WebWhen the null hypothesis is true (i.e. the means are equal), MS (Factor) and MS (Error) are both estimates of error variance and would be about the same size. Their ratio, or the F ratio, would be close to one. When the null hypothesis is not true then the MS (Factor) will be larger than MS (Error) and their ratio greater than 1. WebThe two-factors model applied equally well to patients on insulin and those on oral hypoglycemic agents. Likewise, construct reliability based on the formula by Fornell and Larcker 29 was evaluated. The construct reliability estimates describe the variance captured by measurement errors as opposed to the variance attributable to the latent factors. impact fees volusia county florida
