**Project Title: Statistical Analysis of Real-World Data** **Objective:** The objective of this project is to apply statistical concepts and methods learned in the statistics class to real-world datasets. By engaging in data analysis and interpretation, students will develop practical skills in statistical reasoning and hypothesis testing. **Instructions:** 1. **Selecting a Dataset:** - Choose a dataset from a reputable source that aligns with your interests or area of study. Datasets can be obtained from sources such as government databases, research organizations, or data repositories. - Ensure that the dataset contains variables suitable for statistical analysis, including numerical and categorical variables. 2. **Formulating Research Questions:** - Develop 3-5 research questions that can be explored using the selected dataset. Your research questions should be clear, specific, and relevant to the variables in the dataset. - Consider both descriptive and inferential questions that can be addressed through statistical analysis. 3. **Data Cleaning and Preparation:** - Clean and prepare the dataset for analysis by addressing missing values, outliers, and inconsistencies. - Perform data transformations or recoding as necessary to make the data suitable for analysis. - Document the steps taken in data cleaning and preparation. 4. **Descriptive Statistics:** - Calculate descriptive statistics (e.g., mean, median, standard deviation, frequency distributions) for relevant variables in the dataset. - Create visualizations (e.g., histograms, box plots, bar charts) to summarize and present the distribution of data. 5. **Inferential Statistics:** - Choose appropriate inferential statistical tests based on the nature of your research questions and the types of variables in the dataset. - Conduct hypothesis tests (e.g., t-tests, chi-square tests, ANOVA) to test hypotheses and draw conclusions based on the results. - Interpret the findings in the context of your research questions and provide explanations for the observed patterns. 6. **Report and Presentation:**

- Write a research report summarizing your findings, methodology, and conclusions. Include relevant tables, figures, and statistical output. - Prepare a brief presentation to communicate your findings to the class. Highlight key findings, insights, and implications of your analysis. **Submission Guidelines:** - Submit your research report and presentation slides electronically through the course's online platform. - Include any additional materials such as code files, data dictionaries, or syntax used for data analysis. **Grading Criteria:** - Clarity and coherence of research questions - Accuracy and completeness of data cleaning and preparation - Appropriateness and rigor of statistical analysis - Interpretation and discussion of findings - Quality of written report and presentation delivery
