What is categorical data? Great question! That’s exactly what we’re going to cover in today’s statistic lesson. You’re going to learn the differences between categorical and quantitative data, how to represent the data, and so much more. Let’s get started! The purpose of statistics is more than just collecting and organizing data. It is about…
Probability
Probability is the measure of how likely it is for an event to occur, and conditional probability is the likelihood of an event occurring, given another event has already occurred. But to fully understand what all of this means, it’s important to learn the terminology and the notation involved in calculating probability. We will begin…
Empirical Rule
Wouldn’t it be nice to be able to find the likelihood of an event occurring without having to do too much work? This is the beauty behind normal distribution and the empirical rule! For a given data set with symmetric distribution, that looks like a bell curve, approximately 68% of the observations fall within just…

All of the topics are covered in detail in our Online Algebra Course. The online course provides the following: Full Lectures – Designed to boost your test scores.…
Percents
Ratios and proportions help us in solving problems with percents. Why? Because a percent is the ratio (fraction) of one number to another. In other words, its a number divided by 100. What is most important to note is that our overall goal is to translate each problem into an algebraic expression by looking for…

Inverse Trig Functions
Have you ever put on an article of clothing, only to find out that it wasn’t the right size? Well, guess what, this same dilemma can be seen in mathematics…. albeit, not with clothing but with Inverse Trigonometric Functions! Remember how the domain of our basic Trigonometric Functions (i.e., Sine and Cosine) are all real…
Solving Trig Equations Using Inverses
In this video lesson we will discover how to Solve Trigonometric Equations using Inverses. In our previous lesson, we learned all the tricks and techniques for solving all types of trigonometric equations using the Unit Circle. Well, in this lesson, we are going to combine these same skills, but also use the power of Inverses…
