What are the mean, median, and mode of the following numbers?: 42, 19, 36, 9, 42, 17, 3, 6, 9, 42, 11, 22, 16, and 14
Mean: 19.86; Median: 16.5; mode: 42.
To calculate mean you have to sum all the numbers and divide the sum by the quantity of all numbers.
Median of an ordered set of numbers is the center number if the quantity is odd, or the mean of 2 cennter numbers if the quantity is even. So the first step to calculate median is to order the data set.
Mode of the data set is a value (or set of values) which have the most occurences in the set. For example:
1) The set 1,1,2,3,3,3,5,6,8,8,8,10 has 2 mdes (3 and 8) because these numbers have the same number of occurences and it is the highest number.
