1. Experimental method allows researchers to have control over the variables of which they are studying. Researchers introduce a new change to whatever they are studying and monitor the effects it may have. Researchers are basically looking at cause and effect, looking at different influences on the variable. There are two different variables the dependent and independent. An example of an experimental study could be like in the video the effects of eating fast food and weight gain. The dependent variable would be gaining weight and the independent variable would be the amount of fast food you eat. So in the study you can change the independent variable like the amount of fast food you eat in a day or in a week. If the dependent variable changes depending on the independent, you can see the effect of the fast food having on your body.
In correlational methods, researchers are only looking at the relationship between variables without manipulation. Researchers are looking at natural occurring variables. Researches measure two or more variables and determine if one is related to the other.

Correlational may be useful because it lets you clearly see any relationships between variables, and may be used if an experiment would be unethical. For instance, you can not hire test subjects to smoke a pack of cigarettes a day but you can study people that may already smoke. You can study variables outside of the lab, there are many different variables at play, and you can collect information from many subjects. Like if you are doing an experiment on the effects of smoking and cancer, you will be able to find many test subjects that smoke at a higher or lower amount a day. There are disadvantages like self-report errors, only provides a relationship without showing why. For example, you can see the relationship of between low IQ and delinquency but there is no reason
