      Remember that correlation measures the direction and the strength of the relationship. Dividing both variables by 12 will not change the direction or the strength.

      There does not appear to be consensus in the literature about exact correlation values to determine whether reliability is excellent or adequate as there are many factors that impact on these scores. According to Rosaroso (2015) “As a rule of thumb, reliability coefficients of 0.8 or above are within acceptable standards” (Rosaroso 2015 p371).

      If there is no serial correlation, the DW statistic will be around 2. The DW statistic will fall if there is positive serial correlation (in worst case, it will be near zero). If there is a negative correlation, thestatistic will lie somewhere between 2 and 4. Usually the limit for non-serial correlation is considered to be DW is from 1.8 to 2.2.
