Find the mode exists between the odd numbers from 20 to 40.
No-mode
The odd numbers between 20 and 40 are 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39. Each of these values occurs exactly once in the set, so no value repeats more frequently than another. Since no value has a higher frequency, the data set has no mode.
