30, 32, 35, 34, 36, 40, 32, 33, 36, 41, 44, 37,

Calculate the mean. Calculate the standard deviation

Steps using Calculator fx-82EX:

log into Statistics w2

Choose 1- Variable 1

fill up the table

30=32=35=34=36=40=32=33=36=4

1=44=37=

click option key T2 for calculation.

Example 1 : Check whether the function ( ) =

(1,5).

Q)d+3==1=5==

The table will show the result, now look at the f(x)

Values are they increasing or decreasing?



downword or upword in "x" column and replace it by any "x" value

Example 2 : change the 1

Steps :

15=

"x" value by 15

+ 3 is decreasing or increasing over the domain
