Repeat loop if less than 75% correct

  Hi,

  The best way to achieve this is by setting the repeat value very high, so that the loop is de facto infinite. And then you can use the following break-if statement:

  [acc] > 75
  

  You'll probably also want to disable 'Evaluate on first cycle', so that at least one cycle is executed.

  This will break the loop as soon as the participant reaches more than 75% accuracy. If you also want to specify a minimum number of cycles, then you can make use of the live_row variable, which indicates the current row from the loop table. For example:

  [acc] > 75 and [live_row] > 10
  

  Does that clear things up?

  I am still confused. I want the cycle to repeat 1.5 times randomly anyways. Then if out of those 1.5 times if there is less than 75% accuracy, I want it to repeat the whole loop over again.

  Right, I see. In that case, you can add another loop + sequence above the loop that you want to repeat. Here I've called these repeat_loop and repeat_sequence. Their only function is to repeat the inner loop (block_loop), using a repeat_cycle item, until accuracy is 75% or higher.

  Does that make sense? I've attached a simple demonstration experiment.
