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






2. Bar graph that shows frequency distributions






3. 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)






4. Arithmetic average of a distribution -






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






6. 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






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






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






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






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






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






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






13. Most frequently occurring score(s) in a distribution.






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






15. People of different ages are compared to one another at a single point in time






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






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






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






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






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






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






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






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






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






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






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






27. Relationship between variables in which as one variable increases - the other also increases - OR as one decreases so does the other. Both variables move in the same direction.






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






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






30. Correlation where as one variable increases - the other also increases - or as one decreases so does the other. Both variables move in same direction.






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






32. Association between increases in one variable and decreases in another






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






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






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






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






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






38. 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.






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






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






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






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






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






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






45. Extent to which the findings from one group (or sample) can be generalized or applied to other groups (or population






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






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






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






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






50. Descriptive research that involves observing and recording behavior without trying to manipulate and control the situation.
