We planned to be able to detect a statistically significant effect with four control patients for every burn patient, using a one-tailed
He has completely rewritten the chapter on regression modeling and added or clarified material on one-tailed
and two-tailed tests, choosing the right statistical tests for a particular study, and programming.
In the case of a 2 x 2 table, along with the Likelihood Ratio and Pearson Chi-square tests, there is also the Fisher's Exact Test, which is based upon the hypergeometric probability and is applicable to either one-tailed
or two-tailed hypotheses, relative risk, and odd ratios.
Because the study represents a replication of a previously tested intervention, we used one-tailed
The value of t-critical will be obtained from the one-tailed
test t-table with a critical error equal to 0.
Statistical Analysis--All tests were one-tailed
unless otherwise noted.
Because our predictions are directional, one-tailed
tests would be appropriate.
A Student's one-tailed
t test was used to detect differences in the means of the subjective and histomorphometric values between the bone marrow and control sites.
The analysis is done using formal test of hypothesis for the difference between two means of financial performances of corporations with three different supervisory board characteristics using both directional one-tailed
and nondirectional two-tailed tests.
All comparisons are two-tailed tests unless directionally hypothesised, in which case the one-tailed
probability is reported.
In three out of cases the p-value for the one-tailed
and two-tailed test was 0.
