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. Association between increases in one variable and decreases in another






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






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






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






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






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






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






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






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






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






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






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






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






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






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






16. Arithmetic average of a distribution -






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






18. Perception of relationship where none exists.






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






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






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






22. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






45. 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.






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






47. Type of line graph that shows frequency distributions






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






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






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