[artiny]

hy
i have a problem...i want to calculate for example this:

x = [1 2 3 4 5 6] meanx = 3.5
y = [ ... ] y = ... >>> calc: (xi - meanx )*(yi - meany)

the mean is calculate the casio 991es + in static mode...but how to calculate this 1st part:
(xi - meanx ) ?

in MATLAB we did like this:

( x - mx)*( x - mx)'

where mx is the mean of x.To calculate (xi - meanx ) on a Casio 991ES + calculator in static mode, you can use the following steps:1. Press the "STAT" button to enter the STAT mode.2. Enter your list of numbers for x, and press the "=" button.3. Press the "A+B" button to add all the numbers in the list.4. Press the "÷" button, followed by the number of elements in the list (in this case 6).5. Press the "=" button, which will give you the mean of x.6. Enter the list of numbers for x again.7. Press the "–" button to subtract the mean from each element in the list.8. Press the "=" button to get the result.
