  6. Syllabus • Work Habits • Read • Due dates are non-negotiable • Attempt practice items at end of chapters • If you struggle with the items see tutors ASAP. • Bring a calculator • Follow class examples • Passive learning does not work • Other course policies • Religious accommodations • Disabilities • Inform and provide documentation

  7. Who is here? • In groups of three or four • Identify yourself and get to know one another • Ask the following questions • What are your professional experiences? • What is your program of study? • What topics within your program interest you? • What is your favorite recreational activity? • Be prepared to introduce one member of your group. • Exchange email addresses and/or phone numbers • Contact if you miss class. • Bounce ideas • New friends • Misery loves company ;-)

  8. How to study & learn statistics: • Statistics is a Language • Read the textbook • Do the practice problems with each chapter (odd problems) • Distributed Practice • Studying once a week does not work • Use the tutors and my office hours • Don’t get behind & don’t wait to say you don’t understand

  9. How to study & learn statistics: • This is not a Cookbook Course -- I want you to know why we do what we do even more than how we do what we do. You can always look up how; but errors in research are made at the "why" level, not the "how" level.

  10. Working with your feelings & attitudes • HIGH ANXIETY! • Try to put your math fears aside. • You have the basic math skills. • Some people think the whole process is hogwash (Suspend your Disbelief!) • I cannot promise scintillation or excitement; this will be intellectually taxing. • Some people like my methods and some don't.

  11. The Big Picture: Statistics in Context • There are many different research processes • Each has its own: • Philosophies of Inquiry • Methods of Inquiry • Purposes for doing research • Processes and “Rules” • Statistics does not fit them all. • Here is one process:

  12. EDPSY 511: The Big Lessons • Statistics is a language • Statistics is a tool • Statistics is reasoned argument • Statistics and facts are not the same things

  13. Chp. 1 • Key points • Statistics is a process of collecting data in a scientific manner and making decisions based on these data. • Personal experience vs. systematic empiricism • Personal experience if useful BUT • Subject to bias • Can be haphazard • Systematic empiricism • Systematic observation • Control of bias • Replicable

  14. Fundamentals of Research • Answering empirical questions • Observable by the senses. • Publicly verifiable knowledge • Operational definitions • Direct replication • Identical conditions • Systematic replication • Similar conditions

  15. Variables • Variables • Characteristics that takes on different values • Achievement • Age • Condition • Independent variable (IV) • Manipulated or Experimental • Condition • Subject • Personality • Gender • Dependent variable (DV) • The outcome of interest • Achievement • Drop-out status

  16. Populations vs. Samples • Population • The complete set of individuals • Characteristics are called parameters • Sample • A subset of the population • Characteristics are called statistics. • In most cases we cannot study all the members of a population

  17. Descriptive vs. Inferential • Descriptive statistics • Summarize/organize a group of numbers from a research study • Inferential statistics • Draw conclusions/make inferences that go beyond the numbers from a research study • Determine if a causal relationship exists between the IV and DV

  18. Random Sampling vs. Random Assignment • Simple random sampling • Each member of the population has an equal likelihood of being selected. • Helps ensure that our sample will represent the population of interest. • Random assignment • Assigning subjects to different conditions in a way that they have equal chance of being placed in either condition. • Controls for confounding

  19. Goals of Scientific Research • Exploratory • What is out there? • Descriptive • What does this group look like? • Explanatory • Why and how are these constructs related? • Evaluation • Does this program work? • Prediction • Who will become depressed?

  20. Common Research Designs • Correlational • Do two qualities “go together”. • Comparing intact groups • a.k.a. causal-comparative and ex post facto designs. • Quasi-experiments • Researcher manipulates IV • True experiments • Must have random assignment. • Why? • Researcher manipulates IV

  21. A little on SPSS • The assignments require hand calculations and SPSS practice • Typically I have you check your answers using SPSS • Do not buy SPSS • Do not leave the SPSS work for night before the due date. • You will need a TEC center account • Do that after class today
