PigFeed
Description
Effects of additives to pig feed on weight gain
Format
A dataset with 12 observations on the following 3 variables.
WgtGain | Daily wight gain (hundredths of a pound over 1.00) |
Antibiotic | Antibiotic in the feed? No or Yes |
B12 | Vitamin B12 in the feed? No or Yes |
Details
A scientist in Iowa was interested in additives to standard pig chow that might increase the rate at which the pigs gained weight. Two factors of interest were vitamin B12 and antibiotics. To perform the experiment, the scientist randomly assigned 12 pigs, three to each of the diet combinations (Antibiotic only, B12 only, both, and neither).
