# Experimental design Assignment at an affordable cost

Instructions

In a Word document:

PART A.   Create a Solomon Four-Group Design experimental study to test the following hypothesis. The first thing you’ll want to do is to identify the independent and dependent variables.

Playing violent video games will cause aggression levels to increase.

1. Provide a chart like the one in the lecture that makes clear what groups you would have and what would be done with each one (create a chart by inserting one into your document or by creating it in Excel and copying/pasting it into your document.)
2. Also, provide in list form the labels for each groups and description of what would happen with each. This second step contains basically the same information as the first step, but the list is an expanded version using a fuller description in words so that I can appropriately assess your understanding.
3. List what the results would need to be with each group in order to support the hypothesis that there is a cause and effect relationship between playing video games and increased aggression levels. NOTE: You’re to use your imagination to make up the results… making up numbers to reflect “scores” or “frequencies” (depending upon which is appropriate) that indicate a cause and effect relationship. Plug the numbers into the appropriate place in the graph)

PART B.   Create a Factorial Design study (might be experimental, quasi- or non-experimental) to test the following hypothesis. The first thing you’ll want to do is to identify the independent and dependent variables. (IMPORTANT NOTE: The Factorial Design is a factorial because it has MORE THAN ONE Independent variable… not just two or more values of a single independent variable, but at least two separate independent variables).

Jurors will render a verdict of guilty or not guilty based on the presence of scientific evidence and the credibility of the eyewitness

Restating the hypothesis in longer form to make sure you understand the prediction and can identify the variables:

Although the presence of scientific evidence and the credibility of the eyewitness may each somewhat influence jurors, it is hypothesized that the two combined will significantly increase ‘guilty’ verdicts.

1.  Provide a chart like the one in the lecture that makes clear what groups you would have and what would be done with each one (create a chart by inserting one into your document or by creating it in Excel and copying/pasting it into your document.)
2. Also, provide in list form the labels for each groups and description of what would happen with each. This second step contains basically the same information as the first step, but the list is an expanded version using a fuller description in words so that I can appropriately assess your understanding.
1. Provide a second copy of your chart and replace the group labels with a made-up result for each group (for example using the chart in the lecture, I would replace ‘fear of crime score’ with an actual made-up score (again, using your imagination) of, like, 20 80  62 and 46.) Hint: here, yours should NOT be a score; it should be a frequency (a percentage measure of your DV).
2. Succinctly interpret those result… what do they mean in relation to the hypothesis?
