rais means Raise to power or

^ means Raise to power
sqr rut/square rut means Square root

—–(1) means Equation 1
yr means Year
f(x-xbar) means x MINUS x BAR as in statistics which means that MINUS will be on Top of x. ,
(Comma) means NEXT LINE,

This means that The Following Number is Under The Number
its Following ie.
UNDER. It is usually used
during STATISTICS when drawing a table.

EXAMPLE

1 X: 1,2,3,4,5,6

FX: 4,6,8,10,12

FX-Xbar: 10,8,6,4,2,1

DRAW A TABLE WITH

X|FX|(FX-Xbar)

The above statement means that:

~ For X, it has 1 2 3 4 5 6 under it.
which means 1 is under 2,
2 is under 1, 3 is under 2, 4 is
under 3 and so on…

~ Under FX you have 4, then 6 under 4, then
8 under 6, then 10 under 8, then 12 under 10.

~ Under FX-Xbar you have 10, then 8 under 10, then 6 under 8, then 4 under 6, then 2
under 4, then 1 under 2.

EXAMPLE 2:

Class interval:
60-64,65-69,70-74,75-79,80-84,85-89,90-94,9

X: 62,67,72,77,82,87,92,97.

F: 2,3,6,11,8,7,2,1.

FX:124,201,432,847,656,609,184,97.

F(x-x bar)2:561.12,414.18,273.36,33.66,84.48,476.42,351.

MEANING OF THE ABOVE EXPRESSION:

Bar means Minus on top of d number or Variable and comma means next line which means each of them are unda.

Eg 60-64 is unda Class interval, then 65-69 is unda 60-64,etc .So comma means unda.

NOTE:When you see something like the above example two, you will have to draw a table. we will update more later!
