Data Analysis Worksheet – Correlations

(my field of study is general psychology)
Throughout the course, you have been exploring various concepts and building your skills in statistical analysis. This week, you will complete a data analysis report to analyze correlation between assigned variables.
Exploring the associations between some variables in the courseroom using correlations might provide some important information about learner success. You’ll need to pay attention to both magnitude, which is the strength of the association, and directionality, which is the direction (positive or negative) of the association. During this assignment, you’ll start learning about how to best approach correlational analyses like these and start getting some answers. You’ll explore the relationships that may or may not exist in your courseroom data.
In this assignment, you’ll get a chance to run and interpret an inferential statistics analysis: correlations. Your readings and the Course Study Guide [PDF] Download Course Study Guide [PDF]will help you in your efforts.

Instructions
You will complete this assignment using the Data Analysis and Application Template [DOC] Download Data Analysis and Application Template [DOC](also known as the DAA Template).
• For help with statistical software, refer to JASP Step-by-Step: Correlations [PDF] Download JASP Step-by-Step: Correlations [PDF].
• For information on the data set, refer to the Data Set Instructions [PDF] Download Data Set Instructions [PDF]file.
• Refer to the Course Study Guide [PDF] Download Course Study Guide [PDF]for information on analyses and interpretation.
The Grades [JASP] file is a sample data set. The data represent a teacher’s recording of student demographics and performance on quizzes and a final exam across three sections of the course. Each section consists of 35 students (N = 105). There are 21 variables in the Grades [JASP].
This assignment is on correlations. You will analyze the following variables in the Grades [JASP] data set:
Variable Definition
Quiz 1 Quiz 1: number of correct answers
GPA Previous grade point average
Total Total number of points earned in class
Final Final exam: number of correct answers
Variables and Definitions
The DAA Template has five sections:
• The Data Analysis Plan.
• Testing Assumptions.
• Results and Interpretation.
• Statistical Conclusions.
• Application.
Step 1: The Data Analysis Plan
In Step 1:
• Name the four variables used in this analysis and whether they are categorical or continuous.
• State a research question, null hypothesis, and alternate hypothesis for one X-Y pair. For example, you could articulate a research question, null hypothesis, and alternate hypothesis for quiz1 (X) and final (Y).
Step 2: Testing Assumptions
Test for one of the assumptions of correlation-normality.
• Create a descriptive statistics table to assess normality. This table should include the four variables named above.
• Paste the table in the DAA Template.
• Interpret the skewness and kurtosis values and how you determined whether the assumption of normality was met or violated.
Step 3: Results and Interpretation
In Step 3:
• Paste the output of the intercorrelation matrix for all specified variables:
o First, report the lowest magnitude correlation in the intercorrelation matrix, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Specify whether or not to reject the null hypothesis for this correlation.
o Second, report the highest magnitude correlation in the intercorrelation matrix, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Specify whether or not to reject the null hypothesis for this correlation.
o Third, report the correlation between GPA and final, including degrees of freedom, correlation coefficient, p value, and effect size.
•
o Interpret the effect size. Analyze the correlation in terms of the null hypothesis.
• Interpret statistical results against the null hypothesis, and state whether it is accepted or rejected.
Step 4: Statistical Conclusions
In Step 4:
• Provide a brief summary of your analysis and the conclusions drawn.
• Analyze the limitations of the statistical test.
• Provide any possible alternate explanations for the findings and potential areas for future exploration.
Step 5: Application
In Step 5:
• Analyze how you might use correlations in your field of study.
• Name an independent variable and a dependent variable that would work for such an analysis and why studying it may be important to the field or practice.
Submit your completed DAA Template as an attached Word document in the assignment area.
Software
In this course, you will be using the following statistical software.
• Jeffreys’s Amazing Statistics Program (JASP)Links to an external site..
Refer to the Tools and Software: JASPLinks to an external site. page on Campus for general information.
Make sure that your statistical software is downloaded, installed, and running properly on your computer.
Competencies Measured
By successfully completing this assignment, you will demonstrate your proficiency in the following course competencies and scoring guide criteria:
• Competency 3: Evaluate confidence and significance of statistical data.
o Name the variables and include the scale of measurement. State the research question and null and alternate hypothesis, with no more than one error.
o Communicate the assumptions associated with the primary inferential statistic and how they were tested. Import assumption testing table.
• Competency 4: Apply quantitative analysis to individual, organizational, and social issues.
o Paste the output for main inferential statistic(s) as discussed in the instructions and interpret the results of the main inferential test, with no more than one error.
o Summarize briefly the analysis and the conclusions drawn. Analyze limitations of the test and provide alternate explanations for findings and potential areas for future exploration, with no more than one error.
o Communicate how research could be applied to one’s own field of study and the value and implications of this analysis to this
o field, with no more than one error.
• Competency 5: Communicate quantitative analysis effectively in a manner consistent with expectations for psychology professionals.
o Convey purpose in an appropriate tone and style, incorporating supporting evidence and adhering to organizational, professional, and scholarly writing standards.
