MEASURES OF CENTRAL TENDENCY
Mean ⇒ average ⇒ the sum of the values divided by the number of
items of data
Median ⇒ the middle value when the data are arranged in numerical
order (if there is an even number of data, find the
average of the two middle numbers)
Mode ⇒ the value that occurs most frequently in the set of data
Range ⇒ the difference between the greatest and the least values in
a set of data
Directions: Find the mean, median, mode and range for each set
of data. Show the sum calculated for the mean, and
show the numbers in order when determining the
median.
