Statistics Fundamentals for Data Science

What you'll learn

⚡ Understand how statistics uses a sample to draw and defend conclusions about an entire population, with intuition first and no heavy math required.
⚡ Read and interpret the key distributions in data science: the normal and CLT, plus the t, chi-square, and F-distributions, and how they connect.
⚡ Choose the right statistical test for any problem and know why it fits, from one-sample and two-sample t-tests to ANOVA and chi-square.
⚡ Run a hypothesis test end to end: set up the hypotheses, compute the statistic, read the p-value, check assumptions, and reach a sound decision.

Requirements

❗ No prior statistics knowledge is needed. The course starts from the very basics and builds every idea from the ground up.
❗ Comfort with basic arithmetic and simple high-school algebra is enough. If you can work with fractions, averages, and square roots, you are ready.
❗ No programming experience required. The focus is on understanding the concepts, not on coding.
❗ No paid software or special equipment needed. A calculator and a willingness to think through examples are all you need.
❗ Most of all, bring curiosity. If you have ever wondered what the numbers behind data science actually mean, this course is for you.

Description

This course contains the use of artificial intelligence.
A practical, beginner-friendly path through statistics for data science—from describing the data in front of you to making inferences you can actually defend.
Statistics is the backbone of data science, but it's often taught as a wall of formulas that's easy to memorize and hard to truly understand. This course takes the opposite approach. Across eight focused modules, we build your intuition first, so that every concept clicks before we ever worry about the math. No heavy background is required — if you're comfortable with basic ideas, you're ready to start.
The course moves in one clear direction. We begin with the foundations: how to describe and prepare data, and the core vocabulary everything else is built on. From there, we explore the handful of distributions—the normal distribution and the Central Limit Theorem, the t-distribution, and the chi-square and F-distributions—that model almost everything you'll encounter, and we see how they connect. Finally, we reach inference: turning a limited sample into a defensible claim about an entire population, through hypothesis testing and the statistical tests used in real practice.
One thread runs through it all: a sample is only a glimpse of a population, and statistics is the discipline of saying how much that glimpse can be trusted. By the end, you won't just run the tests—you'll understand what they mean and why they work.

Who this course is for

⭐ Beginners who want to understand statistics from scratch, without a heavy math background.
⭐ Aspiring data scientists and analysts who want a solid statistical foundation before moving into machine learning.
⭐ Students taking a statistics course who want clear, intuitive explanations to complement their studies.
⭐ Professionals working with data who want to understand what the numbers and tests actually mean, not just how to run them.
⭐ Anyone curious about how data science draws reliable conclusions from limited data.
