Inferential statistics allow for the calculation of the probability that any observed difference between two research samples is due to chance or random variation. This information is used to determine whether the observed difference is statistically significant or not, providing guidance on whether the difference is likely to be meaningful or just a chance occurrence. Skewed distributions, percentile scores, and bar graphs do not provide this level of insight into the significance of observed differences.
