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.

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






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






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






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






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






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






10. 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






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






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






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






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






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






16. Perception of relationship where none exists.






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






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






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






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






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






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






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






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






26. 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.






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






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






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






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






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






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






33. Arithmetic average of a distribution -






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






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






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






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






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






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






40. 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






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






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






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






44. View that science flourishes through observation and experiment.






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






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






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






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






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






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