the range is the range that the values take, so you would give the minimum values and the maximum as the range minimum - maximum

the mean is all values added divded by the number of values

median is the middle value if all values are arranged in ascending order (if there is no middle, take the average of middle two)

the mode is the number that occurs most frequently

i'm sure you can work it out from there
