Hello everyone.
00:01
So in this question, it is asked, what is the phrase meaning having degree of freedom as it pertains to the computation of the sample standard deviation means? so when we talk about standard division, it is a statistical measure which is used to find the variation of data set.
00:14
And it is a measure used to describe how far the data observation of a data set from the mean is there.
00:20
So the most commonly used measure of spread is, first of all, we have the sigma that is given by population of standard deviation.
00:28
So this is meaning population, standard deviation.
00:36
And it has a formula of summation, square root of summation of sigma xx minus x bar, the whole square square divided by n.
00:48
So this n includes all the population observation in computation.
00:53
And then we have this next one, which is s, that is the standard deviation, standard deviation, having the formula square root of summation x i minus x bar the whole square divided by n minus 1.
01:12
When we see over here, the difference in this is that in this case n is there.
01:17
That means all observations are considered...
