Getting ready for your BCBA exam? You’re in the right place.

I created RBTExamPrep.com to give you the most realistic BCBA mock exam experience possible 185 questions designed to feel just like the real thing.

My goal isn’t just to help you pass, but to help you understand every concept deeply.
Whether you get a question right or wrong, you’ll see detailed feedback explaining why, so you’ll be ready for that type next time. I want you to walk into test day feeling confident, calm, and prepared.

Many students have shared that these questions felt almost identical to the real exam and that’s exactly what I was aiming for. I’d love to hear how you did please share your score in the comments below! It really helps encourage others who are preparing for the exam. 🙂

I built this site to keep high-quality BCBA prep resources free and accessible for everyone, which is why it’s supported by ads. If it helped you, it’d mean a lot if you shared it with your peers.

If you want to keep practicing, check out the BCBA section for more tests and study materials!

 

Results

#1. In the context of experimental design and hypothesis testing in behavior analytic research, a researcher conducts a study to evaluate the effectiveness of a new intervention for reducing self-injurious behavior. After analyzing the data, the researcher concludes that the intervention did not have a significant effect, even though, in reality, the intervention is truly effective. This specific error in the researcher’s conclusion is formally known as a what?

A) False positive

B) Type I error

C) False negative

D) Replication failure

A Type II error also known as a false negative occurs when a researcher fails to detect a true effect that is they incorrectly conclude that there is no significant difference or effect when one actually exists in reality The text explicitly states a type 2 error is going to be a false negative In the given scenario the intervention is truly effective but the researcher concluded it was not which perfectly aligns with the definition of a Type II error or false negative A Type I error also known as a false positive occurs when a researcher incorrectly concludes that there is a significant effect when in reality there is none Replication failure refers to the inability to reproduce the results of a previous study
