0 / 2 pts Which one of Cook and Campbell's (1979) four big validities best addresses random selection?    external      internal – WRONG      construct      statistical – MAYBE?     Question 3 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 4 2 / 2 pts Consumer skills are useful when reading:    popular press coverage of research      news articles      research articles      all of these

   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 – WRONG     Incorrect Question 8 0 / 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 – WRONG      construct      statistical     Question 9 2 / 2 pts According to your assigned reading this week, the four validities approach improves:    setting of priorities      critical thinking skills      ability to evaluate claims      all of these     Question 10 2 / 2 pts Which of the following should begin on a new page?    Method

     Results      Appendix      Discussion     Incorrect Question 11 0 / 2 pts Which of the following should NOT be included on the Title page?    running head      byline      key words      page number – WRONG     Question 12 2 / 2 pts Which of the following provides an estimate of the effect the variables of interest have on one another regardless of sample size?    power      alpha      effect size      p value     Question 13

page number     Question 16 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 17 2 / 2 pts In general, the ____________ the expected effect, the ________________ the required sample size.    larger ; larger      smaller; larger      smaller; smaller      cannot determine with the information provided     Question 18 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 19 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 20 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 21 2 / 2 pts Using Cohen's conventions, an effect size of .50 is interpreted as:

    Question 24 2 / 2 pts The very first page in a research paper is:    Introduction      References      Abstract      Title page     Question 25 2 / 2 pts If power is 90%, this implies that you have:    a 90% chance of making a Type I error      a 90% chance of making a Type II error      a 90% chance of finding significance given a real effect      a 10% chance of making the correct decision     Question 26 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   Quiz Score:  40  out of 50
