PSS Lab – Practice T-tests and Chi Square
This Week’s assignment is to utilize your copy of SPSS to design and create a practice T Test and Chi SquareThe SPSS paper is a 3-4 page paper in APA format (excluding title page, abstract, references and tables/appendices) that reviews t-tests and Chi Square and requires the student to utilize research data to formulate their own t-test/Chi square tables utilizing the SPSS program. This paper should be submitted in Word format and should follow proper APA (7th ed.) guidelines.The assignment should include the following subheadings:
Understanding of Statistical Tests:
Paired Sample T-Test:
Define and explain the concept of a paired sample t-test, including its purpose and when it is appropriate to use.
Describe the assumptions underlying the paired sample t-test, such as normality and independence of observations.
Discuss the formula for calculating the t-value and how it relates to the differences between paired observations.
Chi-Square Test:
Define and explain the concept of a chi-square test, including its purpose and when it is appropriate to use.
Describe the types of data suitable for chi-square tests, such as categorical or nominal data.
Explain the calculation of the chi-square statistic and its interpretation in assessing the association between variables.
2. Data Source Explanation:
In the paper, provide a detailed explanation of where the input data was obtained from. Include information about the dataset’s origin, sample size, data collection methods, and any relevant ethical considerations.
Justify why the chosen dataset is suitable for addressing the research question and conducting the paired sample t-test and chi-square test.
3. Analysis and Interpretation:
Use SPSS to create a file to enter raw data from an article similar to the project you wish to emulate. Perform a paired sample t-test to examine differences between paired observations and a chi-square test to explore associations between categorical variables. This should be created using SPSS and reflect a datafile demonstrating your work to create the table and enter data.
Interpret and explain the output generated by SPSS for both analyses, focusing on statistical significance and implications for the research question.
4. Submission: Submit the written paper, SPSS syntax file, and any output files.By incorporating an explanation of data sources into the assignment, students will not only demonstrate their proficiency in statistical analysis but also their ability to critically evaluate and justify the use of data in healthcare/nursing research
