Determine the mode of the following values of a variable.
23, 15, 25, 40, 27, 25, 22, 25, 20
Answer:
By arranging the numbers in ascending order
We get
15, 20, 22, 23, 25, 25, 25, 27, 40
| Observations (x) | Frequency |
|---|---|
| 15 | 1 |
| 20 | 1 |
| 22 | 1 |
| 23 | 1 |
| 25 | 3 |
| 27 | 1 |
| 40 | 1 |
From the table we know that 25 occurs maximum number of times so the mode is 25.
