Answer:
ui mainly refers to the observations
Mean deviation= |Mean-xi|/N
where xi mainly refers to the observations
N = total number of observations
Variance= (Mean-xi)^2/N
Let me take an example for your clear understanding,
2,3,5,4,6
Here,
Mean=(x1+x2+x3+x4+x5)/5
= (2+3+5+4+6)/5
= 20/5
= 4
Note that- x1,x2 these are all xi or you can say ui
Let's check the above attachment for all the rest of the part
Hope the answer helps you..
