The range is #4#.
The mode is 2,4.
The median is #3#.
The mean is #3#.

Explanation:

The range is the largest number minus the lowest number.
#High 5 - low 1 = 4#

The mode is bi-modal because there are two equal occurrences of two repeating numbers in the range.

The median is the center number when the numbers are written in order from smallest to largest: #1, 2, 2, 3, 4, 4, 5#.
This number is #3#.

The mean is the average value of all the numbers and is equal to the sum of the numbers divided by how many there are in the range. There are seven numbers here.

#mean = (4+1+3+4+2+2+5)/7 = 21/7 = 3#
