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






2. 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.






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






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






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






6. Arithmetic average of a distribution -






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






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






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






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






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






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






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






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






15. 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)






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






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






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






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






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






21. 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






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






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






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






25. Bar graph that shows frequency distributions






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






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






28. 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






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






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






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






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






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






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






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






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






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






38. 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






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






40. 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.






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






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






43. Perception of relationship where none exists.






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






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






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






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






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






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






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