Printable PDF Guidelines for Writing a Case Study Analysis A case study analysis requires you to investigate a business problem, examine the alternative solutions, and propose the most effective solution using supporting evidence.

Preparing the Case Before you begin writing, follow these guidelines to help you prepare and understand the case study: Read and examine the case thoroughly Take notes, highlight relevant facts, underline key problems.
In psychological research this usually reflects experimental design where the independent variables are multiple levels of some experimental manipulation e. For more detail on data entry consult that guide. The last three examples discuss how to reorganize the data from a standard data frame into one appropriate for within subject analyses.
For this discussion, I assume that appropriate data files have been created in a text editor and saved in a subjects x variables table. One Way Analysis of Variance Example 1: Three levels of drug were administered to 18 subjects. Do descriptive statistics on the groups, and then do a one way analysis of variance.
The first argument is always the dependent variable Alertness. The final argument for aov is the name of the data structure that is being analyzed. Thus, this is a 2X2 design with the factors being Gender and Dosage. Read the data file containing this data.
The asterisk indicates to R that the interaction between the two factors is interesting and should be analyzed. Dosage Dosage Gender a b f The words on this list are of three types: Their recall data by word type is displayed in Appendix III.
Note that there is a single factor Valence with three levels negative, neutral and positive. In addition, there is also a random factor Subject. Create a data file ex3 that contains this data.
Again it is important that each observation appears on an individual line! Note that this is not the standard way of thinking about data. Example 6 will show how to transform data from the standard data table into this form.
The output will look like: Note that the p value for Valence is displayed in exponential notation; this occurs when the p value is extremely low, as it is in this case approximately. Fortunately, R is smart enough to divide up the within-subjects error term properly as long as you specify it in your command.
Appendix V contains the data of an experiment with 18 subjects, 9 males and 9 females. Each subject is given one of three possible dosages of a drug. All subjects are then tested on recall of three types of words positive, negative and neutral using two types of memory tasks cued and free recall.
There are thus 2 between-subjects variables: Gender 2 levels and Dosage 3 levels ; and 2 within-subjects variables: Task 2 levels and Valence 3 levels. Get the data from the file and run the following analysis: In the above example, I have put the within-subjects factors first with the within-subjects error term, followed by the between-subjects factors.
This is not a typical way to enter data. A more typical way found e. We need to "stack" the data to go from the standard input to the form preferred by the analysis of variance. Consider the following analyses of 27 subjects doing a memory study of the effect on recall of two presentation rates and two recall intervals.
Each subject has two replications per condition. The first 8 columns are the raw data, the last 4 columns collapse across replications. The data are found in a file on the personality project server. We then need to create a new data. This seems more complicated than it really is although it is fact somewhat tricky.
It is useful to list the data after the data frame operation to make sure that we did it correctly.As a member, you'll also get unlimited access to over 75, lessons in math, English, science, history, and more.

How to Write a Case Study A case study is an in-depth analysis of a real-life situation or incident, as a way to illustrate content and theory to a real or simulated life situation or both.
