Data Project: ……………. Data Analysis Project The project involves the following five parts: · Introduction (what is the hypothesis you want to test; what is the population data you have in mind) · Data collection (what your sample data is and from where you collect them; on what basis you are convinced the sample is random) · Data summary and visualization (the basic summary statistics of your data and a visualization of the main feature of the data) · hypothesis testing (a statistical statement of the hypothesis you want to test and the test statistics that you have computed) · conclusion (what you can conclude concerning your hypothesis based on your test statistics) You can choose your favorite statistical software to conduct the project.

Each student is asked to write a two-page memo of the data project detailing the above four parts and to submit the data file along with the memo. To assist you with managing the schedule working on your data project, I create four milestone checkpoints on canvas before the final submission for you to self-check whether you are on track or not. You can submit the related material at that point to show me that you have attained the milestones, but these submissions will not be graded and will not be credited. The only way to earn more credits is to make your final submission before the final week (more details in the grading section). Data Project for Eco3410 Professor Dr.Sheng Guo

The Data Analysis Project for Eco3410 involves a comprehensive investigation of a specific hypothesis using statistical methods. The project is divided into five main parts: introduction, data collection, data summary and visualization, hypothesis testing, and conclusion. Each of these components aims to build a coherent narrative from formulating an initial hypothesis to drawing substantive conclusions based on data analysis.

The first step, the introduction, requires students to state clearly the hypothesis they intend to test, along with specifying the population data relevant to this hypothesis. For example, a student might explore whether there is a statistically significant difference in average household income between different regions or demographic groups. Defining the population data set is crucial because it frames the scope of the analysis and determines the applicability of the results.

Data collection involves identifying a sample of data and the source from which it is obtained. Ensuring the randomness of the sample is critical for statistical validity; thus, students must justify their sampling method. For instance, data could be collected through random surveys or from a publicly available random sampling of records, underpinning assumptions about sample validity and representativeness.

The data summary and visualization section entails computing basic descriptive statistics—such as mean, median, variance, and range—and creating visual representations like histograms, box plots, or scatter plots. These visual tools help reveal key features of the data, such as skewness, outliers, or correlations, providing insight into the structure and distribution of the dataset.

Following this, hypothesis testing involves formulating a null hypothesis and an alternative hypothesis, then selecting an appropriate test statistic (such as t-test, chi-square, or ANOVA) based on the data and the research question. Calculating the test statistic and corresponding p-value allows the researcher to evaluate whether there is sufficient evidence to reject the null hypothesis in favor of the alternative.

The final component, the conclusion, synthesizes the results of the hypothesis test. It should explicitly state whether the data provides enough evidence to support or reject the initial hypothesis, considering the significance level used. This section also discusses implications, limitations, and potential directions for further research.

The structure of the data project emphasizes clarity, transparency, and rigorous statistical analysis. Students are encouraged to use any statistical software they are comfortable with, such as R, Stata, SPSS, or Python, to carry out the analysis efficiently and accurately. The final deliverable is a two-page memo that succinctly summarizes each component, supplemented by the data file used for analysis.

This project aims to develop practical skills in data collection, descriptive statistics, data visualization, hypothesis testing, and interpretation—fundamental tools for empirical research in economics and social sciences. The milestone checkpoints serve as a guide to ensure steady progress, although they are ungraded; the focus remains on the timely and quality final submission.
