A nurse records temperatures of 36.5°C, 37.0°C, 37.5°C and 38.0°C. What is the range of these readings?
Correct answer: C. 1.5°C
- A. 0.5°C
- B. 1.0°C
- C. 1.5°C
- D. 2.0°C
Explanation
Range is calculated by subtracting the lowest value from the highest value. Therefore, 38.0°C minus 36.5°C equals 1.5°C.

About Epidemiology and Biostatistics
Epidemiology examines the distribution and causes of disease by person, place and time, using measures such as incidence, prevalence, mortality and case-fatality rates. Biostatistics covers data presentation, sampling, averages, variability, probability and interpretation of study results, while distinguishing association from causation.
