Listed Averages
The below QuickQuestion Interface © generates random lists of numbers for which you must work out the average.
First you choose the size of the numbers you want to work with.
You can also use negative numbers by selecting the minimum value as a negative number.
Then choose how many numbers you want to be in the lists that appear. Make the minimum and maximum possible the same if you want a fixed amount.
Finally 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.
You can then type in your answer or simply reveal the correct answer.
If typing the answer for multiple modes, separate them by commas. If there is no mode, type "no mode" or "none".
If you have All Together, separate each average with a semicolon ;
There is a 10QQI version of this activity which generates 10 random questions at a time.

Ideas for Teachers
The QQI activities are a great way to get all students working. Put random questions on the board, and then get students to answer them on miniwhiteboards. Once all students have answered, and held up their solutions (with working), reveal the answer to see if they were right. Discuss any misconceptions from the working they have shown, or if they have all got it correct, move on to another question (changing the options to make if more difficult if necessary).
