APA Paper Statistics

Throughout this assignment I have grown more familiar with APA Format and Google Docs.
  • I have become more familiar with the upload process.
  • I have learned that sometimes information or formatting can be lost in the transfer from Excel to Google Docs.
  • I have also learned more about the process of publishing documents in Google Docs as webpages.
The primary objective in APA Formatting when using charts and graphs, is to determine their necessity, and make them as clear and concise as possible while still representing the information. I also learned how to properly format references in APA, create a neatly formatted title page, and display page numbers throughout my document.

To analyze the statistics and create the charts within my paper, I used functions of Microsoft Excel.

The anaylsis toolpach allowed me to run TTests on my data:

To evaluate whether or not there is a significant difference between sets of data, one must look at theP(T<=t) values. If they are < 0.05 the data is signicantly different. If P(T<=t) > 0.05, then the data is not dignificantly different. Thus, the data analyzed below is significantly different.
