Hello everybody,

I am currently working on an experiment, where the participant has to multiply two numbers with each other.

The multiplying tasks should be generated randomly. So for each new task there should be two random selections for a number between 2 and 11 and these two numbers make then the multiplying task for the participant.

So for Example 3 *4 , 11 * 10, 5 *5 ,…

I am not sure how to do this. Is it useful to use an excel file for that? If somebody could help me I would be very grateful.

Also the participant should get a feedback afterwords how many % of his responses are currently at the moment. So e.g when the participant answers the first task correctly then the correct responses is 100%, but if he answers the second one incorrect it is only 50% and so on.

I am totally lost how to do this.

Thanks in advance for any help you have!!

Best wishes Sarah
