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. Arithmetic average of a distribution -






3. 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






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






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






6. Perception of relationship where none exists.






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






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






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






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






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






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






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






15. Graphed cluster of dots - each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables.






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






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






18. 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.






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






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






21. Hypothesis that predicts NO relationship between variables. The aim of research is to reject this hypothesis






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






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






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






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






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






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






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






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






30. 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.






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






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






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






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






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






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






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






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






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






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






41. Type of line graph that shows frequency distributions






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






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






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






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






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






47. 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)






48. Bar graph that shows frequency distributions






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






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