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






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






3. 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.






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






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






6. 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






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






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






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






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






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






12. Bar graph that shows frequency distributions






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






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






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






16. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






30. Type of line graph that shows frequency distributions






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






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






33. 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.






34. 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






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






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






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






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






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






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






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






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






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






44. View that science flourishes through observation and experiment.






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






46. Perception of relationship where none exists.






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






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






49. Arithmetic average of a distribution -






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