The Probability and Statistics Cheat Sheet provided by Mathcentre is a reference guide that helps students understand and apply key concepts in probability and statistics. It includes formulas, definitions, and strategies for solving problems in these areas of mathematics.

Q: What is probability?

A: Probability is the measure of how likely an event is to occur.

Q: What is statistics?

A: Statistics is the study of data collection, analysis, interpretation, presentation, and organization.

Q: What is a random variable?

A: A random variable is a variable that takes on different values based on the outcome of a random event.

Q: What is the difference between discrete and continuous random variables?

A: Discrete random variables can only take on specific values, while continuous random variables can take on any value within a range.

Q: What is the mean?

A: The mean is the average of a set of numbers.

Q: What is the median?

A: The median is the middle value in a set of numbers when they are arranged in order.

Q: What is the mode?

A: The mode is the value that appears most frequently in a set of numbers.

Q: What is the standard deviation?

A: The standard deviation measures the amount of variability or dispersion in a set of numbers.

Q: What is a confidence interval?

A: A confidence interval is an estimate of the range of values within which a population parameter is likely to fall.

Q: What is hypothesis testing?

A: Hypothesis testing is a statistical method used to make inferences about a population based on sample data.
