Mean, mode, and median in these sets of numbers 55, 50, 73, 61, 68, 48,48

Mean = (403/7) or about 57.57
Mode = 48
Median = 55

Explanation:
Mean is (total)/(amount of values). In this case its (55+50+73+61+68+48+48)/7, which equals (403/7) or about 57.57

Mode is what value shows up the most. In this case its 48, which shows up twice, compared to the other values which only shows up once.

Median is the middle number when the values are arranged from least to greatest.
48, 48, 50, 55, 61, 68, 73
In this case if you count 3 from both sides, the center or middle is 55, which is the median.
