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






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






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






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






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






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






7. Bar graph that shows frequency distributions






8. 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






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






10. 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.






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






12. 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






13. 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.






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






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






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






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






18. 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)






19. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






37. Perception of relationship where none exists.






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






39. 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






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






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






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






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






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






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






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






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






48. Arithmetic average of a distribution -






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






50. Results of experiment are SIGNIFICANT - they are not likely caused by chance
