Research Methods: Experimental vs Correlational

This study aims to find a relationship between two variables (caffeine consumption and sleep quality) without manipulating them. There's no manipulation of variables; instead, the focus is on understanding the association between them.

• Experimental

• Correlational

This study involves testing the impact of a stress reduction technique (independent variable) on anxiety levels (dependent variable). The researcher manipulates the use of the stress reduction technique to observe its effects, making it an experimental study.

• Experimental

• Correlational

This study aims to determine if there's a relationship between the hours spent exercising and body weight. It does not involve manipulating the exercise hours; rather, it looks at the association between these two variables.

• Experimental

• Correlational

This study involves manipulating the use of a specific study technique to observe its effect on exam scores. Participants are divided into groups to test the impact of the technique, making it an experimental study.

• Experimental

• Correlational

This study aims to investigate the relationship between social media use and self-esteem without altering either variable. It looks at the association between these two variables without manipulating them.

• Experimental

• Correlational

This study involves manipulating a variable (music tempo) to observe its impact on mood. Participants might be exposed to different music tempos, and their mood changes are measured, making it an experimental study.

• Experimental

• Correlational

This study involves manipulating the music tempo of a song to observe its impact on mood. Participants might be exposed to different music tempos, and their mood changes are measured, making it an experimental study. In this study which is the independent variable?

• Volume of Music

• Mood

• Music Taste
