Answer:
Median = 102
Step-by-step explanation:
To find the median we will following the steps below;
study the numbers, if they are not arrange from ascending to descending order, you try to do that.
87,98,106,82,111,120
82, 87, 98,106, 111, 120
Pick the middle number, if there is just one number that falls in the middle, that number is your median, but if there two numbers that falls in the middle, you add the two numbers and then divide by 2.
In this case, two numbers falls in the middle, so we will add and divide by 2
That is;
Median = 98 + 106 /2
=204 /2
=102
Median = 102
