Question

Standard deviation for n observations $x_1,x_2,\dots x_n$ is 5, then the standard deviation for n observations $x_1+1,x_2+1,\dots x_{n+1}$ will be ___

Answer 1

We have seen that standard deviation is the measure of spread, basically, it gives us the idea how spread the data is, on adding or subtracting the data with any constant number 'a' it doesn't change, so it'll be same.
