The course objective is to equip you with the tools to apply statistical principles to answer questions and solve problems. You will also learn about various topics in statistics, including probability, sampling distributions and hypothesis testing.
Grading Policy
Your grade for this course will be calculated out of 300 points. The minimum score required to pass and earn real college credit for this course is 210 points, or an overall course grade of 70%. The table below shows the assignments you must complete and how they'll be incorporated into the overall grade.

Quizzes
Quizzes are meant to test your comprehension of each lesson as you progress through the course. Here's a breakdown of how you will be graded on quizzes and how they'll factor into your final score:
 You will have 3 attempts to take each quiz for a score.
 The highest score of your first 3 attempts will be recorded as your score for each quiz.
 When you've completed the course, the highest scores from your first 3 attempts at each quiz will be averaged together and weighed against the total possible points for quizzes. For instance, if your average quiz score is 85%, you'll receive 85 out of 100 possible points for quizzes.
 After your initial 3 attempts, you can take a quiz for practice as many times as you'd like.
 You will need to pass each quiz with a score of at least 80% to earn course progress for the lesson. However, it is not necessary to earn 80% within the first three quiz attempts.
Proctored Final Exam
The proctored final exam is a cumulative test designed to ensure that you've mastered the material in the course.
 You'll earn points equivalent to the percentage grade you receive on your proctored final. (So if you earn 90% on the final, that's 180 points toward your final grade.)
 If you're unsatisfied with your score on the exam, you'll be eligible to retake the exam after a 3day waiting period.
 You can only retake the exam twice, so be sure to use your study guide and fully prepare yourself before you take the exam again.

Prerequisites
There are no prerequisites for this course, but many students choose to complete Statistics 101: College Algebra prior to Principles of Statistics.
Course Format
Statistics 101 consists of short video lessons that are organized into topical chapters. Each video is approximately 510 minutes in length and comes with a quick quiz to help you measure your learning. The course is completely selfpaced.

Additional Information
Course Topics
Overview of Statistics  Learn to identify the differences between inferential and descriptive statistics and populations and parameters. Explore various data types and levels of measurement alongside methods for selecting experiment models. Get tips for recognizing biased or misleading uses of statistics. 
Summarizing Data  Find out how to calculate the center, mean, median, and mode, and describe the shape of a data set. Study procedures for finding maximums, minimums, outliers and percentiles within data sets. Identify standard deviations and methods for ordering and ranking data. 
Tables and Plots  Explain both relative and cumulative frequency. Interpret stem and leaf displays, histograms and frequency polygons as well as dot and box plots, bar graphs, pie charts and twoway tables. Use data to make predictions and calculate percent increase. Discover joint, marginal and conditional frequencies and identify the differences between bivariate and univariate data. 
Probability  Define unions, intersections and elements as well as events as subsets. Understand basic set theory and classical approaches to probability. Learn how to find the probability of simple, compound and complementary events as well as independent and dependent events. Show connections between independent and conditional probabilities. Observe how simple conditional probabilities can be applied to realworld scenarios. Learn the addition and multiplication rules, practice applying math combination formulas, and work on calculating permutations and the probability of permutations. Look back at classical approaches to probability and relative frequency. 
Discrete Probability Distributions  Define random variables. Practice graphing and interpreting discrete probability distributions used to find expected values in games of chance. Examine discrete probability concepts, binomial probabilities and formulas, standard deviation and mean of a binomial random variable, and problemsolving steps for binomial experiments. 
Continuous Probability Distributions  Learn to graph continuous probability distributions and find their expected values. Explore the uses of these distributions to estimate area and population percentages, and go over related theories and terminology. 
Sampling  Explore simple, stratified, cluster, and systematic random samples. Study the law of large numbers and discuss the central limit theorem, sampling distributions and sample means. 
Regression & Correlation  Learn how to create and interpret scatterplots, solve problems using linear regression and analyze residuals. Practice finding the correlation coefficient and the coefficient of determination. Distinguish between correlation and causation and find out how to transform nonlinear data. 
Statistical Estimation  Identify the relationships between confidence intervals, sample size and sample means. Examine properties of the tdistribution and learn about biased and unbiased estimators as well as point and interval estimation. Explore confidence intervals for matched pairs, independent samples, proportions, and independent samples with equal variances. 
Hypothesis Testing  Follow steps in hypothesis testing for small and large independent samples, matched pairs and proportions. Understand the differences between type I and type II errors. Explore the relationship between hypothesis tests and confidence intervals.
