Question

The durability of a plastic product is directly affected by the hardness of the plastic types used. Plastic hardness which is measured with the Durometer Hardness test goes between 0 and 100. A higher number represents a harder plastic. A comparative test is conducted to investigate the quality of the plastic based on their hardness from 3 different factory sources. The test is conducted with 6 different plastic types acquired from each factory source. The types of plastic are sorted based on the nature of hardness in ascending order.
