Post a reply in which you:

1. Respond to your group member’s study idea and state whether you agree or disagree with their study design. What would you change about their study, if you had to change one thing to make it as good as it possibly can be (remember, every study could be improved, even if it's really good to begin with!). 

An experimental study is made to discover whether when spending time with friends causes more happiness, the process would be the effects of time spent with friends to happiness level. This experimental study will consist of two subject groups, one group would be the control group and the other the would be the experimental group. 10 adolescent subjects and paired with their best friend, and the control group of 10 will be paired with strangers.

 

What is your hypothesis? 

 

For the alternative hypothesis, the result would be “a significant result was observed between the level of happiness and the time spent with friends”. The null hypothesis would be no significant change between the level of happiness and friends.

 

 

What is your independent variable? How will you manipulate the IV?

 

The independent variable would be the time the subjects spent with their friends. To manipulate this variable, I could create a day where they spend the whole day together doing whatever they want, this would apply to both groups. The control group would have a day to do whatever they please with a stranger and the experimental group would be paired with a best friend.

 

What is your dependent variable? How will you measure your DV?

 

     The dependent variable for this experiment is the happiness level of the subjects. To be able to measure this, I would make my subjects take a survey to measure their happiness, I would collect data twice for this study before and after the experiment. By using t-test to determine how much of a difference there is between the group who spent more time with strangers or the group who spent more time with their best friends. By using analysis of variance (ANOVA) respectively. This will measure the happiness levels before and after the experiment.
