Statistics is a very important part of mathematics. Mean ( x̅ ), Standard deviation(σn, σn-1), Σx, Σx2 etc can be calculated with calculator for any given data.
Example: The numbers of students of different class of a school are 55,58,51,63,55,59,51,60,53,55.Calculate mean ( x̅ ), Standard Deviation (σn, σn-1), Σx, Σx2 for the these
data.
Solution:
(Mode initialization)
MODE >> MODE >> 1(SD)
(Clear memory Important, any previous statistical calculation data interfere with present calculation resulting error if this step is not followed. So before starting every statistical calculation statistical memory must be cleared)
SHIFT >> MODE >> 1(Scl) >> = (Stat clear)
(Input data)
5 >> 5 >> M+(n=1) >> 5 >> 8 >> M+(n=2) >> 5 >> 1 >> M+(n=3) >> 6 >> 3 >> M+(n=4) >> 5 >> 5 >> M+(n=5) >> 5 >> 9 >> M+(n=6) >> 5 >> 1 >> M+(n=7) >> 6 >> 0 >> M+(n=8) >> 5 >> 3 >> M+(n=9) >> 5 >> 5 >> M+(n=10)
(Calcuation of Σx, Σx2)
SHIFT >> 1 >> 1(Σx2) >> =
SHIFT >> 1 >> 2(Σx) >> =
(Calcuation of x̅, σn, σn-1)
SHIFT >> 2 >> 1( x̅ ) >> =
SHIFT >> 2 >> 1(σn) >> =
SHIFT >> 2 >> 3(σn-1) >> =
(edit input if necessary,suppose we have to put 59 in place of 58(n=2))
This is the basic operating system of calculator in statistical mode.It will save your time and make the problems easier.

∇(Bottom of replay button) >> ∇(x=1) >> ∇(x=2) >> 5 >> 9 >> =
(In the same way edit any input)This is the basic operating system of calculator in statistical mode.It will save your time and make the problems easier.
