Electrical resistance of battery separators
A data frame with 24 observations on the following 4 variables.
silicaHigh LowtimeHigh LowtempHigh Low yThis experiment was run to study the effect of three process factors on the electrical resistance of a battery separator (extruded from a rubber, oil, and silica mix). Each of the three factors, occur at two levels, designated "High" and "Low".
