From: Reproducibility and repeatability of measuring the electrical impedance of the pregnant human cervix-the effect of probe size and applied pressure

Figure 4

Repeatability and reproducibility standard deviations for cervical resistivity by probe and force of application. Repeatability (one observer) and reproducibility (two observers) standard deviations for cervical resistivity derived by both the 3 mm and 12 mm probes applied to the cervix softly (0.8 Newton) and firmly (2.2 Newton).
