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…..

fx-xbar : 10,8,6,4

x|fx |fx-ẍ|
1| 4 | 10 |
2| 6 | 8 |
