Each course contains all of the instructions for the four statistics packages options we support. One of the main differences between the courses is the path through probability. Probability and Statistics includes the classical treatment of probability as it is in the earlier versions of the OLI Statistics course. There are two versions of the OLI Statistics course: Both versions have four units with the difference between the two versions being in the third unit Probability as outlined below.

The course is built around a series of carefully devised learning objectives that are independently assessed. Most of the interactive tutors are tagged by learning objective and skill, and so student work can be tracked by the system and reported to the instructor via the Learning Dashboard. These give the instructor insight into mastery of learning objectives and skills, both for the class as a whole and for individual students.

The course was designed to be used as a stand alone with no instruction in the background however studies have shown that it is best and most effectively used in the hybrid mode together with face to face instruction.

Additional Course Details Topics Covered: When is it appropriate to use this technique? The answers to these and other related questions await you in the following lesson. In this lesson, we explore what is sample space, how it is related to probability and the formula to use to find it when given probability problems.

This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of basic probability and statistics. Have fallen behind in understanding probability or how to working with statistics. Need an efficient way to learn about basic probability and statistics. Learn best with engaging auditory and visual tools. Struggle with learning disabilities or learning differences, including autism and ADHD.

Experience difficulty understanding your teachers. Missed class time and need to catch up. How do I interpret bar graphs and pie charts? How can I use tables to compute percent increases? What steps do I follow to find medians, means, modes and ranges? How do I find the standard deviation of a data set? How do I calculate the probability of events? What steps do I follow when calculating permutations?

Basic Probability and Statistics: Test your knowledge with a question chapter practice test. View all practice tests in this course. Understanding Bar Graphs and Pie Charts In this lesson, we will examine two of the most widely used types of graphs: Calculating the Standard Deviation In this lesson, we will examine the meaning and process of calculating the standard deviation of a data set.

Probability of Simple, Compound and Complementary Events Simple, compound, and complementary events are different types of probabilities. Probability of Independent and Dependent Events Sometimes probabilities need to be calculated when more than one event occurs. Overlapping and Non-Overlapping Events Statistics is the study and interpretation of a set of data.

Probability of Independent Events: How to Calculate Simple Conditional Probabilities Conditional probability, just like it sounds, is a probability that happens on the condition of a previous event occurring.

Formula and Example Problems Combinations are an arrangement of objects where order does not matter. How to Calculate the Probability of Combinations To calculate the probability of a combination, you will need to consider the number of favorable outcomes over the number of total outcomes.

How to Calculate a Permutation A permutation is a method used to calculate the total outcomes of a situation where order is important. How to Calculate the Probability of Permutations In this lesson, you will learn how to calculate the probability of a permutation by analyzing a real-world example in which the order of the events does matter.

Tree Diagrams in Math: What is Range in Math? Formula of Sample Space in Math In this lesson, we explore what is sample space, how it is related to probability and the formula to use to find it when given probability problems.

Together, these outcomes represent the sample space of our experiment. Individually, each outcome represents a sample point in the sample space. What is the probability of each sample point? The sum of probabilities of all the sample points must equal 1. And the probability of getting a head is equal to the probability of getting a tail.

If we toss a fair die, what is the probability of each sample point? For this experiment, the sample space consists of six sample points: Each sample point has equal probability.
