Answer:
B) Mode doesn't change.
Step-by-step explanation:
Given:
A set of data with 16 being added to the set.
The mode of a given set of data is the data that is repeated the most number of times.
Here, 19 is repeated 3 times, so the mode is 19.
Now, if a number other than that of 19 being added, doesn't affect the mode of the data set as 19 will still be 3 times and adding 16 will not increase its number in the set.
So, the correct option is B.
