FIGURE 4.11
SPSS input for three-search-engine hypothesis test.
The analysis process is the same as earlier when we had two search engines. The out-
put is in Figure 4.12 , and you can note that the Fisher exact test is not part of the output.
The p -value equals 0.010 (“Sig.,” see arrow in Figure 4.12 ), which, of course,
is the same value provided by the Excel analysis, but rounded to three digits. As we
noted in the previous section, this is less than 0.05, the traditional cutoff point, and
therefore, we reject H0 and conclude that the pass/fail rates are not the same for task
1 for the three search engines.
