00:00:00.000 --> 00:00:08.092
Here is the problem: Data: 11, 10, 14, 26, 13, 26, 2, 26.

2
00:00:08.542 --> 00:00:11.456
Measures of central tendency for a list of numbers.

3
00:00:12.256 --> 00:00:15.286
Sort the data from smallest to largest.

4
00:00:15.736 --> 00:00:19.161
Mean: add the values and divide by how many there are.

5
00:00:19.611 --> 00:00:27.657
Median: the middle value of the sorted list. With 8 values (even), the median is the average of values 4 and 5.

6
00:00:28.107 --> 00:00:32.948
Mode: the value(s) that appear most often. Most frequent: 26.

7
00:00:33.748 --> 00:00:36.453
Range: largest minus smallest.

8
00:00:37.253 --> 00:00:46.785
So the answer is Mean equals 16; Median equals 13.5; Mode equals 26; Range equals 24.

9
00:00:47.235 --> 00:00:56.767
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
00:00:57.567 --> 00:01:05.160
Sum 128 equals mean times n equals 16 times 8 equals 128.
