    What type of data (Continuous or poison) would I be analysing – The number of calls received in different hours of a day? As I could calculate the average number of calls (Mean) in the different hours and the variation between (Spread) them it appears like a continuous data. But on the other hand as I am counting the number of occurances (calls) which can’t be a decimal it appears like a discrete (poison data).

    I did a project sometime back which was very similar to yours. Even though people suggest that you use counts as poisson distribution, however, as top statisticians agree that when you have large distribution  the counts starts approaching a continuous data set and resembling one as well. Therefore, I used them as continuous as well and with great results.

    Since it is for the org. I work for, therefore, may not be able to share all the details. However, if you want very specific input, I’m more than happy to share.
    You can send me an email at [email protected] or use this forum.
    cheers,

    Hi,
    I would take the number of calls in different hours as discrete data as we are counting. If it were measuring the duration of calls and taking an average of that, then it would be continuous data. From what I could perceive, the data appears to be a continuous data due to its spread, but the spread could be because of the peak hours and off-peak hours, and can be best used to schedule your work force accordingly.
    Is that the definition of problem?
    Regards,
