Chicken Weights by Feed TypeAn experiment was conducted to measure and compare the effectiveness of various feed supplements on the growth rate of chickens. Usagechickwts FormatA data frame with 71 observations on the following 2 variables.
DetailsNewly hatched chicks were randomly allocated into six groups, and each group was given a different feed supplement. Their weights in grams after six weeks are given along with feed types.
