Chapter 9 Chapter 9 Experimental Research (Reminder: Don’t forget to utilize the concept maps and study questions as you study this and the other chapters.) In this chapter we talk about what experiments are, we talk about how to control for extraneous variables, and we talk about two sets of experimental designs (weak designs and strong designs). (Note: In the next chapter we will talk about middle of the road experimental designs; they are better than the weak designs discussed in this chapter, and they are not as good as the strong designs discussed in this chapter. The middle of the road, or medium quality designs are called quasi-experimental designs.) It is important for you to remember that whenever an experimental research study is conducted the researcher's interest is always in determining cause and effect. The causal variable is the independent variable (IV) and the effect or outcome variable is the dependent variable (DV). The Experiment Independent Variable Manipulation Counterbalancing
Welcome to Seeing Statistics Free Statistics Book Random: Probability, Mathematical Statistics, Stochastic Processes Welcome! Random (formerly Virtual Laboratories in Probability and Statistics) is a website devoted to probability, mathematical statistics, and stochastic processes, and is intended for teachers and students of these subjects. The site consists of an integrated set of components that includes expository text, interactive web apps, data sets, biographical sketches, and an object library. Please read the Introduction for more information about the content, structure, mathematical prerequisites, technologies, and organization of the project. Random is hosted at two sites: www.math.uah.edu/stat/ and www.randomservices.org/stat/.

Every other website or snobbish research paper has not deigned to explain things in words consisting of less than four syllables. I was tossed to and fro like a man holding on to a frail plank that he calls his determination until I came across your electronic textbook...You have cleared the air for me. You have enlightened. You have illuminated. You have educated me." — Mr. "As a professional medical statistician of some 40 years standing, I can unreservedly recommend this textbook as a resource for self-education, teaching and on-the-fly illustration of specific statistical methodology in one-to-one statistical consulting. — Mr. "Excellent book. — Dr. "Just wanted to congratulate whoever wrote the 'Experimental Design' page. — James A.

ModernDive Getting Started - For Students This book was written using the bookdown R package from Yihui Xie (Xie 2016). In order to follow along and run the code in this book on your own, you’ll need to have access to R and RStudio. You can find more information on both of these with a simple Google search for “R” and for “RStudio.” An introduction to using R, RStudio, and R Markdown is also available in a free book here (Ismay 2016). It is recommended that you refer back to this book frequently as it has GIF screen recordings that you can follow along with as you learn. We will keep a running list of R packages you will need to have installed to complete the analysis as well here in the needed_pkgs character vector. You can run the library function on them to load them into your current analysis. Colophon The source of the book is available here and was built with versions of R packages (and their dependent packages) given below.
MA121: Introduction to Statistics Probabilities affect our everyday lives. In this unit, you will learn about probability and its properties, how probability behaves, and how to calculate and use it. You will study the fundamentals of probability and will work through examples that cover different types of probability questions. These basic probability concepts will provide a foundation for understanding more statistical concepts, for example, interpreting polling results. Though you may have already encountered concepts of probability, after this unit, you will be able to formally and precisely predict the likelihood of an event occurring given certain constraints. Probability theory is a discipline that was created to deal with chance phenomena. The skill of calculating probability allows us to make better decisions. We will also talk about random variables.

Probability & Statistics Probability & Statistics [Enter Course] Overview: This course introduces students to the basic concepts and logic of statistical reasoning and gives the students introductory-level practical ability to choose, generate, and properly interpret appropriate descriptive and inferential methods. We offer two versions of statistics, each with a different emphasis: Probability and Statistics and Statistical Reasoning. One of the main differences between the courses is the path through probability. In-Depth Description There are two versions of the OLI Statistics course: Probability and Statistics and Statistical Reasoning. Unit 1 Exploratory Data Analysis. Unit 2 Producing Data. Unit 3 Probability. Unit 4 Inference. The course is built around a series of carefully devised learning objectives that are independently assessed. This course contains only the StatTutor lab exercises.
