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






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






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






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






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






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






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






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






9. 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






10. Type of line graph that shows frequency distributions






11. Hypothesis that predicts NO relationship between variables. The aim of research is to reject this hypothesis






12. 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






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






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






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






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






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






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






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






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






21. Arithmetic average of a distribution -






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






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






24. Extent to which a test yields consistent results - a measure is repeatable






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






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






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






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






29. 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






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






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






32. 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)






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






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






35. 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.






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






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






38. 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.






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






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






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






42. Perception of relationship where none exists.






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






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






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






46. 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.






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






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






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






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