  1. External validity
    the generalization of the results in a study
  2. Scientific Method
    • method of solving problems that uses the following steps
    • 1. defining problem
    • 2. Hypothesis
    • 3. gather data
    • 4. analze data 5. interpreting data
  3. independent Variable
    • the part of the experiment being manipulated,
    • also called experimental or treatment
  4. Analytical research
    • type of research that involves in-depth study and evaluation of available information in an attempt to explain complex phenomena
    • 1.historical
    • 2. philosophical
    • 3 reviews
    • 4. resource synthesis 
  5. Experimental research
    • type of research that involves the manipulation of treatments in an attempt to establish cause and effect relationships
    • type of research that can manipulate treatments and establish a cause and effect
  6. Internal Validity
    the extent to which the results for a study can be attributed to the treatments used in study
  7. Hypotheis
    educated guess
  8. Dependent Variable 
    • The effect of Independent variable
    • yield 
  9. Ecological Validity
    • Does the seeing have enough of the real-world characteristics to allow generalization to reality 
    • The research setting perceived by the research participant in the way intended by the experimenter 
  10. Basic Reseach
    • Goal: theory driven
    • Approach : laboratory 
    • deal with theoretical concepts, has no immediate concern with application  done just for knowledge
  11. Applied Research
    • Goal: immediate solutions
    • Approach: real- world settings
    • done with a specific question or application in mind
  12. Descriptive Research
    • Concerned with status
    • to describe the status of the study's focus
    • Common techniques are questionares  interviews, normative survey, case studies, job analysis, observational research 
  13. Primary Source
    • First hand source of data in research
    • original study
  14. Secondary Research
    Source of data in research in which an author has evaluated and summarized previous research 
  15. Nominal scale
    Unorganized categories (gender, religion, party)
  16. Ordinal scale
    • Ordered categories
    • Differences between adjacent scores are not equal
    • Ranked order, cant quantify 
  17. Interval scale
    • difference between adjacent score are equal
    • An arbitrary zero point
    • ie number on a temperature scale, no fixed zero
  18. Ratio Scale
    • There is a fixed Zero
    • i.e weight, height, cant go below zero
  19. Levels of measurement
    • Classification system for the types of variables that we encounter research
    • 1Nominal 2Ordinal 3Interval 4Ratio
  20. Between-groups/ between participants/ independent design
    Research designs where different participants are allocated to each of the conditions of the study
  21. Within-groups/ participants design
    Research designs where one group of participants takes part in all conditions of the study
  22. Randomized Control Trial
    • Study where participants are randomly assigned to an intervention and control condition and that includes blinding of all people likely to introduce bias in the study
    • Gold standard
  23. Concepts
    idea about phenomena of interest 
  24. Evidence-based practice
    • Treatments and procedures which are based upon research evidence
    • Looking at the available research on a given topic and subsequently basing plans, behaviors, and decisions
  25. Experiment Design
    • a type of design where the researcher manipulates an independent variable to see what effect this has on a dependent variable
    • best for establishing causal links between variables
  26. Confounding Variable
    variable that are not centered to your study, but which may be responsible for the effect
  27. Quasi- experimental research
    • Investigate differences between intact groups 
    • i.e females males, those diagnosed with a disease compared to those without a disease
  28. Counter balancing
    to get rid of bias in a study where half the participants are presented with one order of condition and the other half with the reverse order of condition
  29. correlational designs
    • designs which measure variable to see how they are related 
    • the relationships between variables
  30. Causation
    what causes variable of interest to change?
  31. Categorical variables
    variables that are made up of categories and involve frequency counts
  32. Continuous variables
    variables that can take on any value on a scale and are not limited to whole numbers 
  33. Discrete variables
    variables that are measured using a whole number scale 
  34. operationalize 
    process of deciding how to measure a concept 
  35. Variable
    measured concepts
  36. Jargon
    Special language that is regularly used in a particular field but which may not be meaningful to people outside the field
