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






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






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






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






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






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






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






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






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






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






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






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






13. 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)






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






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






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






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






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






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






20. Arithmetic average of a distribution -






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






22. Not rejecting null hypothesis when in fact we should have rejected it - a false negative






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






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






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






26. 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






27. 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






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






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






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






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






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






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






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






35. 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.






36. Occur when the questions asked on a sample survey are confusing or leading






37. 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






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






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






40. 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






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






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






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






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






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






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






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






48. Research project designed to discover degree to which two variables are related to each other






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






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