41)Which statement is the most accurate? A)For each research design, there is only one appropriate statistical test. B)For each research design, there may be more than one appropriate statistical test, although they generally lead to the same conclusions. C)For each research design, there are many appropriate statistical tests that always lead to the same conclusions. D)For each research design, there are two appropriate statistical tests, and they generally lead to different conclusions. 42)Which of the following is NOT listed in the text as an example of secondary analyses? A)Data snooping. B)Post hoc analyses. C)Ex post facto analyses. D)Analyses designed to help explain the pattern of results. 43)Post hoc analyses A)are unplanned and therefore should not be used. B)can be useful in elaborating the meaning of planned analyses. C)are completed after the research article has been published. D)are completed after secondary analyses have been completed. 44)When research produces unexpected results, ________ analyses may be used to help explain the results. A)discrepancy B)ancillary C)filibuster D)secondary 45)Data snooping is A)referring to data or research that has not been published. B)changing the hypothesis of a study after the data have been collected and analyzed. C)used most often in large scale, lower-constraint research when clues to potential relationships between variables may be buried in the mass of data. D)used to control confounding variables in experimental research. 46)Monte Carlo studies continue to show the remarkable robustness of most statistics to assumption violations, particularly A)when the sample sizes are large. B)when the sample sizes are equal. C)for nonparametric statistics. D)when the sample sizes are small. 47)If an assumption of a statistical test can be violated without threatening the validity of the conclusions drawn, the test is said to be ________ to violations of that assumption. A)withstanding B)robust C)strong D)powerful 48)In a study in which scores on a math test are being used as a dependent variable, the researcher discovers that the scores are positively skewed. This violates the assumption of normality for the t-test that the researcher planned to use. The best solution for the researcher is to A)not use the t-test because the results may not be valid. B)use another test that does not have the same assumptions. C)check if the t-test is robust to violations of normality. D)prorate the data so it fits a normal curve. 49)If a data set violates an assumption of the statistical test that is to be used, the test should be ________ to this violation if we want to be confident that our conclusions are valid. A)robust B)withstanding C)strong D)powerful 50)The series of studies that showed many statistical tests to be robust to violations of assumptions on which they are based are known as A)Reno studies. B)robust studies. C)violation studies. D)Monte Carlo studies. Â
