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






2. Bar graph that shows frequency distributions






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






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






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






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






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






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






9. 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






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






11. Factors in an experiment that are unchanged for both the control group and the experimental group






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






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






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






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






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






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






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






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






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






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






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






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






24. 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






25. 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.






26. View that science flourishes through observation and experiment.






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






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






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






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






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






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






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






34. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






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






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






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






45. 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)






46. 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






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






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






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






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