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






2. 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






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






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






5. 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.






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






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






8. Descriptive research technique in which one person or a small group is studied in depth in hope of revealing universal principles






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






10. 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.






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






12. 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






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






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






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






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






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






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






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






20. 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)






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






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






23. 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.






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






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






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






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






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






29. Type of line graph that shows frequency distributions






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






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






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






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






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






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






36. Bar graph that shows frequency distributions






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






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






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






40. 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






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






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






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






44. Perception of relationship where none exists.






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






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






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






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






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






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