<u>Answer</u>
c. mean = 75.8, median =76.5, mode = 63
<u>Explanation</u>
Mean, meadian and mode are called the values of central tendancy. The help us study a set of data more clearily.
mean = total value/total frequency
=(88+89+65+62+83+63+84+63+74+64+71+82+66+88+79+60+86+63+93+99+60+85
) ÷ 22
= 1667/22
= 75.8
Median is the value at the center of the data when arranged in ascending order.
60,60,62,<em>63,63,63</em>,64,65,66,71,74,79,82,83,84,85,86,88,88,89,93,99
median = (74 + 79)/2
= 153/2
=76.5
Mode is the value that occurs many times in the data.
Mode = 63
