Burn Rate Formula. An alternative method of calculating the rate is to estimate the cash flow over a given period of months and then divide by the number of months. Cash burn rate = Cash flow from operating and investing activities / Number of months. In the formula the cash flows referred to are defined as follows.
The paired t-test, also referred to as the paired-samples t-test or dependent t-test, is used to determine whether the mean of a dependent variable (e.g., weight, anxiety level, salary, reaction time, etc.) is the same in two related groups (e.g., two groups of participants that are measured at two different time points or who undergo two different conditions).
Pair-difference t test (a.k.a. t-test for dependent groups, correlated t test) df= n (number of pairs) -1 This is concerned with the difference between the average scores of a single sample of individuals who are assessed at two different times (such as before treatment and after treatment).
