Pearson Product-Moment Correlation - When you should run this test, the range of values the coefficient can take and how to measure strength of association. What does this test do? The Pearson product-moment correlation coefficient (or Pearson correlation coefficient, for short) is a measure of the strength of a linear association between two variables and is denoted by r. Basically, a Pearson product-moment correlation attempts to draw a line of best fit through the data of two variables, and the Pearson correlation coefficient, r, indicates how far away all these data points are to this line of best fit (i.e., how well the data points fit this new model/line of best fit). What values can the Pearson correlation coefficient take? The Pearson correlation coefficient, r, can take a range of values from +1 to -1. A value of 0 indicates that there is no association between the two variables.

Statistical Power « PreviousHomeNext » There are four interrelated components that influence the conclusions you might reach from a statistical test in a research project. The logic of statistical inference with respect to these components is often difficult to understand and explain. This paper attempts to clarify the four components and describe their interrelationships. The four components are: Complimentary Exam Copies Please read the terms and conditions carefully before completing the form.

Academic Phrasebank – Referring to Sources One of the distinguishing features of academic writing is that it is informed by what is already known, what work has been done before, and/or what ideas and models have already been developed. Thus, in academic texts, writers frequently make reference to other studies and to the work of other authors. It is important that writers guide their readers through this literature. This section of Academic Phrasebank lists some of the phrases that writers may use for this purpose. A note on the literature review: It is the purpose of the literature review section of a paper or dissertation to show the reader, in a systematic way, what is already known about the research topic as a whole, and to outline the key ideas and theories that help us to understand this.

Beginner's guide to R: Introduction R is hot. Whether measured by more than 4,400 add-on packages, the 18,000+ members of LinkedIn's R group or the close to 80 R Meetup groups currently in existence, there can be little doubt that interest in the R statistics language, especially for data analysis, is soaring. Why R? It's free, open source, powerful and highly extensible. "You have a lot of prepackaged stuff that's already available, so you're standing on the shoulders of giants," Google's chief economist told The New York Times back in 2009.

Improving Conclusion Validity « PreviousHomeNext » Improving Conclusion Validity So you may have a problem assuring that you are reaching credible conclusions about relationships in your data. 10 Stats Terms Explained in “Plain English” (#10: Standard Deviation) In the strictest sense, APA style discourages the use of color in graphics, stipulating that it be used only when it is "absolutely necessary". Consequently, most universities and dissertation committees also discourage (or downright forbid) the use of color graphics in dissertation manuscripts. Personally, i find this irritating, as I think most graphical representations of data can be made more clear with the appropriate use of color. However, I suppose the guideline is meant to provide uniformity and consistency across manuscripts, which is understandable. Unfortunately, if you use SPSS you've probably already discovered that it produces graphics in color by default.
