Re: Mode and Median mess [#permalink]
11 Mar 2013, 13:12

Mode is the number that occur most often in the set of values. In this case, 2, 3 & 4 are mode.

To calculate the median, arrange the set of numbers in ascending order & then: 1) if the set has even numbers take the 2 values in the middle & calculate the mean. 2) if the set has odd numbers, the center value is the median.

Median {-1, 0, 1} No problem, median is 0.

{1, 2, 3, 4} Is median (2+3)/2?

{1, 2, 2, 3, 3, 4} Here? 2, 3 or 2.5?

So misunderstanding can affect a solution. If somebody could make it clear, I'll appreciate it. Thanks!

In this case the medians are.

0. You are correct (2+3)/2 You are correct (2+3)/2 = 2.5 You are almost correct
