What shows up to participants?
Why Goal/Minimum and Maximum
In most cases, your recruitment goal (or minimum) will be the same as your maximum. You might have a limited financial reward budget, a limited number of study appointments – or some other limited resource that requires you to cap the number of participants at exactly what you need.
However, if you have no resource limits, you might be included to increase your maximum to get more data to create stronger and more nuanced findings. If you think your study is going to attract lots of participant interest, you may consider this.
If your study is being sponsored by a government agency or some foundations – they may request a cap on the number of participants in your study in order to reduce participant burden.
