Question

Comment on the mode of the data set which has all the numbers/objects with two number of repetitions.

• A. It has no mode.
• B. Unimodal data.
• C. Bimodal data.

Answer 1

The correct option is A It has no mode.

If a data set has all the numbers/objects with exactly same number of repetitions then it does not have any mode.
For example, consider the following data set:

11	22	33	12	11
23	12	23	22	33

Arranging the data set in ascending order we get,

11	11	12	12	22
22	23	23	33	33

The frequency table of the corresponding data set is as follows:


Here, all the numbers are repeated exactly 2 times.
Hence, this data set has no mode.
