Detailed explanation-1: -There is more than one mode when the highest frequency was observed for more than one value in a data set.
Detailed explanation-2: -There can be more than one mode in a list or set of numbers. Look at this list of numbers: 1, 1, 1, 3, 3, 3. In this list there are two modes, because both 1 and 3 are repeated same number of times. On the other hand, sometimes there is no mode at all.
Detailed explanation-3: -The correct answer is b) Yes, if two or more values in a data set occur the same number of times. This is because the mode is the most repeated value in the data set. If any two values are most repeated and the frequency is the same for both the values, then it is possible for the data set to have more than one mode.
