How does one determine the percentage of a sample less than or equal to some x value for a set of discrete data that appear to be right-skewed? For example, I have a number of data points, and if I were to draw a curve through them it would look something like this:
What statistics are most relevant for a sample that appears to be drawn from a right-skewed distribution (suppose we assume that it is from such a distribution based on the result of the sample)? For example, what would be the best measure of deviation for such a distribution? As mentioned by Nick it seems like the negative binomial distribution with a shape parameter $r$ of around 5.
