Excel Statistics 59: Discrete Probability Mean & Standard Deviation SUMPRODUCT function

The standard deviation in "descriptive statistics" in "data analysis" is sample standard deviation not population SD. How can I get the population SD?

Hello,
I have a big set of data with various characteristics. I need to calculate average and stdev of a subset belonging to particular group. I used "averageif" function - worked perfectly - and am looking for something like"stdevIF" - can someone help me, please?
Thanks in advance,
V.

Hi there,

I'm trying to get the standard deviation of acceleration and deceleration of a range of cells. However, I keep getting the same result for both. I filter the cells in the range each time to display positive and negative values respectively. However, what can happen is that in the range the car might only be accelerating (or decelerating) the there will be no deceleration values (or acceleration values). In that case it should return the #DIV/0! error but it it is not.

Any ideas what is happening?

thanks

Code:

   ''Standard deviation Acceleration

    Worksheets("raw").Select
    With ActiveSheet

            .AutoFilterMode = False
            .Range("a1:j1").AutoFilter
            .Range("a1:j1").AutoFilter field:=7, Criteria1:=">0"  'only display cases of acc
    End With

    
    StandardDevAcc = Application.StDev(Worksheets("raw").Range(Cells(sp, 7), Cells(ep, 7)))
    Worksheets("kinematic").Activate
    ActiveCell.Offset(0, 16).Value = StandardDevAcc
    
    'Standard deviation Deccceleration

    Worksheets("raw").Select
    With ActiveSheet

            .AutoFilterMode = False
            .Range("a1:j1").AutoFilter
            .Range("a1:j1").AutoFilter field:=7, Criteria1:="

Hello!
I have this formula:
and i need to make vba code

x = range 1
f = range 2

I have started:

Code:

Function SN(x, f)
'------------------------------------------------

sum = Application.SumProduct(x, f)
avg = sum / Application.Sum(f)
fi = Application.Sum(f)
'------------------------------------------------
For Each a In x
minus = (a - avg) ^ 2
Next a

For Each b In f
xf = xf + minus * b
Next b

'------------------------------------------------

SN = (xf / fi) ^ 0.5
End Function

Something isnt right!
Need help!

In 3 rows (B1:B3) and in 5151 columns (till column GPD) I got alle the combinations which sum up to 1. (Thanx for the help in an other thread).

The first return I calculated in the following way.
=MMULT(TRANSPOSE(B1:B3);H12:H14)-1

The Standard Deviation is calculated in this way.
=SQRT(MMULT(MMULT(TRANSPOSE(B1:B3);C24:E26);B1:B3))

See attached excel sheet.

It would be very helpful if a VBA script can be written which automatically calculates the 5151 returns and the 5151 standard deviation.

Hello, can anybody help me in this problem?

I would like to find the standard deviation of 10 cells in a column B9:B18. The sd should only include any number equal or larger than 0 in the range, but not any blank cells.

I did try the formula STDEV(B9:B18), but the outcome took blank cells as 0.

TQ.

Hi Guys,

Just wanted to ensure ive got my methodology for calculating a standard deviation correct (workbook attached with forumula currently).

Then I will attach a file with it converted in VBA, but i may need a bit of help.

Just attempting to get to grips of the basis before i try to code it, would be intresting to see if we have any other macros for various calculations.

If my calculations are way off then any advice would be great

Hi there, not sure if this is the right forum for this post, but anyway, here it goes.

I have a column of historical 5-year returns. For this data I need the standard deviation of the annualized results (that is, the 5-year returns raised to the power of 1/5). Is it possible to do this directly with the Stdev formula in Excel, or do I have to make a separate column for the annualized returns?

Regards

In regards to Statistics, I was wondering if there is a standard deviation
function in Excel that will eliminate the long math.
