Statistical significance does not provide information about the effect size or the clinical relevance. Because of that, researchers often misinterpret statistically significance as clinical one. On one hand, a large sample size study may have a statistically significant result but a small effect size.
An HEI distributor is an upgrade from a points-type distributor. ... Ford and Plymouth, installed four-cylinder engines in their cars.he increased efficiency of HEI distributors stemmed from the incorporation of the ignition wire into the distributor cap, reducing degradation of the spark and loss of energy potential.
Considerations. One added bonus of the HEI system is the lack of a coil wire. Not only does this make the spark hotter and more potent, it also eliminates the need to adjust the ignition wires now and again.This happens even with more modern variations to this day.he increased efficiency of HEI distributors stemmed from the incorporation of the ignition wire into the distributor cap, reducing degradation of the spark and loss of energy potential.
