Praxis 5857 Practice Test Practice Question
Which of the following is a rate that has been statistically manipulated (controlled) for certain characteristics?
Correct Answer: D
Rationale: Adjusted rates are calculated to account for certain characteristics, such as age or sex, allowing for a fair comparison across different populations. This manipulation helps to eliminate biases that might skew the data.
Specific rates refer to rates calculated for a specific subgroup without adjustments, while crude rates present raw data without accounting for demographic differences, potentially leading to misleading conclusions. Death rates simply measure the number of deaths in a population, without any statistical adjustments. Thus, adjusted rates provide a clearer, more accurate representation of data by controlling for variables that may affect the outcome.
