Question

Which of the following actions will have no effect on the value of the standard deviation?

Answer #1

Solution:

If we increase or decrease sample size than standard deviation will change

If we increase or decrease any value in standard deviations with different values than standard devaition will also change.

But if we increase or decrease all values in sample by same amount than the standard deviation will not get changed.

So if there are so many observations in sample and all observations subtract by 5 than there will not be any effect on standard deviation.

1. what effect does increasing the sample size have on the
population standard deviation?
If the sample size increases then the sample standard deviation
will be decreases. But in this sentence, it is not a sample
standard deviation. Every answer in CheggStudy is decrease.
I think sample size doesn't affect to the population standard
deviation.
