**, (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,**

**FX: 4,6,8,10**

**FX-Xbar: 10,8,6,4,**

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….

__IN A CLEARER WAY:__

→ **,** comma means NEXT LINE

(e.g)

x : 1**,**2**,**3

fx : 4**,**5**,**6

fx-xbar : 10**,**8**,**6**,**4

x|fx |fx-ẍ|

1| 4 | 10 |

2| 6 | 8 |

3| 8 | 6 |

4| 10| 4 |

__ANOTHER EXAMPLE:__

**Class interval:**

60-64**,**65-69**,**70-74**,**75-79**,**80-84**,**85-89**,**90-94**,**95-99.

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**,**351.12**,**333.06

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