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






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






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






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






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






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






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






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






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






10. 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






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






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






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






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






15. Arithmetic average of a distribution -






16. 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.






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






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






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






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






21. 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.






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






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






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






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






26. Bar graph that shows frequency distributions






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






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






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






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






31. Measuring device or procedure designed to measure psychology-related variables. A measurement that results in a score or result that is standardized






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






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






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






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






36. 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






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






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






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






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






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






42. 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






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






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






45. 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.






46. Any selection method that results in subset of the population (sample) that is not representative - and/or not random






47. View that science flourishes through observation and experiment.






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






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






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