Please review carefully about the instruction from the attached file, there should be include a graph, Building the lit review, forming a hypothesis, writing the introduction and writing your hypothesis (that you will be turning in both the analysis,graphs of the first part and the literature review,hypthesis of the second half)
Step 1 (familiarizing yourself with the background). Our starting point is a study by Willerman et al (1991) that is summarized at this site
Fill these tables in until you have all 20 men listed under the Male column and all 20 women in the Female column.
Once you have complete tables, calculate a Pearson correlation coefficient (r) for each. You should obtain positive correlations for both groups. Graph each as a scattergram so that you can see the trends. To find out it your r-value is statistically significant you simply go to Table E (Critical values of Pearson r) in the back of the book. You then go to the column on the left and go down to the number of your subjects minus 2. For example, if there were 20 people in the correlation study, you go to row labeled 18. If you have a number of subjects like 55 (not in the table), use the closest one that is smaller–50 in this case.
Next, you go across to the second column of 4-digit numbers–with the heading \”.05\” under \”two-tailed test\”. If the value of your calculated r is greater than the table value, it is significant. Significance mean that the r-value is big enough that we do not think it could have happened just by luck.
Ifyour calculated value is smaller than the table value, then it is non-significant. This does not mean that it is not possibly real and good, but only that we cannot be sure that it wasn\’t just due to luck.
NOTE. The r-calculations and graphs should be turned in with the exercise.
Step 2 (Building the lit review)
pick a research question to use as a follow-up to the Willerman study. Ultimately, you will construct your own hypothesis, generate data, and come to a conclusion from your simulated study. You should come away from this step with a collection of articles (like you did in exercise 1) all relating to the particular research question you would like to work with. You will use these to write the introduction to your paper and form the background for your hypothesis
Step 3 (forming a hypothesis)
all you need to do is come up with a logical study looking at the correlation of two variables in the general area of brain size and intelligence. The only requirements are that it have something new in it and that it be logically based on the studies you have examined. Rather than straining your brain to come up with something out of the blue, it is much easier if you can find a starting point that is interesting to you; then an idea will often pop into your head as you are reading an article.
Step 4 (writing the introduction). The introduction section of a research paper is basically a review of the literature that leads up to your hypothesiswhich you will state at the end of this section. Clear writing and a logical order are two essential qualities to a good Introduction.
Step 5 (writing your hypothesis).
As you work your way through an introduction you should be building logically towards some hypothesis. You have explained how previous researchers have found this particular finding and have found that particular finding. You have explained how certain questions arise from this previous work. Now, you need to say which of the various questions is the one you are going to pursue.
at the end of your Introduction you should state your hypothesis clearly. Use words along the line of The purpose of this study was to … Follow an explanation of what you plan to do with another little statement along the line of It is expected that the results will show that ..
