To find the median we want to arrange data in ascending or desending order and the middle number is the median, if the no.of number are even we won't get middle number then what should we do?
To find the median we want to arrange data in ascending or desending order and the middle number is the median, if the no.of number are even we won't get middle number then what should we do?
let’s look at a data set with 6 values.
(2, 12, 10, 4, 6, 8)
This data set contains 6 values. First, we need to arrange them in order:
(2, 4, 6, 8, 10, 12)
Now, since there is an even number of values, there is no “middle” value. To find the median of 6 numbers (or any even amount) we need the middle two values.
(2, 4, 6, 8, 10, 12)
So for this data set, 6 and 8 are my middle two values.
Now, we have to find the mean of these two numbers.
To find the mean, we have to add the values together: 6 + 8 = 14
Then divide that number by the amount of values: 14 / 2 = 7
So for the data set (2, 4, 6, 8, 10, 12), our median would be 7.
