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






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






3. Variable that may change in response to manipulations of the IV (what is measured)






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






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






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






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






8. 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.






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






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






11. Arithmetic average of a distribution -






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






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






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






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






16. Type of line graph that shows frequency distributions






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






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






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






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






21. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






41. 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






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






43. Bar graph that shows frequency distributions






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






45. Measuring device or procedure designed to measure psychology-related variables. A measurement that results in a score or result that is standardized






46. 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






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






48. 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.






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






50. Statement of procedures used to explain research variables in enough detail to allow for replication
