3. [16] In order to measure the effect of a storewide sales campaign on nonsale items, the research director of national supermarket chain took a random sample of 13 pairs of stores that were matched according to average weekly sales volume. One store of each pair (the experimental group) was exposed to the sales campaign, and the other member of the pair (the control group) was not. The data over a weekly period are provided in the file SALESCMP.xlxs. a....

QUESTION 1 Researchers are interested in the speed of responses people make to different target finding tasks. They state that reaction time is the time in the unit of milliseconds between the presentation of a stimulus, and the keyboard press made by the individual. This is an operational definition of reaction time. True False QUESTION 2 Some researchers are interested in the cognitive limits to the various tasks air traffic controllers perform. They figure the best way to understand these...

SPSS Homework 1 Instructions: Review and One-Way ANOVAs (40 points) Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups.

3. Reaction time experiment (L. Cai, T. Li, Nishant, and A. van der Kouwe, 1996) The experiment was run to compare the effects of auditory and visual cues on speed of response of a human subject. A personal computer was used to present a "stimulus" to a subject, and the reaction time required for the subject to press a key was monitored. The subject was warned that the stimulus was forthcoming by means of an auditory or a visual cue....
