Have you considered calculating the values?

triciaal · Answer

the mean is the average ; add up all the numbers and divide by the number of entries here you have 25 numbers
the mode is the most frequent
the mediam is the middle entry   put the numbers in numerical order and find the one in the middle  here the 13th entry   (25/2 12 1/2) 
use the formula to find the standard deviation   it is a measure of how far away from the mean 
the range would be the lowest entry to the highest entry
What is the five-number summary?

Five Number Summary. For a set of data, the minimum, first quartile, median, third quartile, and maximum
