Question

Very eazy question , eazy points , What formula to use in statistics for variance and mean deviation using The fiui format and what is ui?explain in ur own words , idk , but plz explain. ​

Answer 1

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..
