In fact, if you immediately notice that a question is a biostats question you may want to skip to the end of the question and not even read the first few sentences. It is not a huge time saver, but every little bit counts for an 8 hour exam.

If you are going to save a few seconds by skipping over the paragraph long question, I suggest you spend that extra time on double checking your work and avoiding dumb math error for any questions that require calculations.

This is a VERY long test! Your brain will be fried by the end of the exam so making really dumb math error is much more likely. I suggest writing out the formula for each question and double checking your math to avoid dumb mistakes. You will be provided a small erasable board during the exam where you can take these notes.

I also use the calculator built into the testing program for even basic calculations. Thankfully you do have some room for error here.

The answers for biostatistics or epidemiology questions with calculations are usually pretty far apart. You will never see a list of answers that looks like this; Forget about fretting over those significant figures like in undergrad!

Sometimes they will choose their answers specifically to trip you up. For example, if the question is asking for sensitivity and you accidentally calculate specificity, the answer you got may be listed. They know it possible for people to accidentally confuse the formula for similar items like specificity and sensitivity, so they want to make sure their questions differentiate between the two concepts to make sure you really know the difference.

Sometimes they make you calculate the final answer yourself. Other times they list a formula that is one or two steps before the final answer.

However, this can sometimes backfire since there are numerous different ways to find any given answer. You just did your math a bit differently than the person who wrote the answers for the question.USMLE Biostatistics and Epidemiology: USMLE Self Assessment Series - Kindle edition by Tom Heston MD.

Mean (the average) is the sum of all values divided by the total # of values • Unlike median and mode, it is very sensitive to extreme scores • Therefore NOT good for measuring skewed distributions • Repeated samples drawn from the same population will tend to have very similar means • Therefore the mean is the measure of central tendency that BEST.
