Objective data (e.g. blood pressure readings) are more prone to recall bias compared to subjective data (e.g., semi-structured interviews) and thus is a bigger threat to the internal validity of a study.

False

Recall bias is a type of information bias where systematic error is occurs due to respondants inability to recall the past events accurately. It is a problem in studies that uses subjective data or self reporting. Example: case control study and retrospective cohort study. It is a big threat to the internal validity of the study. It is also known as reporting bias or responders bias.

In objective data collection like blood pressure monitoring another type of information bias is occurs, called observer bias, where the researcher sees what he wants to see. It is also a threat to internal validity of the study.

Systolic blood pressure readings for females are normally distributed with a mean of 125 and a standard deviation of 10.34. If 60 females are randomly selected then find the probability that their mean systolic blood pressure is between 122 and 126. Give your answer to four decimal places.
