Averages Calculator
- Need to know the average of a set of numbers? Need to know how those averages were worked out?
- This App not only tells you the answers but also tells you how to work out those answers.
- Great for a study aid. Don't be restricted to a few examples in the book, try out your own and see why the answers are what they are.
The small thumbnail images below will show larger iPad screenshots.
FAQ: This App does not work properly it keeps on crashing, why?
Sometimes Apps just do not download properly. You will need to download it again, for free, using itunes. See Apple Support Pages
About half way down the page there's a set of instructions that starts 'Reinstall the affected application'.
Once iTunes has it then you sync your device and it should then work. If it does not then please to contact me.
When the Application StartsThis is the main screen of the App. At the top is the area where you type in the numbers that are the distribution. To type in the numbers just select the field and the keyboard will be shown. A distribution of numbers is entered by typing in each number separated by a space. The space is the bottom left hand key with nothing in it. Once you have typed in all the numbers you want then select 'OK'. The keyboard will disappear and answers will be displayed below. The answers given are: The arithmetic mean (the value most people mean when they talk about the average), one of three mode values, the median, the geometric mean and the arithmetic mean. |
The Workings PageThis page shows you how each of the answers was calculated. It is this page that will help you to understand the various values. The rows in blue are general explanation information and the rows with white backgrounds explain using the information provided so that the explanations can be directly related to the information. |
The keyboardThe keyboard provides the means to add all the numbers required into the field at the top of the main screen. Each number must be separated using a space (the bottom left empty button). When all the numbers have been entered then you select 'OK' and the answers are calculated. |
