Research Methods

Subject : business-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Skewed distribution where data has many more scores toward the lower end of the distribution






2. Method by which participants are misinformed or misled about study's methods and purposes - must be told truth about this in debriefing






3. Form of validity in which a psychological measure is able to predict some future behavior or is meaningfully related to some other measure






4. Measuring device or procedure designed to measure psychology-related variables. A measurement that results in a score or result that is standardized






5. Measures whether a test looks like it tests what it is supposed to test as determined by a quick look or evaluation by a non expert






6. Giving participants in a research study a complete explanation of the study after the study is completed needed for deception






7. Research method in which investigator manipulates one or more factors (IV) to observe effect on some behavior or mental process (DV)






8. Statement of procedures used to explain research variables in enough detail to allow for replication






9. Testable and falsifiable prediction - often implied by a theory






10. Change in subject's behavior caused simply by awareness of being studied






11. Data exists in categories that are ordered but differences cannot be determined or they are meaningless. (Example: 1st - 2nd - 3rd)






12. Difference between highest and lowest scores in a distribution.






13. Arithmetic average of a distribution -






14. Repeating of research study to determine if its finding extends to other participants and circumstances






15. Research project designed to discover degree to which two variables are related to each other






16. Statistical method for making simultaneous comparisons between two or more means






17. A research method that looks like an experiment BUT subjects are not randomly assigned to control and experimental groups (no cause and effect can be drawn)






18. Experimental procedure in which both research participants and research staff are ignorant about whether the research participants have received the treatment or a placebo.






19. The tendency for people to behave differently when they know they are being studied






20. In-depth - intensive investigation of individual or small group of people which involves interviews and personal interpretations by researcher. It may also be supplemented with psychological or medical tests






21. Hypothesis that predicts NO relationship between variables. The aim of research is to reject this hypothesis






22. Computed measure of how much scores vary around the mean score.






23. Perception of relationship where none exists.






24. All cases in a group - from which samples may be drawn for a study






25. Symbol used to represent the total number of subjects in a research study






26. Data of categories only. Data cannot be arranged in an ordering scheme. (Gender - Race - Religion)






27. The probability level which forms basis for deciding if results are statistically significant (not due to chance).






28. Condition of experiment that exposes participants to treatment - that is - to one version of the IV






29. Sample drawn in such a way that known subgroups within a population are represented in proportion to their numbers in general population






30. Condition of experiment that contrasts with experimental condition and serves as a comparison for evaluating the effect of the treatment.






31. Relationship that exists when one set of data values increases while the other decreases






32. Symbol used for Pearson Correlation Coefficient ranges from -1.0 to +1.0






33. Subset of a population in which every element in the population has an equal chance of being selected






34. A type of reliability - where different versions of same instrument are used and scores are compared






35. Expectations by researcher that might influence results of experiment or its interpretation






36. Rejecting null hypothesis when it is actually true - a false positive






37. Type of line graph that shows frequency distributions






38. Assigning participants to experimental and control conditions by chance - thus minimizing preexisting differences between those assigned to different groups.






39. Perception of a correlation between variables where none exists.






40. Assigning participants to experimental and control conditions by chance - thus minimizing preexisting differences between those assigned to the different groups






41. Experimental factor that is manipulated; variable whose effect is being studied.






42. Tendency to believe - after learning an outcome - that one would have foreseen it.






43. If you take the same test 2x's & you get the same results it shows ______ reliability






44. Variable not relevant to what you are studying that has unplanned effect on DV. It may influence results - but all conditions are effected so it does not create bias.






45. Statement that describes how to measure a particular variable or define a particular term specifically in a study






46. Factors in an experiment that are unchanged for both the control group and the experimental group






47. Research method in which info is obtained by asking many individuals a fixed set of questions






48. More than one individual scores same test - regardless of who rates test - scores should be the same for _____ reliability






49. Set of assumptions used to explain phenomena & offered for scientific study






50. When a specific word used in a question affects how respondents answer the question or the order of the questions
