Question

would it make sense to say this is a correlational study because variables were not manipulated and used to measure variables that exist naturally?

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Introduction

There are two types of study involve in the survey, they are correlation and experimental study. Experimental study is the cause and effect study. It tells the relationship between the independent and dependent variable. Correlation study is used to make association between the two variables.
