Method of strain variance analysis assesses the consistency and variability within materials by examining variations in measurements from multiple subsamples. It calculates within-subsamples variance (consistency) and between-subsamples variance (variability), and uses statistical tools such as degrees of freedom, variance ratio (F-distribution), and confidence intervals to determine if differences are significant or due to chance. This …
