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-x��|

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

NOTE THAT WHEN YOU SEE SOMETHING LIKE THE ABOVE TWO EXAMPLES, YOU WILL NEED TO DRAW A TABLE..
