Question

Use the data set below to determine measurements of central tendency. (45, 65, 30, 50, 20, 30)

Answer 1

Answer C

mean = 40, median = 37.5, mode = 30

Answer 2

Mean: [45+65+30+50+20+30]/6 = 40.2

Median

First order the number {20, 30, 30,45, 50, 50}

The median is the average of the two values in the middle of the list: (30+45)/2 = 37.5

Mode: 30 and 50 (they are repeated the same number of times)
