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






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






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






5. 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)






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






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






8. 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.






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






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






11. 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.






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






13. 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






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






15. Perception of relationship where none exists.






16. Arithmetic average of a distribution -






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






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






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






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






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






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






23. 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.






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






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






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






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






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






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






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






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






32. Extent to which scores suggest that a test is actually measuring an ABSTRACT theoretical idea (such as anxiety - personality - introversion - etc.).






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






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






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






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






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






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






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






40. 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






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






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






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






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






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






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






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






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






49. Bar graph that shows frequency distributions






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