Scruggs holds a Master of Arts in psychology from Columbia University and is working to obtain her doctorate in clinical psychology at Alliant International University. endobj Generally, a moderate to large effect size of 0.5 or greater is acceptable for clinical research. Finding a balance between confidence and an achievable research goal is crucial. There are certain factors to consider, and there is no easy answer. endobj Our free calculator uses the following equation. 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 will be statistically significant and due to the manipulation or treatment.
