Biostatistics: pharmacology practice questions
Biostatistics is a high-yield area on the PEBC, NAPLEX, OPRA and FPGEE exams. Phartoonz has 57 exam-style Biostatistics questions, each written to test the clinical decisions these licensing exams actually reward — mechanism of action, dosing, monitoring parameters, adverse effects, contraindications and patient counseling.
Try the sample questions below to see the style and difficulty, then practice the full set with instant feedback and progress tracking.
Sample questions
Sample 1
A study comparing drug A to placebo determined that the relative risk reduction in all-cause mortality was 0.33. Which of the following statements is correct?
- 1Patients who received drug A were 67% less likely to die compared to patients in the placebo group.
- 2Patients who received drug A were 33% as likely to die as patients in the placebo group.
- 3For every 100 patients who received drug A, 33 fewer died compared to patients in the placebo group.
- 4Patients who received drug A were 33% less likely to die compared to patients in the placebo group.
- 533 patients need to be treated with drug A to prevent one death.
Sample 2
The mean of a group of values is:
- 1The average, calculated by adding up all of the values and dividing by 100.
- 2The product of all the values divided by the number of values.
- 3The value that occurs most frequently in a series of numbers.
- 4The average, calculated by dividing the sum of the values by the number of values.
- 5The value in the middle of the list when the numbers are ordered sequentially.
Sample 3
The median of a group of values is:
- 1The value in the middle of a random group of numbers.
- 2The value in the middle of the list when the numbers are ordered sequentially.
- 3The average, calculated by dividing the sum of a group of values by the number of values.
- 4The value obtained by subtracting the lowest value in the list from the highest value in the list.
- 5The value that occurs most frequently in a group of numbers.
