Averages from Frequency Tables
The below QuickQuestion Interface © generates 10 random frequency tables for which you must work out the average.
Choose the size of the first number in the table, and how many rows you want in the table.
For each of these make the minimum and maximum possible the same if you want a fixed amount.
Choose which averages you would like to have questions about. If you choose "All Together" the question will ask for all four bits of information at the same time.
Decide on what types of tables you would like, and if grouped give the allowable sizes of the groups.
Finally, if you would like a specific label for the data, type it in. If this is blank, a random one will be used.
You can then type in your answer or simply reveal the correct answer.
If you have All Together, separate each average with a semicolon ;
With the questions generated, type your answers in the box, and once finished click "Check Answers".

Ideas for Teachers
This is a good alternative to the QQI activity, if you just want to put 10 questions on the board. Then you can get answers from students to enter in the boxes before checking them, and correcting as necessary.
However, the real power in this activity is when you get the students using it themselves. In a computer lesson, set them all going on the activity, and get them to repeat until they get every question correct.
Or you can set it as a homework, telling them the conditions to use (different conditions for different students to differentiate the homework). Then get them to do one or two sets, all correct, and to take a screen shot and either email it to you, or, even better, stick it in their books. Since the questions are random, every student will get a different set of questions, and the immediate feedback means they can go back and correct their work straight away.
