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






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






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






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






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






6. 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






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






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






9. Bar graph that shows frequency distributions






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






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






12. Arithmetic average of a distribution -






13. 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.






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






15. Variables other than IV that participants in - one group have that makes them different - from the other group. Two variables linked together in a way that makes it difficult to sort out their specific effects.






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






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






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






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






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






21. View that science flourishes through observation and experiment.






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






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






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






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






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






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






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






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






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






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






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






33. 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.






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






35. 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)






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






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






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






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






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






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






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






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






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






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






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






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






48. Perception of relationship where none exists.






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






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