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






3. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






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






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






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






14. Bar graph that shows frequency distributions






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






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






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






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






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






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






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






22. 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






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






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






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






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






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






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






29. 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)






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






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






32. Perception of relationship where none exists.






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






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






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






36. Arithmetic average of a distribution -






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






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






39. 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.






40. 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.






41. 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.






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






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






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






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






46. Procedure that ensures every person in a population has an equal chance of being chosen to participate






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






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






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






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