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. Statistical method for making simultaneous comparisons between two or more means






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






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






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






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






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






7. 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.






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






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






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






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






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






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






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






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






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






17. 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






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






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






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






21. Tendency to give socially approved answers to questions about oneself.






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






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






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






25. Perception of relationship where none exists.






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






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






28. 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






29. 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.






30. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






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






39. 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.






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






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






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






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






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






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






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






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






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






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






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