Once again, welcome to a new problem.
00:05
This time we're dealing with descriptive statistics.
00:09
We're dealing with descriptive statistics.
00:12
And when it comes to descriptive statistics, we have tables.
00:20
We also have numbers and we have graphs.
00:26
So you have tables, you have numbers and you have graphs of pieces of represent.
00:32
Information with the numbers you have measures measures of spread and measures of central tendency and measures of spread you have the range you also have the standard deviation which comes together with the variance so you have the standard deviation which is connected to the variance and then you have the iqr which also happens to be the interquotile range so the iqr is the interquotile range as a measure of central tendency you have the mean you also have the median and of course you have the mode so you have the mean and the median and the mode.
01:36
We have a new problem in looking at this problem and this is based on ncaa football, football coaches, coaches, salaries so we're looking at the salaries of football coaches and so this this is based on 2017 and the salaries are increasing in recent times, so they're increasing in recent times.
02:16
So they're increasing in recent times.
02:21
The annual base salaries, the annual base salaries for the previous, for the previous head football coach, head football coach and the new head football coach at 23 schools given given.
03:00
So we're looking for, we have all this information that's provided in the particular problem.
03:16
And and so based of these provisions these are the numbers you know 26 7 800 so that's what you're seeing right here 267 800 and then of course you know we have all these other numbers that we're looking at for the data we have 47, 47, 456, 210, 202 million we have 300 ,000, we have 300 ,000, we have 300 ,000, we have 493, we have 97, 970 ,000, as you're looking at that.
04:40
We also have other details, $2 ,050 ,000, $375 ,797 ,59, 52 ,183 ,000, 52, 183, 1 ,700 ,000, 2 ,600 ,000, 377 ,000, 37 ,000, 37 ,000, 37 ,000, 3772 ,000, 3772 ,000, 377 -250 and then so that's the annual base salary of the previous coach and the new coach so this is the the previous coach 377 so 725 00001 1769 648 3 5000 we also have 41010 790, 0000, 193, 6225, we find 0000, 420000, 420000, 85000000, and then we also have 200 ,000000.
06:14
So this is the data for the previous coach and then we also need data for the new coach.
06:30
So there is the previous coach and the new coach.
06:33
So 2800525000.
06:40
180 -0 -0 -0.
06:40
And then we have 2 -8 -0 -0.
06:45
0 and then we have 2 0000 375, 525 ,000, 1 ,000, 1 ,800 ,000, 2 million 200 ,000, 375 ,700 ,000, 700 ,000, 1 ,8100, 2 million 300 ,000, 370 ,000, 3 ,000 ,000, 3 ,700 ,000 ,000, 3 million, 300 ,000 ,000, 3 million, 300 ,000 ,000 ,000, 3 million, 3, 3 390 ,850 ,000, 2 ,0296 ,000, 2 million, 292 ,000, 392 ,500, 856, 210, 210, 2 ,121550, 2 ,0 ,250 ,000, 1 ,500 ,500 ,000, 1 ,500 ,500 ,000, 1 ,50000 ,000.
08:13
20350.
08:14
So this is the data that you're seeing in the particular problem and we have different requirements so we want to determine the median annual salary for the previous coach and the new coach.
08:39
I want to determine the medians and then we also want to determine the rate range of salaries for both coaches.
08:55
So the range of salaries for both coaches.
08:58
We want to determine the standard deviation of salaries for both coaches.
09:17
And then of course we're also looking at explain.
09:26
The differences, explain the differences based on part a through c, between the annual base the school pays a new head coach compared to the previous, compared to the previous, compared to the previous head coach.
10:14
So those are the numbers you're looking at in the particular problem.
10:21
So in part a, we're looking at the medium...
