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






2. Degree to which test is representative of total domain its supposed to cover.






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






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






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






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






7. Procedure for statistically combining results of many different research studies






8. Tendency to overestimate extent to which others share our beliefs and behaviors






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






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






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






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






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






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






15. Statistical measure of strength of association between two variables ranging from -1.0 to 1.0






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






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






18. 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.






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






20. Arithmetic average of a distribution -






21. Bar graph that shows frequency distributions






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






23. View that science flourishes through observation and experiment.






24. Data with an absolute 0. Ratios are meaningful. (Length - Width - Weight - Distance)






25. Series of steps followed to solve problems including collecting data - formulating a hypothesis - testing the hypothesis - and stating conclusions






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






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






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






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






30. 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






31. 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






32. 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)






33. Effects of being born and raised in a particular time or situation where all other members of your group has similar experiences makes your group unique from others






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






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






36. Results of experiment are SIGNIFICANT - they are not likely caused by chance






37. Measure of the extent to which two factors vary together which can be positive or negative or non






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






39. Procedure in which info that could introduce bias the result is withheld from participants - but experimenter will be in full possession of facts






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






41. Extent to which scores suggest that a test is actually measuring an ABSTRACT theoretical idea (such as anxiety - personality - introversion - etc.).






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






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






44. 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






45. 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.






46. 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.






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






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






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






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