For example, the number exactly halfway between 5 and 10 is: The Midpoint Formula works exactly the same way. Flag those over 100% and those in negative and investigate why they are in that situation. Suppose that the midpoint (hypothesized mean) is at 3.8 and the right endpoint (sample mean) is at 5.1. You can toggle back and forth between having the file calculate your range spread/midpoint differentials, or entering the range spread and differential percentages, and having the file calculate the min-mid-max amounts. Thus, we have four terms in our sum. That's a one pound bag of grass seed! I am not sure how to find the distance between two points. Simply defined; A median is a number that is between two numbers which is exactly halfway, like for example; the median of 3 and 5 is 4 (There are many numbers between 3 and 5but 4 is the median because the difference between 3 and 4 is the same as the difference between 4 and 5) So if you take on the number line, the median of 3 and 5 must be equidistant from both 3 and 5. The most important thing about finding the midpoint is that the addition of the two numbers must occur before the division by 2. Hey Sal, isn't the midpoint formula (x1 +x2 / 2), (y1 + y2 / 2?).
