YOU CAN ASK QUESTIONS IF YOU ARE CONFUSED WITH ANY SYMBOL. ================= ....YOU ARE ADVISED TO USE A BETA PHONE....NOT SMALL CHINA PHONE TO AVOID AMBIGUITY / means DIVISION * means multiplication tita you should know that. raise means raise to power ^ means raise to power sqr rut/ squar 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 IT IS FOLLOWING i.e 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-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.. YOU NEED TO KNOW THESE ALSO: MATHS CODES: 1) ,(comma) means next line. (e.g) x : 1,2,3 fx : 4,5,6 fx-xbar : 7,8,9 x|fx |x��| 1| 4 | 7 | 2| 5 | 8 | 3| 6 | 9 | 2)*=multiplication sign. 3)^ = Riase to pwer 4)P also means raised to power eg 10P6 means 10 raised to power six. 5)log3(base 4) ..Note:the base must be SUBSCRIPT . 6)x bar = mean symbol(x��) 7)Pie = pie symbol eg Area of a circle is (Pie r2). 8)Tita = θ eg Sinθ. 10)Root or Rut or Sqrt or sqr root = √ ; eg Root2 means √2 11)/ means � 12)----(1) means equation 1 Drop any question below now!
