You can put this solution on YOUR website!
The original set is L1 = {23,34,55,77,56,34,55,80,23}
Sort the values from smallest to largest to get L2 = {23, 23, 34, 34, 55, 55, 56, 77, 80}
Let's make a frequency table for all the values
| Value | Frequency |
|---|
| 23 | 2 | | 34 | 2 | | 55 | 2 | | 56 | 1 | | 77 | 1 | | 80 | 1 |
The largest frequency is 2 and it happens for the values 23, 34 and 55. Therefore the mode is the set {23, 34, 55}
Note: it is possible to have more than one mode which is why I used curly braces to indicate set notation.
