Statistics



#2

Good Day,

I have an HP 49g calculator and I am trying to get used to the statistic-funktion.

when I have for example such a table

Return Probability

10% 0.2
14% 0.1
15% 0.3
16% 0.2
17% 0.2

how can i for example calculate the mean or median?

Hope that anyone can help!

Thank you in advance,

Rgards
Jac

Hi, Jac;

in your table, we can see:

Return          Probability

10% 0.2
14% 0.1
15% 0.3
16% 0.2
17% 0.2

(I restored the original format)

The best way to analyze statistics (at least I consider it so) is by performing statistic functions after entering data with [SIGMA+]. [SIGMA+] is a standard function that collects n-column, single row vectors in Level 1 (RPN entry) in order to compose statistical data. This way, matrix (SIGMA)DAT is generated (something like):

[ [ 10% 0.2 ]
[ 14% 0.1 ]
[ 15% 0.3 ]
[ 16% 0.2 ]
[ 17% 0.2 ]]
After that, performing MEAN returns a single row matrix with the mean for each column. The HP28/48/49/50 series allow a n-th column matrix as data for statistics computations, and some functions apply to all columns, like MEAN and SDEV (Standard Deviation). Other functions/commands (like forecasting) need the target columns to be selected prior to execution (default goes to first and second columns).

Hope this helps (and hope my answer is accurate; I have not a single manual nor a calculator to check names and procedures, though...)

Cheers.
