The marks obtained by 15 students out of a maximum of 25 in a test are given as 13, 11, 16, 15, 18, 12, 13, 14, 10, 22, 15, 21, 20, 17 and 24. Find the product of the modes of this set of data.
195
The modes of the data are the values that occur most frequently. In this case, the modes are 15 (which occurs 3 times) and 13 (which occurs 2 times). Therefore, the product of the modes is: \[ 15 \times 13 = 195 \]
