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






2. Perception of relationship where none exists.






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






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






5. Any selection method that results in subset of the population (sample) that is not representative - and/or not random






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






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






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






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






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






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






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






13. 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






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






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






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






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






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






19. 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






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






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






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






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






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






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






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






28. Arithmetic average of a distribution -






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






30. Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition - which is assumed to be an active agent.






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






32. 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.






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






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






35. 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






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






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






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






39. View that science flourishes through observation and experiment.






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






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






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






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






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






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






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






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






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






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






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