I have a small data sample of some occurrence in time. For an example lets take the time it takes kids to finish their lunch to determine wether a school has given them enough time for recess.
The times are (20,15,12,18,15,13,13,10,14,14,15,17,8,22,16) in minutes.
What distribution should I use?
Should I just calculate the mean and std. dev. from the data and generate a normal distribution, like below?
Sample(X,3) # generate a few samples
I could also randomly choose from the observed 15 data points.
combinat[randcomb](a,3) # randomly pick 3 of data points
Which method would be better? Is randcomb following any kind of distribution?
