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. Procedure for statistically combining results of many different research studies






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






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






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






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






6. 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.






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






8. Experimental procedure in which both research participants and research staff are ignorant about whether the research participants have received the treatment or a placebo.






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






10. Bar graph that shows frequency distributions






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






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






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






14. 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.






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






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






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






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






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






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






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






22. 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)






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






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






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






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






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






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






29. 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






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






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






32. 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.






33. Perception of relationship where none exists.






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






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






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






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






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






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






40. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






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






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






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