This dataset is from a study about the strength of a particular type of fiber based on the amount of pressure applied.
data(fiber)
This data frame consists of 30 samples with the following 2 variables measured:
pressure
The amount of water pressure applied (measured in bars); the unique levels are 60, 80, 100, 120, 150, and 200.
tensile
The tensile strength of fiber (measured in N/5 cm).
