Foundations of Data and Statistics: Understanding, Collecting, and Presenting Information

This course offers a solid foundation in how we gather, interpret, and use information in everyday life. We begin by recognizing that information surrounds us constantly—whether in the form of facts, figures, tables, or graphs—and explore what “data” truly means. You will be introduced to statistics as the branch of mathematics dedicated to making sense of data, and discover the various meanings behind the term “statistics” itself.

To deepen your understanding, you’ll be invited to identify and collect five examples of data from your own daily experiences.

Next, we will differentiate between primary data—collected firsthand through surveys, experiments, and observations—and secondary data—gathered from existing sources like government reports, research journals, and online databases. You’ll learn the advantages and disadvantages of each type and why understanding these differences is vital in any data-related work.

Once data is collected, organizing and presenting it becomes essential. The course explains the importance of data presentation and why simply listing data in order isn’t always effective. You will learn how to create ungrouped frequency distribution tables to neatly organize raw data, and progress to grouped frequency distribution tables, with clear examples to guide you. Through practical exercises, such as adjusting grouped tables to include new data points, you’ll develop hands-on skills in data handling.

Finally, we highlight the broad relevance of statistics across fields like business, healthcare, social sciences, and engineering. By understanding data and statistical methods, you’ll be better equipped to make informed decisions in both professional and personal contexts.

This course will empower you to confidently navigate our data-rich world with fundamental skills in data collection, analysis, and presentation.
