Thank you both for helping with this. I'm so glad that you all are here.

In a correlational study, the goal is to examine the relationship between two variables without any manipulation or control over the variables. The study involves measuring two variables and examining their association or correlation. In this type of study, there is only one group of participants, and their characteristics are observed and measured.
To get the answer to this question, you need to understand the basic principles of correlational studies. A correlational study aims to measure and analyze the relationship between two variables, such as height and weight or hours of study and exam scores. The main idea is to see if one variable changes when the other changes. For example, if there is a positive correlation between hours of study and exam scores, it means that as the number of study hours increases, the exam scores also tend to increase.
In this question, the correct answer is d. because a correlational study involves measuring two variables and examining their relationship without any manipulation or control over the variables. Additionally, there is only one group of participants in a correlational study since no groups are being compared.
