Table 2c: DI Water Data Combined.

Table 2 includes the stress and strain values for the DI water control. These samples were subjected to a DI water soak for a total four days. Two sets of ten hairs were subjected to this treatment and split into set 1 and set 2. Table 2 is split into three tables, Table 2a, 2b, and 2c. Table 2a includes the stress and strain values for set 1, Table 2b includes the stress and strain values for set 2, and Table 2c includes the average, standard deviation, and % deviation for set 1 and 2 combined.
