If you have the data, drop it into an Excel spreadsheet. Sort the column in ascending order. Count how many rows you have. Divide by two. that midpoint is the median . i.e: there are as many data points below and there are above.
Mean:
Add all of the data together and divide by the number of data ('n"0
Mean = sum of all data / n
"Mean" just refers to "the average".
Range:
Remember how you sorted the data for the median? using that same sort, just provide the lowest and highest data points.
