data

Electrical resistance of battery separators

Format

A data frame with 24 observations on the following 4 variables.

• silica: a factor with levels High Low
• time: a factor with levels High Low
• temp: a factor with levels High Low
• y: a numeric vector

Details

This 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".
