Yes No Question 2 2 / 2 pts Consumer skills are useful when reading: popular press coverage of research news articles research articles all of these Question 3 2 / 2 pts Which one of Cook and Campbell's (1979) four big validities best addresses random selection? external internal construct statistical Question 4 2 / 2 pts Based on your assigned readings, if you want to be a better consumer of research information, you should: practice conducting your own studies only read empirical journal articles only read journalistic sources practice via various learning opportunities Question 5 2 / 2 pts Which one of Cook and Campbell's (1979) four big validities best addresses potential confounds in a study? external internal construct statistical Question 6 2 / 2 pts If a journalist does not include all of the information needed to fully evaluate a claim using the four validities, a consumer should: be able to say "I don't know" conclude the journalist left it out because it is a major flaw in the research design conclude the journalist left it out because they don't understand it conclude the journalist left it out because the researcher didn't address it Question 7 2 / 2 pts Which one of Cook and Campbell's (1979) four big validities best addresses whether a study used appropriate operational definitions for their variables of interest? external internal construct statistical Question 8 2 / 2 pts Which of the following is NOT one of Cook and Campbell (1979) four big validities? replicable validity external validity statistical validity construct validity Question 9 2 / 2 pts As suggested in your assigned readings this week, researchers in psychology who are attempting to make a causal claim typically prioritize ________ over ___________ validity. internal; external internal; statistical external; internal construct; internal Question 10 2 / 2 pts If power is set to .80, this implies: that the Type I error is set to .20 that the Type II error is set to .20 that the alpha level is set to .08 that the beta is .80 as well Question 11 2 / 2 pts Which of the following statements is true if when using null hypothesis testing, our p value (in the "sig" column of SPSS output) is 0.051? Reject the null hypothesis Fail to reject the null hypothesis Reject the alternative hypothesis Fail to reject the alternative hypothesis Question 12 2 / 2 pts Statistical power is influenced by: sample size alpha level effect size all of these Question 13 2 / 2 pts Which of the following should begin on a new page? Method Results Appendix Discussion Question 14 2 / 2 pts Which of the following should NOT be included on the Title page? running head byline key words page number Question 15 2 / 2 pts You can lower the likelihood of making a Type I error by: Lowering the alpha level to .01 Raising the alpha level to .10 Having two statisticians interpret the SPSS output None of these options would help Question 16 2 / 2 pts Which of the following statements is true if when using null hypothesis testing, our p value (in the "sig" column of SPSS output) is 0.048? Reject the null hypothesis Fail to reject the null hypothesis Reject the alternative hypothesis Fail to reject the alternative hypothesis Question 17 2 / 2 pts In PSYC 510/515 we've used an alpha value of .05. This is: the probability of making a Type I error the probability of making a Type II error to avoid having too small a sample size to enure a large effect size Question 18 2 / 2 pts The very first page in a research paper is: Introduction References Abstract Title page Question 19 2 / 2 pts Which of the following statements is true if when using null hypothesis testing, our p value (in the "sig" column of SPSS output) is 0.069? Reject the null hypothesis Fail to reject the null hypothesis Reject the alternative hypothesis Fail to reject the alternative hypothesis Question 20 2 / 2 pts Which of the following represents the probability of correctly rejecting the null hypothesis — typically set at 0.8? power alpha effect size p value Question 21 2 / 2 pts If a researcher's statistical test supports the conclusion that their manipulation improved worker morale, what is the likelihood the researcher made the wrong decision if alpha is set to .01? 1% 10% 99% 90% Question 22 2 / 2 pts If the alpha level is set at .01, this implies: the researcher is willing to make a Type I error 1% of the time the researcher is willing to make a Type II error 1% of the time the power of the study is .01 that beta is set to 10% Question 23 2 / 2 pts Which of the following can best help a researcher determine if a statistically significant result is clinically meaningful? alpha level effect size mean and standard deviation directional implication Question 24 2 / 2 pts False report probabilities are rather large in research papers published in our field. Authors such as Cohen (1962) and Szucs and Loannidis (2017) argue that low power in such studies is primarily due to what? too large of an alpha value using one-tailed tests insufficient sample sizes selecting the wrong statistical test to analyze the data Question 25 2 / 2 pts What is the current suggested word count range for an abstract? 150-250 100-200 200-300 300-500 Question 26 2 / 2 pts Which of the following belong on the Abstract page in a professionally formatted paper? running head all belong on the abstract page key words page number Quiz Score: 50 out of 50
