Okay, so i see that you need help with this problem.
00:06
So it says some measures of central tendency include mean, median, range, and mode.
00:11
Explain the advantages and disadvantages of each.
00:14
So i'm going to stop right there.
00:15
I'm going to stop right at here and explain the differences or the advantages and disadvantages of the mean, median mode, and range.
00:23
So the first thing, average, is the mean.
00:26
And the advantage is the mean takes account of all values to calculate the average.
00:31
The disadvantage, however, is very small or very large values can affect the mean.
00:38
The median, the median is not affected by very large or very small values.
00:45
If there is an even number of numbers, the median is found by averaging the two middle numbers.
00:53
This means that the median value may not actually be a number in the original data set.
00:59
The mode is the advantage is the mode is the only average that can be used if the data set is not in numbers.
01:09
For example, you can do colors of cars in a car park.
01:13
The disadvantage, however, is there may be no mode, there may be one mode, and it's not always representative of the data.
01:21
The range is the difference between the largest and the smallest observation in the data.
01:26
The prime advantage of the measure of dispersion is that it is easy to calculate.
01:32
On the other hand, it has a lot of disadvantages.
01:35
It is very sensitive to outliers and does not use all the observations in the dataset.
01:41
So then it asks this question which measure would better represent the population below and why do you think so? well, first of all, let's answer these questions.
01:52
Because i think that let's find out this information first and then answer this one.
02:01
Can you please explain the length of stay versus patient? so these are the patient numbers.
02:07
So patient number one stayed maybe for two days...
