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






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






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






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






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






6. Arithmetic average of a distribution -






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






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






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






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






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






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






13. 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.






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






15. 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






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






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






18. 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.






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






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






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






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






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






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






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






26. 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






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






28. 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.






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






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






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






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






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






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






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






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






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






38. Data exists in categories that are ordered but differences cannot be determined or they are meaningless. (Example: 1st - 2nd - 3rd)






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






40. Type of line graph that shows frequency distributions






41. Bar graph that shows frequency distributions






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






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






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






45. Correlation where as one variable increases - the other also increases - or as one decreases so does the other. Both variables move in same direction.






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






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






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






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






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