The average is also called the 'mean' which is the sum of the values divided by the number of values used. It represents the number that all the values in the group would …add up to if they were all the same number. Say you want the average score for 17 students who took your art history exam. You add the 17 individual scores together. Then you divide this sum by 17, the number of scores being averaged. The answer you get is the average, or mean score on the exam. An average may be an integer, a fraction, a mixed number, or a decimal number, and it could be positive, negative, or zero too, if some or all of the items in the group are zero or negative. To calculate the average of a group of numerical items: Add up all the items in the group. Divide the sum by the number of items in the group. The quotient is the average of the group. Another Example: Four students pick apples: one has 3, one has 4, one has 5, and one has 8. To evenly divide the apples, you would find the average (sum/number of values). 3 + 4 + 5 + 8 = 20, divided by 4 students is 20/4 = 5 apples.
Calculating an average is easy. Take the numbers that you need averaged add together and divide by how many you numbers you added together.
That's because averages give us some idea about general tendencies.
Take total times reached base. That's all hits, walks and hit by pitch. Divide that number by the total times they came to the plate which includes at bats, walks, hit by pitc…h, and sacrifice.
its very simple... do you want further details plz click here... http://www.business-analysis-made-easy.com/ What Is Standard Deviation? google…_protectAndRun("render_ads.js::google_render_ad", google_handleError, google_render_ad); To answer the question of what is standard deviation you must refer to the question raised in mean average. The mean or average have little value without some measure of the variability of the data. Standard deviation to the rescue! The Equation The standard deviation equation is: It must be noted that this formula is for the sample and not for the population. If you don't know what this means, don't worry about it. For simple applications it makes little difference. Now that you have seen the formula, let's describe what is happening in simpler terms. The formula is simply finding the average distance each data point is from the dataset mean. The squared numbers is a mathematical way of making all of the distances positive. So here is our measure of a datset: First we find the average of the data points, then we find the average of the distance each data point is from the mean or average of the data. This gives us a good beginning in describing the data within a datset. Summary The question of explaining standard deviation has been addressed herein. It is the average of the distance from the mean of all the data points in the dataset. To see an example of how this parameter is calculated go to Standard Deviation Calculation.

add all the outcome / example 15, 64, 21, 7, 10, 3 = 120. Then divide the sum of all the numbers by the number of numbers/ example, take 120 divided by 6=20. So the average nu…mber out of all the numbers above is 20.

to work out an average you add all the final game scores together and then divide this number by the number of games you added together.
Robert walks from town A to town B, he must pass a hill and a section of a flat road. His speed of walking uphill is 3km/hour, on a flat road is 5km/hour and a downhill is… 6km/per hour. Robert's average speed from town A to town B is 4.2.km/hour. What is his average speed from town B to town A?
Average operating assets is the average amount of liquid assets available. This relies very heavily on cash flow which includes accounts payable and accounts receivable. Sin…ce these numbers fluctuate, the average is the most meaningful working figure.
to find average speed divide the distance traveled by the time it took to travel that distance so for example: what is the average speed of a runner that traveled 10 miles in… 2 hours? 10(distance)/2(time) = 5(speed), so the answer would be 5 miles per hour although they may not have been traveling 5 miles per hour the whole time the average speed they were traveling is 5 miles per hour. also you can find the distance by multiplying the time by the speed. and to find time, multiply speed by distance. (dont forget units will vary for answers) hope this helped :)
Formula for calculating average Contribution margin Average contribution margin = total contribution margin / total number of units
Speed is distance divided by time so pick the section you want to work out the average for, work out how much distance has been traveled in that section and divide it by h…ow much time has passed for that section.
