Summary
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, and presentation of data. It is used in business to make informed decisions based on data. This document covers many topics in statistics, with questions on each.
Regression models
Regression models are used to understand relationships between variables. It explains the difference between models like y = A + Bx + e and y = A + Bx.
Hypothesis testing
Hypothesis testing is a formal process to make decisions based on data. It describes the null and alternative hypotheses and how to test them. It asks about the p-value and critical values in hypothesis tests.
Types of variables
Variables are characteristics that can take on different values. It explains the difference between quantitative and qualitative variables. It describes what a discrete random variable is.
Probability and distributions
Probability is the measure of the likelihood that an event will occur. It explains the mean of a discrete random variable. It asks about the chi-square distribution and the sampling distribution of the sample mean.

- Quantitative variable
- A variable that can take on any numerical value.
- Qualitative variable
- A variable that describes qualities or categories.
- p-value
- The probability of obtaining test results at least as extreme as the results actually observed.
- Analysis of variance
