00:00:00.000 --> 00:00:06.119
Here is the problem: Data: 3, 22, 20, 30, 22, 25.

2
00:00:06.569 --> 00:00:09.495
Measures of central tendency for a list of numbers.

3
00:00:10.295 --> 00:00:13.116
Sort the data from smallest to largest.

4
00:00:13.566 --> 00:00:17.026
Mean: add the values and divide by how many there are.

5
00:00:17.476 --> 00:00:25.568
Median: the middle value of the sorted list. With 6 values (even), the median is the average of values 3 and 4.

6
00:00:26.018 --> 00:00:30.708
Mode: the value(s) that appear most often. Most frequent: 22.

7
00:00:31.508 --> 00:00:34.097
Range: largest minus smallest.

8
00:00:34.897 --> 00:00:46.577
So the answer is Mean equals 20.33333333; Median equals 22; Mode equals 22; Range equals 27.

9
00:00:47.027 --> 00:00:56.884
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.

10
00:00:57.684 --> 00:01:07.320
Sum 122 equals mean times n equals 20.33333333 times 6 equals 122.
