In this question we have given measurement and we have to write its description and then its equation or its symbol from the given data.
00:11
The first measurement is, so first we'll make a box here, measurement.
00:17
The first measurement given to us is sample variance.
00:23
So its description is, as we know that sample variance is, mean squared deviation from the population mean.
00:40
It is mean squared deviation from population mean.
00:54
And formula for this we can write it as in equation column we'll write the formula for this.
01:04
That is equation for temporal variance is s divided by n minus one.
01:09
Now we have given the second is population.
01:16
Variance.
01:19
And here the definition of this is clearing sample it is mean squared deviation from m and in for population it is mean squared deviation from population mean and formula for this is s is divided by n.
01:48
Now in the third we have given sample standard deviation...
