The results for these strategies are shown in Table 5 with the number of bets placed (N), the actual return to the betting strategy noted, the expected return of the betting strategy, and the z-test
comparing the actual and expected returns based upon the test established by Gandar et al.
This particular path would be select the output box named "critical ratio for difference" in order to assess the z-test
for every variable in dataset.

Comparing the patient's peak heart rate with the heart rate reserve value yielded a z-test
statistic of 2.
Finally, we used a Z-test
on rank differences and Spearman's test for rank correlation to determine if the COLA rankings differ from nominal data rankings (Spearman, 1904).
New to this edition are exercises using the latest versions of SPSS and Excel based on data sets available online, a chapter on the one-sample Z-test
, mini-SSPS and math primers, and notes to instructors.
Thus, the Z-test
will be used to determine the statistical significance of the difference in two categories, as it was done for AURC (3, and references therein).
Responses were analyzed by frequencies, percentages, and z-test
and common percentage were the statistics used.
To test differences in proportions of juveniles over different sample populations, all five sample populations were compared against each other using a z-test
of significance for two proportions (Baldi & Moore 1996).
To test whether any 2 aggregated odds ratios were significantly different, we used the z-test
described by Altman and Bland (8).
