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






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






3. Condition of experiment that exposes participants to treatment - that is - to one version of the IV






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






5. 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






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






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






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






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






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






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






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






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






14. 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






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






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






17. 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






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






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






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






21. 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)






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






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






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






25. The probability level which forms basis for deciding if results are statistically significant (not due to chance).






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






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






28. 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.






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






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






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






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






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






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






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






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






37. Bar graph that shows frequency distributions






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






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






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






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






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






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






44. 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






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






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






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






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






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






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