formula for finding mean through direct mean method: sigma fi xi /sigma fi
(1,1) is the midpoint between (0,0) and (2,2)
Using a calculator or by trial and error which is 41
Differing from standard deviations, the coded deviation method finds the mean of grouped data from the assumed mean using unit deviations. This is a shorter way to find the mean.
just count the squares and say there are an equal amount of squares?? if a line is bisecting the other line the dot is the midpoint
The formula for finding the mean of grouped data using the coded formula is: Mean = Σ(f * x) / N, where Σ represents the sum, f is the frequency of each class interval, x is the midpoint of each class interval, and N is the total number of observations.

it is fast and easy

The midpoint of a line can be found easily by using the midpoint formula. Find the length of the line and simply divide it in two.
When we compute price elasticity between any two points on a demand curve, we get a different answer depending on which point we choose to start and which point we choose to finish if we take the change in price and quantity as a percent of the starting value for each. With the midpoint method, the percentage changes in quantity and price are calculated by dividing the change in the variable by the average or midpoint value of the two points on the curve, not the starting point on the curve. In other words, it avoids the problem of getting a different answer when we computer price elasticity between any two points on a demand curve and it calculates by dividing the change in the variable by the midpoint value of the two points on the curve instead of the starting point on the curve. That is the advantage of using the midpoint method for calculating elasticity.

The method is too complex to describe here in detail, but the system of hardware and software that implements the method is the Global Positioning System (GPS).
Finding the center of gravity of an irregularly shaped object can be done using the plumb line method.

If you use the "list the multiples" method of finding the LCM, it is likely that the lists and the size of the numbers on the list will increase as the numbers you are comparing get larger. If you learn the "prime factorization" method, you can avoid that.
