Mean is just another word for average. To find the average, add up all the values then divide by the number of values.
There are 7 values in the first data set. The average is:
(3 + 4 + 6 + 4 + 3 + 1 + 4) / 7 = 25/7 ≈ 3.57
There are 7 values in the second data set. The average is:
(6 + 7 + 2 + 4 + 5 + 5 + 3) / 7 = 32/7 ≈ 4.57
