Hello show and we are going to write here we need to find the standard deviation for the given sample data so these data values are given so basically we need to calculate our mean value which is mu that is equivalent to sum of data and this must be divided by if i write here for this let's raise this to make it more clear this must be number of data so basically if i write here this value will come out as 22 .6 plus 16 .1 .0 .20 .3.
00:42
And if i write here for this, this is this must be divided by six.
00:47
So if i write here for this, this value will come out as so total value is 154 and this must be divided by 6.
00:58
So this value would be 25 .8.
01:03
Now we need to calculate our standard deviation.
01:06
So if i write here for this.
01:09
So let's say we are going to calculate population standard deviation in this particular case.
01:16
So population standard deviation value would be if i write here for this, this must be sigma that is equivalent to under root of 1 upon n, that is summation of.
01:29
X i minus if i write here for this mu raise to power two so basically if i write here for this this value will come out as if i write here under root of 1 by 6 and this must be x i x i value is 22 .6 22 .6 minus 25 .8 raise to power 2 plus 16 .1 minus 25 .8 raise to power 2 and this value will come out as so let's erase this to increase this so this value will be if i write here for this so our last value in this particular case is so here plus and this will be the this this value will be up to 20 point if i write here 20 .3 minus 25 .8 raise to power 2...
