    Experiments involve making a prediction and gathering data. There are two sorts of experiments:


    Natural experiments 

    These are where variables are not controlled. These are a good research method if a researcher would like to understand the environment without interference. However, this research cannot prove causation.  

    Example: Tracking a dog’s activity throughout the day to understand how they spend their time alone. 


    Controlled experiments

    These involve comparing an experimental group with a control group. These two groups are identical except for one variable. 

    Controlled experiments are a good research method to establish cause and effect. These also follow a specific procedure, which makes it easier for another researcher to replicate the study. 

    Example: Studying to rock music, heavy metal, classical music, and jazz to understand the way each of these genres impact on concentration.
