Data Analysis. For this discussion, you will organize data sets into meaningful number groupings, calculate basic descriptive values, and communicate written critiques of statistical analyses. This exercise requires the use of a descriptive statistics calculator. You can find this tool in some versions of Excel (as part of the Analysis ToolPak) or you can use one of the many free online descriptive calculators such as the Descriptive Statistics Calculator by Calculator Soup. To begin, come up with 20 different data points (that will form a set of data) and enter them into the first column of an Excel spreadsheet. The data points can be any numbers you want as long as there are 20 of them.


You will then use the descriptive statistics option i -----------------------------------

PSY 325 Week 4 Assignment Research Report (2 Papers)

This Tutorial contains 2 Papers of this Assignment

Research Report. Write a research report based on a hypothetical research study. Conducting research and writing a report is common practice for many students and practitioners in any of the behavioral sciences fields. A research report, which is based on scientific method, is typically composed of the different sections listed below: • Introduction: The introduction states a specific hypothesis and how that hypothesis was derived by connecting it to 
previous research. 
 • Methods: The methods section describes the details of how the hypothesis was tested and clarifies why the study was 
conducted in that particular way. 
 • Results: The results section is where the raw uninterpreted data is presented. 
 IV. Discussion: The discussion section is where an argument is presented on whether or not the data supports the hypothesis, the possible implications and limitations of the study, as well as possible future directions for this type of research. Together, these sections should tell the reader what was done, how it was done, and what was learned through the research. You will create a research report based on a hypothetical problem, sample, results, and


literature review. Organize your data by creating meaningful sections within your report. Make sure that you: • Apply key concepts of inferential hypothesis tests. • Interpret the research findings of the study. 
 • Examine the assumptions and limitations of inferential tests.
