Question
When mode is indeterminable?
✓

Answer

In case of bimodal series or multimodal series, mode is indeterminate.
For example, A marathon race was completed by 5 participants. What is the mode of these times given in hours? 2.7hr, 8.3hr, 3.5hr, 5.1hr, 4.9 hr Ordering the data from least to greatest, we get:
2.7, 3.5, 4.9, 5.1, 8.3
Since each value occurs only once in the data set, there is no mode for this set of data.
