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






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






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






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






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






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






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






8. 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.






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






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






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






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






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






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






15. Perception of relationship where none exists.






16. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






31. 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






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






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






34. Experimental factor that is manipulated; variable whose effect is being studied.






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






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






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






39. 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.






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






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






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






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






44. 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






45. Bar graph that shows frequency distributions






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






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






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






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






50. 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.
