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






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






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






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






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






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






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






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






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






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






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






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






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






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






15. Bar graph that shows frequency distributions






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






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






18. 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






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






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






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






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






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






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






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






26. 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.






27. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






35. Extent to which a test yields consistent results - a measure is repeatable






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






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






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






39. 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.






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






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






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






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






44. Indication of how likely a result obtained occurred by chance - expressed as p or sig.






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






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






47. Procedure in which info that could introduce bias the result is withheld from participants - but experimenter will be in full possession of facts






48. Perception of relationship where none exists.






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






50. Arithmetic average of a distribution -
