We have been given a dataset.
00:01
We want to get the mean, median, mode, and outliers.
00:05
Let's start with the mean.
00:07
To get the mean, you take each value, you add them all up to get a sum, you divide by the total number of pieces of data.
00:15
So if i add all of these up, i get 1065, and there are 25 pieces of data, giving us a mean of 42 .6.
00:31
Medium.
00:31
Actually, i'll do the mode first.
00:34
The mode is just the most frequent piece of data.
00:38
It's possible to have no mode if they all have the same frequency.
00:42
It's possible to have multiple modes.
00:44
Let's see what we have here.
00:45
Most pieces of data only have a frequency of 1.
00:48
There are three 24s, there are three 50s, there are five 33s.
00:54
So 33 is the most frequent value here.
00:59
Next, the median.
01:01
The halfway point.
01:02
Half of the values are below it, half are above.
01:06
So it's already in ascending order, we just need to find the n plus 1 over 2th piece of data.
01:13
N is 25, so we need the 13th.
01:18
So for example, the first is 12, the second is 15, the third is 19...
