Kristina Armstrong · Answer 1

389 / 10 = 38.9 (mean)

80 / 2 = 40 (median)

Alfonso Diaz · Answer 2

to find mean, add all the numbers, then divide that by how many numbers there are. so: (10+31+36+36+38+42+47+48+49+52) / 10 = 389/10 = 38.9

to find the median, you arrange the numbers from smallest to largest, and the one in the middle is the median. in this case, there are 2: 38 and 42. so now we need to add these then divide by 2: 80/2 = 40
