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






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






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






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






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






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






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






8. 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






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






10. 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.






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






12. Bar graph that shows frequency distributions






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






14. 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






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






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






17. 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)






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






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






20. Research in which the same people are re-studied and re-tested over a long period






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






22. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






36. 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






37. 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.






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






39. Arithmetic average of a distribution -






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






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






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






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






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






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






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






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






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






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






50. Type of line graph that shows frequency distributions
