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






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






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






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






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






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






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






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






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






10. 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.






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






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






13. Type of line graph that shows frequency distributions






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






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






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






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






18. 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.






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






20. Arithmetic average of a distribution -






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






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






23. 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)






24. 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






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






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






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






28. Testable and falsifiable prediction - often implied by a theory






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






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






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






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






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






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






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






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






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






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






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






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






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






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






44. 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






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






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






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






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






49. 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.






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