Transcript
The problem. Here is the problem: Data: 6, 5, 19, 26, 28. Measures of central tendency for a list of numbers.
Steps, part 1. Sort the data from smallest to largest. Mean: add the values and divide by how many there are. Median: the middle value of the sorted list. With 5 values (odd), the median is value number 3. Mode: the value(s) that appear most often. Every value appears exactly once, so there is no mode.
Steps, part 2. Range: largest minus smallest.
The answer. So the answer is Mean equals 16.8; Median equals 19; Mode equals no mode; Range equals 23. The mean balances all values, the median splits the sorted data in half and is less affected by outliers, and the mode is the most common value.
Check. Sum 84 equals mean times n equals 16.8 times 5 equals 84.
