1. Find the mode of the following data:
12, 14, 12, 16, 15, 13, 14, 18, 19, 12, 14, 15, 16, 15, 16, 16, 15,
17, 13, 16, 16, 15, 15, 13, 15, 17, 15, 14, 15, 13, 15, 14
Data | Tally bars | Number of times |
12 | 3 | |
13 | 4 | |
14 | 5 | |
15 | 10 | |
16 | 6 | |
18 | 1 | |
19 | 1 |
Clearly, 15 occurs 10 times. Therefore, 15 is the mode of the data.
