PROGRAM MEANWT

Interactive calculation of weighted means

Description:

The program calculates the weighted mean of sets of data typed at the terminal

Input:

Data are read interactively from the terminal

Output:

A listing file which contains the input data and the results of all the calculations

Notes:

If the esd's of the data are not known they can be given as 1 to give unit weights.

Running the program:

On running the program the user is asked successively to give x and dx which are the value and esd of one of a set of observations whose mean is required. If a RETURN rather than a value is typed the weighted mean of the current set is calculated and printed on the terminal, followed by the esd's calculated first from the deviations from the mean, and secondly from the given esd's of the data.
A RETURN typed when there are no data in the set terminates the program.

Calls:

ASK INITIL RDNUMS WTMEAN

Common blocks used:

/IOUNIT/ to use LPT ITO
