The hypothesis for this research states that people who play video games for more than two hours each day are introverted. The study takes into account the correlation research design to prove this hypothesis ( Gabbiadini & Greitemeyer, 2017) . The correlation study is carried out to explain the important human behavior that is likely to associate the levels of introversion among people who play video games for more than two hours each day. The human behavior that is tested in the correlation study is the level of shyness of participants and the hours that are spent in watching video games.
The study involves building relationships among two main variables, which are the number of hours spent playing video games and the levels of shyness ( Wittek et al., 2016) . The independent variable is the time spent while playing video games, while the independent variable is the level of shyness ( Gabbiadini & Greitemeyer, 2017) . This implies that the number of hours that are spent is the criterion variable, where it is used as a measure that influences other variables related to the behavior of participants such as the nervousness. On the other hand, scatter plots and regression lines are used in the prediction of the score on the criterion variable.
Delegate your assignment to our experts and they will do the rest.
A positive correlation between the two variables proves the hypothesis, while a negative correlation between the variables tested disapproves it. For instance, when the numbers of hours spend while playing video games is high, the levels of extroversion depicted by the level of shyness will be high ( Wittek et al., 2016) . On the contrary, if the levels of shyness decrease with the number of hours spent on playing video games, then the hypothesis would have been disapproved ( Gabbiadini & Greitemeyer, 2017) . The final results should, therefore, depict that there are high levels of shyness among participants who are subjected to more than two hours while playing video games.
