About statistical inference notes

GoConqr Original

Using statistical inference notes

These notes cover several approaches to inference. Inferential Statistics introduces populations and sampling error, while Statistics Chapter 6 looks at using sample statistics to estimate a population parameter. Module 5 Notes discusses the normal approximation to the binomial.

For a starting point, try Inferential Statistics if you want to revisit the language of populations and samples. If estimation is your focus, start with Statistics Chapter 6 instead.

Make notes work for revision

Read a section, then put its main idea into your own words before checking the original. For a different topic, Week 8: cross tabulation compares variables and introduces null and alternative hypotheses. Advanced Statistics covers research design and errors.

When you want to check your recall rather than read further, switch to a quiz on the unit page. You can also use a mind map to revisit how ideas connect. Choose a topic and start reading.

Frequently asked questions

Which note should I start with?

Inferential Statistics is a useful starting point for revisiting populations and sampling error. If you are working on estimation, Statistics Chapter 6 covers using sample statistics to estimate an unknown population parameter. Module 5 Notes is another option if you are studying the normal approximation to the binomial.

Are these notes free to use?

Yes. Every note listed here is free to open and study, without an account. The resources were made by GoConqr users. A free account can save quiz scores and lets you make your own quizzes, mind maps, flashcards and notes.

Who are these notes for?

The collection is mostly at university level. University students and professional candidates can use the notes to practise topics such as sampling and hypothesis testing. Teachers can also look for material to share. Unit 5 Overview mentions AP Statistics among its reading references.
