Statistical analysis for Research data - Capstone academic study

@ShaikhAneesa

Hello, I have thoroughly reviewed the project requirements for the statistical analysis of pre-assessment and post-assessment results using SPSS, including Paired t-test and Wilcoxon signed-rank test for five assessments. Let's chat and discuss it further. To handle your project, I will start with importing the data into SPSS, conduct the necessary statistical tests, and generate graphs to visualize the results. I will then interpret the findings and provide a detailed explanation of the statistical parameters. The deliverables for this project will include a comprehensive analysis report with statistical parameters, graphs illustrating the results, and a clear explanation of the findings. Before signing-off my bid, I would like to ask a question, i.e., would you like to include any specific hypotheses to test during the analysis? Best Regards, Aneesa.

Hi, I can perform the complete SPSS analysis for your five pre-assessment versus post-assessment datasets, using the statistical test appropriate to the distribution and study design. I’ll conduct paired-samples t-tests and Wilcoxon signed-rank tests as appropriate, assess assumptions before selecting the test, and report the relevant statistical parameters, including means, standard deviations, median/IQR where appropriate, test statistics, p-values, confidence intervals, and effect sizes where applicable. I’ll also create clear, publication/thesis-ready graphs and provide concise explanations of what each result means, including both statistically significant and non-significant findings. The analysis will be presented in a way that you can directly use in your research Results section. I have a PhD in Statistics and a BSc degree in Economics and Statistics, with strong experience in SPSS, hypothesis testing, paired data analysis, non-parametric methods, statistical reporting, and research data interpretation. I can work directly from your raw dataset and ensure the analysis is statistically appropriate and reproducible. I’m ready to review the five assessments and begin immediately. Kindly consider me, thank you.

Paired t-tests and Wilcoxon signed-rank tests require proper assumption testing and interpretation—many researchers misapply these without validating normality or handling tied ranks correctly. This capstone needs rigorous statistical execution. SPSS analysis across five assessments will include descriptive statistics, normality testing (Shapiro-Wilk), assumption verification, paired t-test outputs, Wilcoxon signed-rank test alternatives, effect size calculations (Cohen's d), and confidence intervals. Each test will be documented with decision criteria and statistical rationale. Deliverables cover cleaned datasets, SPSS syntax files, comprehensive results tables, publication-ready graphs (histograms, box plots, Q-Q plots), and a detailed interpretation document explaining what each statistical parameter means in context of your research question. Post-assessment vs. pre-assessment comparisons will be presented with effect magnitude and practical significance alongside p-values. Turnitin plagiarism report included. Unlimited revisions until statistical validity is confirmed.

Hi, I got that you are looking for a statistician to perform statistical analysis on research data, comparing pre-assessment and post-assessment results using SPSS for Paired t-test and Wilcoxon signed-rank test. This is what I can help you with, let's chat. My approach is to utilize advanced statistical techniques in SPSS to conduct Paired t-tests and Wilcoxon signed-rank tests accurately. By expertly applying these methods, you will receive comprehensive statistical parameters, insightful graphs, and a detailed explanation of the results. I will ensure that the most challenging aspect, the interpretation of statistical significance between the pre and post-assessment data, is handled with precision. As final deliverables, you will receive detailed statistical reports with graphical representations, highlighting the key findings from the analysis. One thing I'd like to confirm before we start: Do you have a specific format in mind for the presentation of the statistical results? Let's discuss how I can assist you in achieving your research goals. Regards, Imran

Evaluating paired pre-post assessment data requires careful verification of distributional assumptions before selecting between parametric and non-parametric tests. Based in the Netherlands with 15+ years of experience in academic quantitative research and SPSS modeling, I will deliver a comprehensive, publication-ready analysis for your five assessments. - Assumption Testing & Model Selection: Run Shapiro-Wilk normality tests and skewness/kurtosis diagnostics on difference scores to determine whether Paired Samples t-tests or Wilcoxon Signed-Rank tests are statistically justified for each of the 5 measures. - Statistical Modeling & Effect Sizes: Execute the analyses in SPSS, calculating exact p-values, test statistics (t / Z), confidence intervals, and standardized effect sizes (Cohen's d and Wilcoxon r/rank-biserial correlation). - Academic Reporting & Visuals: Format output tables strictly according to APA 7th edition guidelines, accompanied by high-resolution visualization plots (paired line/boxplots) and clear, narrative interpretations ready for your capstone manuscript. Could you share the SPSS (.sav) or Excel data file so I can review the sample size and structure of your 5 assessments right away?

@AzeemCodes7

Hi, I can complete this statistical analysis project for all five of your assessments. My Approach: For each assessment, I will run both a Paired t-test (for normally distributed data) and a Wilcoxon Signed-Rank Test (non-parametric alternative), following standard research methodology. Normality will be checked first using Shapiro-Wilk test to determine which result to report as primary. Deliverables for each of the 5 assessments: Descriptive statistics (Mean, SD, Median, IQR) Paired t-test results (t-statistic, df, p-value, 95% CI) Wilcoxon Signed-Rank Test results (W-statistic, p-value) Effect size (Cohen's d / r) Professional graphs (box plots + bar charts with error bars) Plain English interpretation of each result Final summary report in Word/PDF format Format: Results delivered in Excel + PDF report, formatted for academic/research submission Please share your data file (Excel/CSV) and I can begin immediately.

With 10+ years of experience in scientific research and data analysis, I am well-versed in Python, debugging, scripting, automation, and software engineering. I can efficiently handle this task. For the statistical analysis of your research data, I will review the requirements, update the SPSS Statistics script accurately, test the changes, and ensure the results are clean and maintainable. I am confident in my ability to deliver a high-quality analysis within the provided budget.

Hello, I see the main risk is treating all five pre/post pairs as normally distributed without testing assumptions, which can lead to incorrect use of Paired t-test and misleading conclusions. With small samples or skewed difference distributions, Wilcoxon signed-rank test will be more appropriate and effect sizes and confidence intervals must be reported alongside p values. I have completed multiple academic capstone and institutional evaluations using SPSS, performing Paired t-test and Wilcoxon signed-rank test for repeated measures, and producing publication-ready tables and graphs. Typical outputs I provide include descriptive statistics, Shapiro-Wilk normality tests on difference scores, paired-samples statistics, test results with exact p values, Cohen's d or matched rank-biserial effect sizes, and graphs such as paired boxplots, difference histograms, and Q-Q plots. I work in SPSS for reproducibility and can also supply analysis syntax and an annotated results write-up suitable for inclusion in a thesis. I will begin by importing and cleaning your dataset, verifying pairing and missing data, and running normality checks on each assessment difference; then I will apply Paired t-test where assumptions hold and Wilcoxon signed-rank test where they do not, reporting effect sizes and creating the requested graphs. - Do you have the data in SPSS .sav, Excel, or CSV and are pre/post IDs already matched? - Are there any covariates or subgroup comparisons you want included beyond the five assessments? Looking forward to hearing from you, Christopher
