Course Description

Statistics Fundamentals: From Data to Decisions is a practical ebook course in basic studies that helps you build statistical thinking for everyday and professional decision making. If you work with reports, dashboards, experiments, or surveys, this course shows how to turn raw data into clear conclusions while avoiding common mistakes.

You will learn to recognize data types and measurement scales, organize a dataset, and describe categorical data using counts, proportions, and rates in a way that supports accurate comparisons. You will also summarize quantitative data with measures of center and spread, then interpret distributions by focusing on shape, skew, and outliers so your insights reflect what the data is truly saying.

As you progress, you will examine relationships between variables, including correlation, association, and confounding, so you can distinguish meaningful patterns from misleading ones. The course connects samples to populations through sampling concepts, bias, and variability, giving you the foundation needed to judge whether evidence is representative and reliable in real world settings.

To interpret uncertainty with confidence, you will study probability basics, random variables, and common distribution patterns. You will then apply estimation through confidence intervals as ranges of plausible values and use hypothesis testing to evaluate evidence without overstating results. Throughout the course, you will practice reading statistical results and translating them into responsible, data driven decisions that stakeholders can trust.
