The mean is calculated by adding all the book readings together and dividing by the total number of parents. However, the two parents who reported reading over 30 books per week can skew the mean to make it seem like the average number of books read per week is higher than it actually is for the majority of the class. Therefore, the median or mode would be a better measure of central tendency in this case.
