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






2. Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition - which is assumed to be an active agent.






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






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






5. Graphed cluster of dots - each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables.






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






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






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






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






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






11. Middle score in a distribution; half scores are above it and half are below it.






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






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






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






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






16. 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.






17. Sample that fairly represents a population because each member has an equal chance of inclusion.






18. 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)






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






20. A test is divided into 2 halves and scores on the halves are compared to see if test is consistent within itself. Ex. compare odds & evens






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






22. 'Fake subjects' that look & behave like real subjects in study.






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






24. We overestimate our accuracy and our changes of success and ability to predict and explain






25. Descriptive research technique in which one person or a small group is studied in depth in hope of revealing universal principles






26. Research in which the same people are re-studied and re-tested over a long period






27. Skewed distribution with many more scores on the higher end of the distribution






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






29. Bell-shaped curve that results when values of a trait in a population are plotted against their frequency






30. Skewed distribution where data has many more scores toward the lower end of the distribution






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






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






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






34. Extent to which a test measures or predicts what it is supposed to - test accuracy






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






36. Variable that may change in response to manipulations of the IV (what is measured)






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






38. 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






39. Variables other than IV that participants in - one group have that makes them different - from the other group. Two variables linked together in a way that makes it difficult to sort out their specific effects.






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






41. Researchers takes subjects & conditions as they naturally occur - with little if any control over what happens. no random assignment so no cause and effect can be determined






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






43. In a normal distribution it tells you how far a number is above or below mean in terms of standard deviations.






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






45. Tendency to give socially approved answers to questions about oneself.






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






47. Any selection method that results in subset of the population (sample) that is not representative - and/or not random






48. Perception of relationship where none exists.






49. Percentage of scores falling at or below a specific score.






50. Differences between values can be found - but is NO absolute ZERO. Examples: temperature F - time
