:31
And the whole point of it is to get somewhere to the middle section.
01:37
And so what we find is in the second set, 2194 is in that second area.
01:44
And what i have to do is average the 219 plus 194...
