Answer: Median = 74
===================================================
Step-by-step explanation:
Given set = {68, 74, 82, 75, 70}
Sorted set = {68, 70, 74, 75, 82}
The median is the middle-most value, which in this case is 74. We can see this if we cross off the outer pair of values to get the smaller set {70,74,75}, though this step is unnecessary considering the original set is only 5 items.
Side note: if there are two items tied for the middle, then take the midpoint of them. The midpoint formula is (a+b)/2. So you add the values and divide in half.
