I am looking at submission data—the length of time it takes for someone to complete a flow which involves submitting an item of content. I am getting the following distributions. I have two quick questions:
What best describes the frequency distribution? I am thinking lognormal but am not sure.
Is the mean the best statistic to use, e.g., 'mean submission time is hh:mm'? Is there a better, e.g., median or % of submissions below hh:mm?
