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






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






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






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






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






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






7. 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.






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






9. 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.






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






11. 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






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






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






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






15. View that science flourishes through observation and experiment.






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






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






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






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






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






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






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






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






24. 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)






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






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






27. Measures whether a test looks like it tests what it is supposed to test as determined by a quick look or evaluation by a non expert






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. Association between increases in one variable and decreases in another






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






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






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






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






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






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






36. 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.






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






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






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






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






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






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






43. 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






44. 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.






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






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






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






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






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






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