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






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






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






5. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






25. A type of reliability - where different versions of same instrument are used and scores are compared






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






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






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






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






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






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






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






33. 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






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






35. 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)






36. 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.






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






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






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






40. Bar graph that shows frequency distributions






41. 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






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






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






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






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






46. 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.






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






48. Type of line graph that shows frequency distributions






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






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