Part I: Using the Correlational Method

Translation of the proverb into a testable hypothesis
“Birds of a feather flock together.” The meaning of this proverb is that people who share similar interests tend to hang out more with one another than those with different interests. In other words, if given a choice, people would automatically spend more of their time associating with other people of the same interests. In testing this hypothesis, a survey will be conducted to see the correlation between the predictor variable-- how often the participants attended group activities--and the criterion variable--how much time they spent together in their spare time. The spare time is defined as the time outside of the group activities.
The survey is as follows:

This questionnaire is to see if church is a big part of your life.
0 1 2 3 4 5 6 7 8 9 10
Not at all Average A lot
Are you Christian?
Using the scale above, answer the following questions:
If yes, how often do you attend your Christian fellowship activities?
In your spare time, how often do you spend time with the people in your Christian fellowship?

Selection of an appropriate subject population
The survey is to be conducted on Bruin Walk of the UCLA campus and the participants are the first 100 people seen hanging around the information tables set up for Christian fellowship groups. There is no anticipated risk involved in conducting this survey. The participants are told that it is a church-conducted survey to get a general consensus of how big of a role Christianity plays in their lives.

Predictions and/or expected results
In maintaining consistency with the hypothesis, a positive correlation is obtained between the predictor and criterion variables. The more the participants attended the Christian group activities, the more time they tend to spend with people of the same fellowship outside of the planned group activities. That is to say, the participants spent more time with people of their same interests than not.

Part II: Using the Experimental Method

Translation of the proverb into a testable hypothesis
Similar to the correlational method, the proverb “Birds of a feather flock together” holds the same meaning. Except in this case, the independent variable, which is the manipulated variable, contains two levels and is measured by the type of video. The dependent variable to be measured, as a result of the independent variable, is the number of people that watched the video.
In this experiment, the manipulated variable will be the type of video, whether it is a cartoon or drama. The participants will be placed in one room containing a television, VCR, one video, as well as board games and such to occupy their time. For the first 2 hours in conducting this experiment, a drama will be shown and the participants are given the choice to either play with the games or watch the video. Those who decide to watch the video are then asked to write on a piece of paper their age. Then for the next 2 hours the cartoon will be shown, and again the participants may choose to watch it or play games. The participants watching the video are asked to write their age on a piece of paper as well. The ages of the participants and the type of video they watched are then recorded. The independent variable is the only thing that is changing in this experiment.

Control procedures
To control for people, who would have difficulties in watching or understanding a video in English, the participants picked would be educated to some degree, whether at the elementary or college level. The participants were all placed in one room so they were all exposed to the same things and it was only by their own will did they choose to either watch or not watch the video. Hence, they were not encouraged to do anything unless it was something of interest to them. The games and such provided in the room aside from the television and VCR were suitable for people of all ages. This prevented the possibility that a participant would resort to watching the video because the games were not up to par with their age.

Selection of an appropriate subject population
The participants in this experiment will be taken from two separate locations. Fifty of them will be randomly taken from the UCLA campus and the other
