    Nondirectional: there is a change but not specific

    • phenomena of interest
    • population
  8. What must you look at within the independent variable?

  12. What type of hypothesis tells us what we specifically expect to change?
  13. During the theory/research relationship, what type of research method is involved if it starts with theory? (quantitative or qualitative??)
  14. During the theory/research relationship, what type of research method is involved when it starts with confirmation? (Quantitative or qualitative??)
    Qualitative (creating a theory about what you saw)
  15. Can a speculation and collection of a proposition prove a theory ?
  16. How do we make sure research was done in a safe well thought out manner that protects humans

  17. What is a situation in which the rights of study participants are in direct conflict with requirements for a rigorous study
    ethical dilemma in conducting research
  18. 3 types of consent

  24. What is written in a positive statement that is included in study that will specifically define our population
  25. What is negative, not included in study that will specifically define our population
  26. what is extending the findings of a sample study to a larger population
  27. what influences a generalization
    quality and consistency of study
  28. What is a repeating study and keeping it as true to the second study to expand info
  29. What is the sample the accessible population, and the target population are alike in as many ways as possible
  30. What needs to be evaluated under representativeness
    • setting
    • characteristic
    • values on variables
  31. what is an error of the difference in the population and the sample? (mean reading)

  32. what is the percentage of subjects that declined to participate in the study
    refusal rate
  33. what is the withdrawal or loss of subjects from a study?
