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






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






3. Method by which participants are misinformed or misled about study's methods and purposes - must be told truth about this in debriefing






4. Perception of relationship where none exists.






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






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






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






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






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






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






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






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






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






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






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. 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






18. 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






19. 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






20. Type of line graph that shows frequency distributions






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






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






23. 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.






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






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






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






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






28. Bar graph that shows frequency distributions






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






30. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






48. 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)






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






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