find the mode of the data 15,14,19,20,14,15,16,14,15,18,14,19,15,17,15. if the last observation is changed to 14, then find the new mode.
The mode is the number that is repeated more than the others.
* It is possible for a set of data values to have more than one mode.
* If there are two data values that occur most frequently, we say that the set of data values is bimodal.
Here 15 occurs most frequently.
Hence mode = 15
If last observation is changed to 14, it has two mode.
