ANSWER
True
Step-by-step explanation
The mode of a data set refers to the most occurring number.
In other words, the mode is the number with the highest frequency.
So if a given data set has none of the numbers occurring most, then the data set has no mode.
The following data set has no mode.
{2,3,47,14,7}
Hence it is true that, a set of data can have no mode.
