The analysis uses indicator (0,1) variables to represent the factors with the following baseline categories (factor levels without indicator variables): Sit for Workstation, Close for Distance and Large for Size. The regression model has an R-squared of 80.42%. The Intercept of 9.23 represents the average time for a subject at the traditional workstation (Sit) with Large targets Close together (index of difficulty of 2). When the subjects used the standing workstation (Stand), they had an average time 1.16 seconds higher than the traditional workstation and when they used the treadmill workstation (Walk) the subjects had an average time 2.31 seconds higher than sitting. Therefore, subjects had the lowest times (highest productivity) when using the traditional workstation with both standing and walking degrading performance.
