An Introduction To Experimental Design And Statistics For ...
A test like this, in which the alternative hypothesis predicts the direction of the
effect, is called a one-tailed or a one-sided test because the rejection region now
lies in only one tail of the distribution. The critical value at the 5% significance
level ...

A Gentle Introduction to Stata, Second Edition
A two-tailed test is always more conservative than a one-tailed test, so the
tendency to rely on two-tailed tests can be viewed as a conservative approach to
statistical significance. Stata reports both one- and two-tailed significance for all
the ...

Statistical Methods for Health Care Research
One-Tailed and Two-Tailed Tests The "tails" refer to the ends of the normal curve.
When we test for statistical significance, we want to know whether the difference
or relationship is so extreme, so far out in the tail of the distribution, that it is ...

Experimental Design and Data Analysis for Biologists
This is a one-tailed test, the H0 being directional or composite (Barnett 1999),
because only large values of the test statistic at one end of the sampling
distribution will result in rejection of the H0 (Figure 3.1). To do a test with a = 0.05,
then we ...

Statistical Applications for Health Information Management
The probability that the critical value of z (1.64) is less than or equal to the
calculated value of z (-3.2733) for a one-tailed test. z critical one-tail: The critical
value of z (1.64) for a one-tailed test when a = 0.05. It should be interpreted as ±
1.64 ...

Learning to Use Statistical Tests in Psychology
This is whether the research hypothesis is a one-tailed or a two-tailed hypothesis.
A one-tailed hypothesis is one that, as its name implies, makes a prediction in
one particular direction. An example might be that more ideas will be recalled in
a ...

Principles of Medical Statistics
These can easily be halved to denote the one-tailed P values, but the distinctions
must be carefully considered if you want to determine percentiles, to find internal
rather than external probabilities, or to go back and forth from Z values to P ...

When you use PROC TTEST to perform a single-sample t test, the resulting p
value is the probability value for a nondirectional test (i.e., for a two-tailed or ...

Statistical Methods for Psychology
The situation in which we reject H0 for only the lowest (or only the highest) mean
differences is referred to as a one-tailed, or directional, test. We make a
prediction of the direction in which the individual will differ from the mean and our
...

worse and should be avoided. In this situation, the two-tailed test provides an
accepted criterion for when a difference shows the new treatment to be better or
worse. Sometimes, only a one-tailed test is appropriate. Suppose that a new
therapy ...
