21)Given the four hypotheses below, what statistical procedures are appropriate to use? Hypothesis 1: There will be more errors in the hijack condition. Hypothesis 2: Seriousness will be greater in the hijack condition. Hypothesis 3: In the hijack condition there will be an inverse relationship between years of experience and number of errors. Hypothesis 4: In the hijack condition, there will be an inverse relationship between years of experience and seriousness of errors. A)ANOVA for all of the hypotheses B)ANOVA; ANOVA; correlation coefficient; correlation coefficient C)t-test; Pearson r; Spearman r; chi-square D)chi-square; Spearman r; Pearson r; t-test 22)What is the dependent variable and the level of measurement of the dependent variable in a study in which you compare participants (matched for age) on how induced anxiety affects the speed at which they recognize words? A)Speed of word recognition; ratio. B)Age; interval. C)Speed of word recognition; interval. D)Age; ratio. 23)Before carrying out ________ statistics, it is helpful to calculate ________ statistics. A)parametric; nonparametric B)descriptive; preliminary C)inferential; descriptive D)descriptive; inferential 24)The type of model recommended in the text to help the researcher in determining appropriate statistical tests is a A)decision-tree model. B)mathematical model. C)statistical model. D)spread sheet model. 25)The authors of the text suggest a ________ to help the beginning researcher determine appropriate statistical procedures. A)branch-tree model B)decision-tree model C)statistical model D)statistical text 26)Which two statistical tests can give us the same information? A)t-test and two-way ANOVA. B)Spearman r and chi-square. C)Inferential and descriptive statistics. D)t-test and one-way ANOVA. 27)In more complex research, in which there may be several research hypotheses and several dependent measures, A)an analysis of variance (ANOVA) will typically suffice. B)a t-test is sufficient, no matter what the complexities are. C)selection of appropriate statistical tests is better deferred until the data are collected. D)we may need a number of statistical procedures to analyze the data. 28)To use the flowcharts in Chapter 13, we need to A)first complete the study. B)make sure the data analyses are complete. C)provide informed consent feedback to all participants. D)describe the study. 29)The first step in the decision model suggested in the text is to A)determine the type of data. B)determine the number of research hypotheses. C)determine the level of statistical significance. D)describe the research so the major characteristics of the study can be identified. 30)The decision-tree model presented in the book is based on three basic steps necessary for determining appropriate statistical procedures. Which of the following is NOT one of the basic steps? A)Describe the research. B)Identify important characteristics. C)Decide level of significance. D)Based on identified characteristics, make decisions to arrive at statistical test. Â
