Relying on effect size as a measure of practical significance is turning out to be just as misleading as using p-values to determine the effectiveness of interventions for improving clinical practice in complex organi- zations such as schools. This article explains how effect sizes have misdirected...
To determine a sample size that will provide the most meaningful results, researchers first determine the preferred margin of error (ME) or the maximum amount they want the results to deviate from the statistical mean. It's usually expressed as a percentage, as in plus or minus 5 percent. R...
We can't help with the "is this correct" because that is predicated on the scientific question at hand and something only you and subject-matter experts can determine. If you are naive to statistics and their role in your analysis, I suggest you consult a statistician...
Don't let your research project fall short - learn how to choose the optimal sample size and ensure accurate results every time.
(size of a stock market of the country a firm is located in). Both variables correlate by 0.5. My hypothesis is that both variables have a negative effect on the dependent variable. To cope with the high correlation I created a interaction effect of the two variables and ...

Of the various methods used to determine the density of a solid material, hydrostatic weighing is the preferred because it is the most accurate, if not the most convenient. Most solid materials of interest are not in the form of neat geometric shapes with easily calculated volumes, requ...

Without estimating that path it is impossible to test the mediational hypothesis. Moreover, it is impossible to determine the size of the effect of DIG on PGA, if indeed there is any. 4. “Think of Many Ways” and inconsistent mediation Vaughn, 1999, Sanna and Schwarz, 2004, and Chang ...
