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:
