I need to determine probability when user create first file during a day. I have time stamp in format HH:MM:SS. of creation first file during one year period. In order to determine distribution I created histogram in a way to create binds (10 minutes range) and count frequencies. Based on histogram this could be a gamma distribution as possible solution. For gamma I need mean and standard deviation.
Question is can I convert HH:mm:ss time stamp to seconds and calculate mean and standard deviation.
Similar research I found on internet about baby delivery but no methodology explained.
this graph show 8 h of working day activities ( 08:00 - 16:00) , based on 10 minutes range - 10 hours - if some one came earlier or stay longer and produce file.
