2. An abstract – directly following the title page. It is fine to simply write “Abstract” at the top of the page then give the abstract as a paragraph below. Follow the link below for some guideline on how to write a good abstract – Abstract (Links to an external site.) 3. The introduction – In the introduction you explain the basic idea of the relationship between the variables. This part usually requires some research. You need, for example, to give a brief historical overview of the big bang theory. Where did it come from and why was Einstein so opposed to it? Why did Einstein refer to the “cosmological constant” as his “biggest blunder?” In the introduction you should explain what we would expect to see for the slope of the regression line if the universe is actually expanding. Ultimately the introduction should culminate in a statistical hypothesis about beta, the true slope of the best fit line. 4. Results section – In this section you give the scatter plots and other statistics such as the p-value and coefficient of determination. The results section should contain interpretations and explanations. What does the pattern in the scatter plot reveal about possible relationships between the variables?
