To examine a program for educating hypertensive patients at a community health center about the importance of recording weekly blood pressure results, a researcher conducts a study in which patient blood pressure (which is classified as (a) worse, (b) same, or (c) better) is better after an education intervention and usual care, as compared to only usual care. dependent variable(s): independent variable(s): Match the variable to the type of measurement: Blood pressure: Education + usual care/Usual care:
Understand the Problem
The question is asking to identify the dependent and independent variables in a study related to hypertension education, and to classify the types of measurements for blood pressure and the treatment methods (education + usual care vs. usual care).
Answer
Dependent: Blood pressure status. Independent: Education + usual care vs. usual care only. Both measured nominally.
The dependent variable is blood pressure (classified as worse, same, or better). The independent variables are the interventions (education + usual care and usual care only). Both blood pressure status and the type of intervention are measured on a nominal scale.
Answer for screen readers
The dependent variable is blood pressure (classified as worse, same, or better). The independent variables are the interventions (education + usual care and usual care only). Both blood pressure status and the type of intervention are measured on a nominal scale.
More Information
In this study, the dependent variable signifies the outcomes being measured (blood pressure status), and the independent variables represent the different interventions (type of care). This classification helps researchers understand the effect of interventions on the outcomes of interest.
Tips
A common mistake is confusing dependent and independent variables. Remember, the dependent variable is what you measure, and the independent variable is what you change.
