(8.) If a test of a null hypothesis is directional (one-tailed) rather than nondirectional
(two-tailed), then the power of the test increases.
Each tester revealed epistasis in a different group of [F.sub.2] individuals and epistasis was nondirectional
. Regression analyses revealed no association between epistatic contribution and testcross yields of [F.sub.3] or backcrosses of [F.sub.2] plants to parents.
The variance due to measurement error varied between 10% and 14% of the nondirectional
asymmetry variance, except for LM/3 for which the proportion was around 23%.
heterogeneity tests to evaluate simply ordered alternative hypotheses.
Because of the possibilities for a positive, negative, or even a nonlinear relationship between frequency and communication quality, we offer a nondirectional
The first argument assumes that interfirm similarity judgments are nondirectional
. Lant and Baum (1994), for example, observed that Manhattan hotels defined as rivals those other hotels closest in price, location, and size to their own.
In statistics, one weak standard is the nondirectional
The following nondirectional
hypothesis is offered to determine the type of turnover being experienced.
In summary, the research hypothesis addressed in this study may be stated in nondirectional
alternative form as follows:
The uplink designs of the six systems vary, but most call for nondirectional
receive antennas, allowing automotive installation using small flush-mounted modules in the car roof.
Table 3 COMPARISON OF PROPERTIES OF WOVEN AND NONWOVEN FABRICS Properties Woven Nonwoven Fiber arrangement Orthogonal Random Properties Directional Nondirectional
Breaking Strength Higher Lower Breaking Elongation Lower Higher Initial Modulus Higher Lower Tear Resistance Lower Higher Openings Can be regular Irregular Filtration Single layer Often multilayer Porosity 35% to 45% 55% to 93% Inplane flow Low Can be high Edge May ravel Does not ravel Source: Raumann, G., "Geotextiles: Construction materials in evolution," p.10-15, proceedings of Second International Conference on Geotextiles, Aug.
Thus, there was no empirical support for a directional hypothesis and the nondirectional
hypothesis of no differences was examined.
