This lesson defines the term random variables in the context of probability. You'll learn about certain properties of random variables and the different types of random variables.

Graphing Probability Distributions Associated with Random Variables

2. Graphing Probability Distributions Associated with Random Variables

What's a random variable? Does it have anything to do with gambling? What's the difference between a continuous and a discrete variable? This lesson explains the difference and how to graph each one.

Sampling Distribution: Definition, Models & Example

3. Sampling Distribution: Definition, Models & Example

Researchers frequently use sample data to draw conclusions about a population using sampling distributions. In this lesson, you will learn about the definition of a sampling distribution and review an example with an illustration.

Sample Proportion in Statistics: Definition & Formula

4. Sample Proportion in Statistics: Definition & Formula

This lesson talks about the definition, formula, and use of the sample proportion. We also see a brief intro into the concept of margin of error and selection of sample size. After completing the lesson, take a short quiz to see what you have learned.

Calculating Confidence Intervals, Levels & Coefficients

5. Calculating Confidence Intervals, Levels & Coefficients

In this lesson, you're going to learn about confidence intervals, confidence levels, and coefficients, and how they relate to point estimates and interval estimates.
