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






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






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






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






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






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






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






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






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






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






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






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






13. 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






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






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






16. Type of line graph that shows frequency distributions






17. 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.






18. Extent to which a test yields consistent results - a measure is repeatable






19. 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






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






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






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






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






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






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






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






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






28. 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.






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






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






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






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






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






34. 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.






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






36. 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






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






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






39. 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.






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






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






42. Indication of how likely a result obtained occurred by chance - expressed as p or sig.






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






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






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






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






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






48. 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)






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






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