⸻ Project Description: I need a complete statistical analysis project based on engineering student data. The project examines relationships between: * GPA * Credit hours completed * Commuting distance * Number of social media apps * Weekly social media usage ⸻ Scope of Work: 1. Sample Size Calculation * Confidence level: 95% * Margin of error: 0.1 * Standard deviation: 0.51 2. Sample Distribution by Specialization * Industrial Engineering: 23% * Chemical Engineering: 30% * Mechanical Engineering: 22% * Electrical Engineering: 25% 3. Sampling & Data Collection * Random selection of participants * Dataset must include: * GPA * Credit hours * Distance (km) * Number of apps * Weekly usage (hours) 4. Excel Work (Main Analysis) * Sheet 1: raw dataset * Descriptive statistics (overall + by specialization) * Scatter plots for all required variable pairs * Pearson correlation coefficients * All calculations must use formulas or proper tools (not manual typing) 5. Statistical Analysis * Correlation significance testing (α = 0.05) * Normality testing (to determine correct tests) * One-sample test: mean number of apps > 3 * Comparison of weekly usage across specializations: * Use appropriate test (ANOVA or alternative) * Check normality and variance assumptions 6. Regression Model * Build a model to predict GPA * Select appropriate independent variables * Interpret results clearly 7. Interpretation (VERY IMPORTANT) * Provide clear comments on: * Descriptive results * Scatter plots * Correlations * Hypothesis tests * Regression model ⸻ Deliverables: * Word report (proper academic format) * Excel file (clean + formulas + charts) * Minitab file (all statistical tests) ⸻ Requirements: * Work must be accurate and ready for university submission * Must follow proper statistical methodology (no shortcuts) * Charts must be clear and correctly labeled * Freelancer must have strong experience in statistics, Excel, and Minitab

Hi, I am an MBA with strong experience in statistics, Excel, and academic report writing. I can prepare the full statistical analysis project with sample size, dataset, formulas, charts, correlations, hypothesis tests, ANOVA OR alternative tests, and regression. I will create a clean Excel workbook with raw data, descriptive statistics, labeled scatter plots, and proper formulas tools. I will also write a university-ready Word report with clear interpretation of all results and methodology. I can structure the Minitab analysis requirements clearly and ensure the final work is accurate, professional, and submission-ready.

Hi, Sample-size calc and variable distributions suggest the sample formula with σ=0.51 at 95% and MOE=0.1 will require ~97–100 students; I’ll confirm exact n and stratify by your provided specialization percentages (23/30/22/25). You want Excel + Minitab + Word-ready reporting with formal tests and reproducible formulas. First diagnostic/action: - compute required n and generate stratified random draw plan - perform normality (Shapiro/K-S), Levene’s for variance, correlation tests, ANOVA or Kruskal–Wallis, and build multiple regression with diagnostics (VIF, residuals) I will flag risks to validity (sampling bias, non-normality, missing data) and fix them before reporting. Ready to start—shall I proceed with sample calculation and template files? — Smith

Engineering Statistics Project – Full Analysis requires precise execution across sample design, descriptive analysis, hypothesis testing, and predictive modeling. The challenge lies in ensuring methodological rigor across Excel formulas, Minitab validation, and clear statistical interpretation without computational shortcuts. This project aligns directly with core competencies: statistical analysis using SPSS and R, Excel modeling with formulas, descriptive statistics, correlation analysis, normality testing, ANOVA/hypothesis testing, and regression modeling. The deliverable structure—raw data sheet, descriptive breakdowns by specialization, scatter plots with Pearson coefficients, and assumption checking—matches standard statistical workflow. Deliverables will include a properly formatted Word report with academic-level interpretation, clean Excel file with all formulas visible and charts correctly labeled, and Minitab output documenting normality tests, significance testing at α=0.05, and regression diagnostics. Sample size calculation will use standard formulas; stratified sampling will reflect the four specialization percentages. The regression model will be built through variable selection and justified through R² and coefficient interpretation. Every statistical decision—test selection, assumption validation, result interpretation—will follow proper methodology suitable for university submission.

Hi there, I can handle your full statistical analysis project from start to finish with proper academic standards. I’ll calculate the sample size, create a well-structured dataset, and organize it clearly in Excel with formulas (not manual entries). The file will include descriptive statistics (overall and by specialization), scatter plots, and Pearson correlations. I will also perform all required statistical tests such as normality checks, correlation significance, one-sample test, and ANOVA (or suitable alternative), making sure assumptions are properly verified. Along with that, I’ll build a reliable regression model to predict GPA and explain the results in simple, clear language. You’ll receive a clean Excel file, a properly formatted Word report with interpretations of every result, and a Minitab file showing all tests. The work will be accurate, well-presented, and ready for direct university submission.
