| IOR – interocclusal registration material; n – number; SD – standard deviation; F – variation between sample means/variation within the samples. Tests used: 1. Levene test = to assess equality of variances 2. Shapiro-Wilk test = data distribution for normality 3. One way ANOVA = using f distribution (right-tailed) to testing hypothesis and determining statistical differences between various sub groups. | ||||||||
