Hello everyone.
00:02
So in this question, based on the data given on the 1995 students who have gone through the mba program at state university, we have to find mean and standard deviation for each of the numerical variables in this population.
00:19
So let us summarize it in a table.
00:24
So the specifications are age, children, g -mat score, previous salary, salary, monthly expense and one is school debt.
01:18
So mean standard deviation, mean standard deviation.
01:28
Okay, the formula we are using to calculate mean is sum of all observation divided by number of observation.
01:48
That is, if xi represents the observations, then mean is given as submission xi.
01:54
Submission over i divided by n where n is number of observation so using this the mean for all these specs become 32 .3313 .0 .2621 7303 .12 703 .1 to 56 .15648 .5 .1 ,1832.
02:35
And that for school debt is 27312 0 .08 coming to standard deviation.
02:45
So standard deviation is given as summation x i minus x bar whole square divided by n minus 1 square root where x i summing right where x are observations and x bar is mean that is this value right so using this formula the standard deviation for different specs becomes 3 .5731 for children 0 .547.
03:27
G -mat score 41 .2401.
03:33
For previous salary, 119 ,000.
03:40
Okay, it's 11 ,953 .35.
03:46
For monthly expenses, 424 .78...
