Introduction to Statistics

What the resources cover

This unit page collects early-course statistics material made by GoConqr users. Much of it follows a typical first chapter: what statistics is, what data and a data set are, and how variables and observations are described. Several flashcard decks, such as Chapter One, ask you to define terms like nominal scale and ordinal scale. The deck Unit 1 asks what the subjects in a data table are called and whether variables sit in rows or columns.

Where to start

Begin with a broad mind map to see the whole topic on one screen. Several maps are simply called Statistics, and Descriptive and Inferential Statistics splits the subject into its two main branches. The Edexcel S1 Topic Map is a useful overview too, linking graphs and charts, summary statistics, probability, correlation and regression. Mentions of A-level Mathematics on the page suit school students who want a revision outline.

Then test yourself

Once the vocabulary looks familiar, move to the quizzes. Psychological Statistics asks you to classify a group of 25 five year olds in a research study. Stats Midterm uses a student estimating the proportion of students who own a red car, which makes you think about samples and populations. Final Study Guide. asks about a statistic calculated on a population and about matching statements to sample or population.

Using quizzes and maps together

1. Read a map and say each branch aloud without looking.
2. Take a quiz on the same ideas.
3. Note the questions you missed and find the matching flashcards.
4. Return to the map and fill in what was missing.

The flashcard deck Chapter 1 Statistics Vocab works well for the last step, and the map Interpretation of Statistics goes further, covering ideas such as power as the probability of a significant result.

Where it fits

This unit sits in the Foundations of Statistics strand of Statistics and probability. It is the place to settle the basic language before moving on to more advanced work. Open a resource that matches your course, and add your own maps or flashcards when you spot a gap.
