DATA 320: Introduction to Data Analytics

Introduction to Data Analytics builds foundational statistical analysis skills — summary statistics, visualization, statistical inference, and predictive analytics.

What DATA 320 covers

(Formerly DATA 220.) Prerequisite: STAT 200. A practical introduction to the methodology, practices, and requirements of data science to ensure that data is relevant and properly manipulated to solve problems and address a variety of real-world projects and business scenarios.

Focus is on the application of foundational statistical concepts to describing data sets with summary statistics, simple data visualizations, statistical inference, and predictive analytics. The objective is to use data to draw conclusions about the underlying patterns that drive everyday problems through probability, hypothesis testing, and linear model building.

Typical DATA 320 assignments

Expect an assignment requiring you to apply statistical inference or hypothesis testing to a real-world dataset to draw a conclusion about an underlying pattern.

Key topics in DATA 320

• Summary statistics and simple visualizations
• Statistical inference
• Hypothesis testing
• Linear model building

Writing tips for DATA 320

Follow the assignment instructions and rubric line by line

UMGC assignments for DATA 320 are graded against a specific rubric or grading criteria your instructor provides — every requirement has to be visibly addressed. Skipping a requirement because it seems minor is one of the most common reasons a strong submission loses points.

Show your data work, not just the final numbers

Data Analytics courses like DATA 320 usually grade the actual analytical process — data cleaning, the code or queries used, and the reasoning behind method choices — not just a polished chart or summary statistic at the end.

Ground your work in a specific scenario, dataset, or organization

Strong submissions in this discipline are grounded in a specific, named scenario — a particular organization's policy gap, or a particular dataset's patterns — rather than discussing concepts generically. Evaluators check whether your conclusions are actually supported by the specific case given.

Why students seek help with DATA 320

Students sometimes report summary statistics without the statistical inference or hypothesis testing the course specifically requires to draw a genuine conclusion — the rubric typically wants that inferential step shown, not summary statistics alone.

How GradeEssays helps with DATA 320

Share your dataset and assignment prompt, and your writer will build an analysis using statistical inference or hypothesis testing to reach a genuine, supported conclusion.

Prerequisites and course context

DATA 320 requires STAT 200. It was formerly numbered DATA 220, and is itself the required prerequisite for DATA 335 (Data Visualization). Note: DATA 320 is also a prerequisite for OPMG 495 in the Business/Management discipline (shipped in um5).
