| Sample sizes of individual studies varied, ranging from 39 to 220, but tended to be larger than those used in previous work. |
| Sample sizes varied across the questions tested, since all firms did not answer every question. |
| Sample outcome distributions for three key economic indicators were displayed numerically and graphically. |
| Sample transmission of the probe pulses was determined using home-built photodiode detectors combined with a boxcar integrator. |
| Sample sites are located within recent quarry exposures, drainage and road cuttings. |
| Sample workup, hybridization, and analysis were performed as described previously. |
