Nội dung khóa học
Unit 1: Exploring One-Variable Data
You’ll be introduced to how statisticians approach variation and practice representing data, describing distributions of data, and drawing conclusions based on a theoretical distribution.
Unit 2: Exploring Two-Variable Data
You’ll build on what you’ve learned by representing two-variable data, comparing distributions, describing relationships between variables, and using models to make predictions.
Unit 3: Collecting Data
You’ll be introduced to study design, including the importance of randomization. You’ll understand how to interpret the results of well-designed studies to draw appropriate conclusions and generalizations.
Unit 4: Probability, Random Variables, and Probability Distributions
You’ll learn the fundamentals of probability and be introduced to the probability distributions that are the basis for statistical inference.
Unit 5: Sampling Distributions
As you build understanding of sampling distributions, you’ll lay the foundation for estimating characteristics of a population and quantifying confidence.
Unit 6: Inference for Categorical Data: Proportions
You’ll learn inference procedures for proportions of a categorical variable, building a foundation of understanding of statistical inference, a concept you’ll continue to explore throughout the course.
Unit 7: Inference for Quantitative Data: Means
Building on lessons learned about inference in Unit 6, you’ll learn to analyze quantitative data to make inferences about population means.
Unit 8: Inference for Categorical Data: Chi-Square
You’ll learn about chi-square tests, which can be used when there are two or more categorical variables.
Unit 9: Inference for Quantitative Data: Slopes
You’ll understand that the slope of a regression model is not necessarily the true slope but is based on a single sample from a sampling distribution, and you’ll learn how to construct confidence intervals and perform significance tests for this slope.
