Question
The mean of a dataset is 10. If all values are increased by 5, what is the new mean?a.5b.10c.15d.20
Solution
The new mean would be 15. When all values in a dataset are increased by a constant, the mean will increase by the same constant. So, if the original mean was 10, adding 5 to all values in the dataset will increase the mean to 15. Therefore, the answer is c. 15.
