Web3 nov. 2024 · Homogeniteit van variantie (homogeneity of variance) Het is belangrijk om eerst naar de variantie te kijken, voordat je een parametrische toets uitvoert. Deze toetsen gaan meestal gepaard met assumpties of aannames, zoals homogeniteit van variantie ( homogeneity of variance ). Web23 jun. 2011 · Electrochemical impedance spectroscopy (EIS) may be used in the characterization of membrane capacitance, resistance, dielectric constant, and surface homogeneity. Moreover, EIS has been used previously to determine the membrane bulk resistance [ 15 ], as well as the membrane bulk capacitance ( Equation 1 ) [ 8 , 16 ].
WebSome statisticians suggest never using Bartlett's test. It is too sensitive to minor differences that wouldn't really affect the overall variance. So if the difference in variances is not huge, and especially if your sample sizes are equal (or nearly so), you might be safe just ignoring Barlett's test.
