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






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






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






4. Any selection method that results in subset of the population (sample) that is not representative - and/or not random






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






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






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






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






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






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






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






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






13. 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.






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






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






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






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






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






19. 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






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






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






22. 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






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






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






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






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






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






28. 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.






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






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






31. If you take the same test 2x's & you get the same results it shows ______ reliability






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






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






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






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






36. Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition - which is assumed to be an active agent.






37. 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






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






39. Perception of relationship where none exists.






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






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






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






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






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






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






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






47. 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.






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






49. We overestimate our accuracy and our changes of success and ability to predict and explain






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