I ran a study, which went nice and quickly. However, I had a few participants who failed multiple attention checks. Some of them indicated they found the attention check a bit confusing, which is supported by the answers to their checks. The majority of participants (90%) have understood and answered the attention checks correctly. Only 10% had an issue with it. I am not sure what to do with their submissions. What would your advice be?
Thank you in advance. I am looking forward to your reply.
