Describe the sampling method used in this study The primary objective of conducting research is the ability to come to a conclusion in regard to the entire population from results obtained through sampling. The sampling method used in this study is the simple random sampling. The random sampling method is a sampling procedure that ensures each element in the population will have an equal chance of being included (Zikmund, Babin, Carr, & Griffin, 2013, p. 396).

The one types of non-probability sampling methods is convenience sampling. Convenience sampling occurs when data collection is obtained from the easiest to get hold of subjects.

Therefore, we can weakly state that as social pressure by friends and other important figures increases, exercise frequency also increases. However, we cannot draw the conclusion that social pressure truly causes an increase in the frequency of exercise. Running different statistical tests or utilizing the experiment method would have allowed us to draw a causal claim. Future researchers in this field may want to consider this in order to better design their study. Furthermore, we utilized…
