Question

Quizplus · Accepted Answer

To calculate the mean of a data set, you need to add all the values together and divide the sum by the number of values. This gives you the average value of the data set. Option B only takes into account the largest and smallest value, which may not be representative of the whole data set. Option C assumes that there are only two values, which may not be the case. Option D only takes into account the two middle values, which may not be appropriate for data sets with odd numbers of values.
