- Nóta The value of the coverage factor k is chosen on the basis of the desired level of confidence. Typically, k is in the range 2 to 3. Because enough experiments were done so the degrees of freedom do not affect the coverage factor, in the present case k = 2 was chosen, so the value of the measurand will lie within that range (+ U) with 95% confidence.
