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






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






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






4. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






23. 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.






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






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






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






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






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






29. Results of experiment are SIGNIFICANT - they are not likely caused by chance






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






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






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






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






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






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






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






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






38. View that science flourishes through observation and experiment.






39. Type of line graph that shows frequency distributions






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






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






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






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






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






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






46. 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






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






48. 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






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






50. 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)
