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






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






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






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






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






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






7. 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.






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






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






10. 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






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






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






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






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






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






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






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






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






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






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






21. Bar graph that shows frequency distributions






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






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






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






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






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






27. 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






28. 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






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






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






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






32. The tendency for people to behave differently when they know they are being studied






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






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






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






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






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






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






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






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






41. View that science flourishes through observation and experiment.






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






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






44. Type of line graph that shows frequency distributions






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






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






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






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






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






50. Arithmetic average of a distribution -
