11. In a list of numbers:
the mode is the number which occurs the most often;
the median is the number which is in the middle of the list when the numbers have been put in order;
the mean is the sum of all the numbers divided by how many numbers there are in the list.
For example, for the list 1, 4, 7, 1, 2,
mode = 1, median = 2, mean = 15/5 = 3
(a) Find the mode, the median, and the mean for the list 8, 5, 2, 16, 6, 5, 7.
mode = _______
median = _______
mean = ______
(c) Write down a list of five whole numbers for which the mode is 9, the median is 4, and the mean is 5.
(d) Write down three different lists, each containing five whole numbers, so that for each list the mode is 1 and the mean is 2.
