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. 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






2. 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






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






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






5. View that science flourishes through observation and experiment.






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






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






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






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






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






12. Arithmetic average of a distribution -






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






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






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






16. 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






17. Bar graph that shows frequency distributions






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. Percentage of scores falling at or below a specific score.






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






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






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






38. Type of line graph that shows frequency distributions






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






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






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






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






43. 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)






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






45. 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.






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






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






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






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






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