Question: What effect does smoking have on performance Spilich June and
What effect does smoking have on performance? Spilich, June, and Renner (1992) asked nonsmokers (NS), smokers who had delayed smoking for three hours (DS), and smokers who were actively smoking (AS) to perform a pattern recognition task in which they had to locate a target on a screen. The dependent variable was latency (in seconds). The data are presented below. Plot the resulting means and run the analysis of variance. On the basis of these data is there support for the hypothesis that smoking has an effect on performance?
Answer to relevant QuestionsIn the study referred to in Exercise 16.20, Spilich et al. (1992) also investigated performance on a cognitive task that required the participant to read a passage and then to recall it later. This task has much greater ...Use MYSTAT or LazStats to reproduce the analysis in Exercise 16.23. The data follow. What would happen if the sample sizes in Exercise 16.7 were twice as large as they were? If you go back to Exercise 16.2, you will see that it really forms a 2 3 2 factorial. Run the factorial analysis and interpret the results. (The data are reproduced here.) Data in Exercise 17.1.
