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






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






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






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






5. Type of line graph that shows frequency distributions






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






7. 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.






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






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






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






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






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






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






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






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






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






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






18. View that science flourishes through observation and experiment.






19. 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.






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






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






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






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






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






25. 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






26. Relationship that exists when one set of data values increases while the other decreases






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






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






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






30. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. Bar graph that shows frequency distributions






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






48. 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.






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






50. 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
