Find the mode(s) for the given sample data. The lengths (in inches) of each snake in the Clarmont Zoo's reptile house are shown
Contact [7]

The correct option is :   no mode

<u><em>Explanation</em></u>

The given data set is:  9, 15, 86, 13, 16, 101, 85, 10, 14, 17, 102

The <u>mode is the number that is repeated more often</u> than any other number in the data set.

So, there will be 'no mode' in this set.
