Data Science Starter Kit Module 3: Making Sense of Data - Analysis and Modeling

Welcome to the exciting part of data science—making sense of the information you’ve collected! This module focuses on how to analyze data to find patterns, understand what the numbers really mean, and start drawing conclusions.🔗

Analysis and Modeling isn’t about complex mathematics or advanced statistics. It’s about developing the thinking skills to look at data and ask, “What story is this telling me? What patterns do I notice? What questions does this raise?” Whether students are working with simple tally marks or sophisticated datasets, the fundamental thinking is the same.

3–5 Competencies

Calculate the range for numerical data.

Is Simone Biles the GOAT? by DataClassroom

The purpose of this lesson is to help students apply advanced statistical concepts including data standardization, correlation analysis, and comparative modeling to evaluate claims about athletic performance across different time periods. Students will learn to use z-scores and statistical inference to make fair comparisons when raw data cannot be directly compared due to changing conditions and scoring systems.

How Many Babies to Make the Average? by DataClassroom

The purpose of this lesson is to help students understand fundamental concepts of statistical sampling theory and the Central Limit Theorem through hands-on simulation of birth weight data. Students will explore how sample size affects the reliability of population parameter estimates, discover the theoretical foundations of statistical inference, and develop intuition about the practical considerations of sampling in real-world research.
