I am conducting an online experiment, in which I have five page blocks that I want to put in random order for each participant. Even though I used the random generator, wrote the PHP code and clicked 'drawing without putting back' (and said to draw 5 times), it still only draws four of the blocks instead of five.
I'm somewhat desperate because I feel like I tried everything, nothing seems to work. I'd very much appreciate an answer or any tips and tricks! Thanks :)
