Plotting of distribution curve

witchdoc · Jun 26, 2002

Is there an easy way to extract distribution curves from a data table? We currently record bag weights into an excel sheet. We are manually generating distribution curves and identifying the number of bags exceeding tolerance. This is a very tedious process and prone to error. Any suggestions?

Sorry, I don't understand what you are trying to do.

If you have a list of numbers then finding the standard deviation and mean is trivially easy, and you can then plot the Gaussian distribution using the obvious function.

On the other hand if you are trying to bin your results then that is done using FREQUENCY.

Is either of those right, or is it something else? Cheers

Assuming that you have activated the "analysis tool pack" you then just use the histogram function.

If you wish to use the same "bins" each time then you can specify that. You can add a accumulated frequency - wich you can plot as distribution.

Descriptive statistics will give you more numbers such a stdev etc.

Thanks to both of you. Both solutions worked well.
