Ans. Mode is the value which occurs the most in a list. From the above data, we can see that the 20 rupees note has the
highest number. So, the mode is 20.
7. Find the median of the following vales:
12, 110, 18, 12, 15, 19, 13, 12, 110, 115, 17
Ans. Arranging the data in ascending order:
12 12 12 13 15 17 18 19 110 110 115
th
Median = n+1 item n=11

8. Create a frequency table for the following:
12 5 4 3 8 9 12 9 8 7
6 71 12 30 2 5 4 3 71 8
7 12 9 6 4 2 1 71 22 3
22 12 8 9 5 12 4 3 12 71
Ans. 12 5 4 3 8 9 12 9 8 7
6 71 12 30 2 5 4 3 71 8
7 12 9 6 4 2 1 71 22 3
22 12 8 9 5 12 4 3 12 71
