IO 6402 Module 1 Assignment 3 Comparing Types of Measurement Updated

Data can come in many forms, but not all data can be accurately analyzed with all statistical techniques. Therefore, it is important to understand the basic types of data before advancing further in your study of statistics.

Consider the four types of data introduced in this module: nominal, ordinal, interval, and ratio. Define each of these data types. Include industrial/organizational (I/O)-related examples of each type of data (i.e., data that might be collected by an industrial/organizational (I/O) professional in a work setting). For each data type, include an article reference and a brief description of the article you chose that incorporated that type of data into its research design.

Compare the four data types and discuss their relative strengths and weaknesses.

Write a 3- to 5-page paper in Microsoft Word format that addresses the items listed above, utilizing a minimum of three scholarly sources. Make sure you employ proper grammar and spelling and apply current APA standards for writing style to your work.

IO 6402 Module 2 Assignment 2 Descriptive Statistics and Industrial Organizational Psychology Updated

Descriptive statistics and graphical data presentations formulate the initial phase of statistical analysis. With these tools, the industrial/organizational (I/O) professional is able to describe the data as well as begin to determine appropriate further statistical analyses that can be used to interpret the data.

Using the University online library resources, select an empirical research article from a volume of The Journal of Applied Psychology published within the last five years:

· Briefly describe the article.

· Identify the descriptive statistics used.

· Describe how the descriptive statistics were presented (graphs, tables, pie charts, etc.).

· Explain how the descriptive statistics added value to the research.

Write a 3- to 5-page paper in a Microsoft Word document that addresses the items listed above. Make sure you employ proper grammar and spelling and apply current APA standards for writing style to your work.

IO 6402 Module 3 Assignment 2 RA 1 t-Tests Updated

Once again, reading about t-test statistics and descriptive statistics is one thing. Actually using software to compute them requires different skill sets. This assignment is designed to give you the opportunity to practice using Microsoft Excel to compute a t-test and to reinforce your learning of computing descriptive statistics from a previous module. A data set has been presented below for you to use to conduct your analyses. The data set represents the scores from five students who were tested on the same material using three different forms of the test.

· Enter the above data into Microsoft Excel.

· Using Microsoft Excel, compute the mean for each test, each student, and the sample overall.

· Using Microsoft Excel, compute the standard deviation for each test, each student, and the sample overall.

· Using Microsoft Excel, create a correlation table for Test 1, Test 2, and Test 3. Interpret the results.

· Conduct a t-test to see if there is a significant difference in scores between Test 1 and Test 2. Interpret the results.

· Include a printout of your Microsoft Excel computations with your paper submission.

· Explain the concepts of central tendency, variance, standard deviation, correlation, and the difference between the means of two groups.

· Include a description of the computations you conducted on the data provided for this assignment and your interpretation of the results of your computations. What do you know about this data set? What is something that you do not yet know about this data?
