Researchers have to deal with a few tough problems when they use randomization methods in real-life situations. Here are the main challenges:
Practical Difficulties: Putting randomization into action can be tricky. For example, in schools, if students are randomly placed in different classrooms, it might mess up their friendships and social groups.
Ethical Issues: Randomly assigning treatments can lead to serious ethical questions, especially in healthcare. If one group gets a helpful treatment while another group does not, it can create a lot of problems.
Following the Rules: It can be hard to make sure that participants stick to the random assignments. For instance, in a medical study, if patients like one treatment better than the other, it could affect the results and create bias.
All of these challenges mean that researchers need to think carefully and be creative when designing their studies.
