Introduction to Statistics
By Coast Learning Systems - 2011
We are bombarded with statistics every day. But what do all these numbers mean and who really uses them? This lesson introduces you to the many uses…
Displaying Data
By Coast Learning Systems - 2011
This lesson begins by explaining statistics and how it is used by scientists. You will learn that statistics is not a meaningless compilation of…
Describing Distributions
By Coast Learning Systems - 2011
Professionals of all types must make sense out of the huge amounts of data they collect on a daily basis. Researchers first try to impose some sort…
Normal Distributions
By Coast Learning Systems - 2011
As you have seen in earlier lessons, statisticians have visual and numerical ways of describing a set of data. Histograms are one of the most common…
Scatterplots & Correlation
By Coast Learning Systems - 2011
Questions about the relationship between two variables are asked all the time. Will time spent in a certain rehab program really increase an addict's…
Regression
By Coast Learning Systems - 2011
We have all had the experience watching our friends and family play sports or games. Based on prior performance, we predict in our heads how they…
Two- Way Tables
By Coast Learning Systems - 2011
Researchers are often interested in variables that are categorical in nature. These often involve people who fall into certain groups, such as age…
Producing Data: Sampling
By Coast Learning Systems - 2011
Polls are something we encounter everyday in the media. We are constantly bombarded with numbers of how many people approve of the President's…
Producing Data: Experimentation
By Coast Learning Systems - 2011
Every day, the media bombard us with the results of recent statistical studies. Statements like, "Studies show our products are better than ever…
More on Experimentation
By Coast Learning Systems - 2011
Experimental studies are powerful tools that researchers use to determine cause and effect relationships. These studies are picked up in the media…
Introduction to Inference
By Coast Learning Systems - 2011
Inferences are something we make every day. Every time we draw a conclusion based on evidence, we are making an inference. For example, if we meet…
Probability
By Coast Learning Systems - 2011
What are the chances?" We think this many times a day. Why is it raining when the weatherman said there was only a five percent chance of rain? Why…
Sampling Distributions & the Central Limit Theorem
By Coast Learning Systems - 2011
In previous lessons, you learned about the proper techniques researchers use when sampling a population, and how they infer meaning out of sample…
Confidence Intervals
By Coast Learning Systems - 2011
Confidence intervals are something we see in the news almost daily, most frequently as polling results. They are the most commonly reported…
Tests of Significance
By Coast Learning Systems - 2011
Testing ideas lies at the heart of statistics. Researchers must have unifying criteria to determine whether the results they see are evidence of real…
Cautions About Inference
By Coast Learning Systems - 2011
Statistics is a powerful tool for discovering how the world works, but we must be cautious when interpreting what the numbers mean when we calculate…
Inference for One Mean
By Coast Learning Systems - 2011
This lesson pursues a more realistic test of significance than the z test discussed in Lesson 15. In that lesson, you learned to use the z test to…
Comparing Two Means
By Coast Learning Systems - 2011
In this lesson we learn about a second and important t procedure, the two-sample t test. This test is one of the most widely used statistical tests…
Inference for One Proportion
By Coast Learning Systems - 2011
This lesson returns to the topic of proportions, applying what you have learned about confidence intervals, margins of error, and tests of…
Comparing Two Proportions
By Coast Learning Systems - 2011
This lesson extends what you learned in Lesson 19 about single-sample proportions to the concept of two-sample proportions. Researchers use…
Choosing Inference Procedures
By Coast Learning Systems - 2011
This lesson is a review of what you have learned so far in the course. You have learned about proper study design, the types of variables under…
Chi-Square Tests
By Coast Learning Systems - 2011
This lesson goes a step farther in what can be done with categorical data. Researchers often look at questions that have more than two categorical…
Inference for Regression
By Coast Learning Systems - 2011
This lesson returns to the topic of regression introduced in Lessons 5 and 6. While researchers benefit from knowing the correlation between two…
Multiple Regression: Building the Model
By Coast Learning Systems - 2011
This lesson expands on the last lesson on regression to consider cases in which there is more than one predictor variable. Statisticians often do…
Multiple Regression: Refining the Model
By Coast Learning Systems - 2011
This lesson further examines multiple regression by closely examining the predictor variables involved in the regression model. Researchers often…
Logistic Regression
By Coast Learning Systems - 2011
This lesson deals with a special type of regression in which the response variable is categorical and the explanatory variable is a quantitative…
One-Way ANOVA
By Coast Learning Systems - 2011
This lesson introduces another type of statistical test that evaluates the means of numerical data. In previous lessons, we used the two-sample t…
