provides a reliable means of determining whether the variance of a sample is significantly different than that of the population to which it belongs. While the mathematics required to calculate the critical value of F, the point at which variances are significantly different, the calculations...
Choose an appropriate significance level (alpha value). An alpha value of p = .05 is commonly used. This means that the probability that the results found are due to chance alone is .05, or 5%, and 95% of the time a difference found between the control group and the experimental group...
