Question

Which of the following terms is mismatched with its example?

a. Bias- Cases tend to have a better recall on past exposures than controls
b. Bias- Spring balance shows variation in measurement due to fluctuations in room temperature
c. Confounding- Study evaluating association between exposure and outcome is skewed by third variable that predicts outcome and is also associated with the exposure
d. Random Error- You measure the mass of a ring three times using the same balance and get slightly different values

Answer 1

B

b. Bias- Spring balance shows variation in measurement due to fluctuations in room temperature

The above is mismatch

It's suppose to be random error-Spring balance shows variation in measurement due to fluctuations in room temperature
