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. Arithmetic average of a distribution -






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






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






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






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. 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.






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






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






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






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






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






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






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






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






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






16. Bar graph that shows frequency distributions






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






18. Tendency to overestimate extent to which others share our beliefs and behaviors






19. 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)






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






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






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






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






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






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






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






27. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






42. 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






43. 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.






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






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






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






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






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






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






50. Perception of relationship where none exists.
