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).
The single-sample t-test compares the mean of the sample to a given number (which you supply). The independent samples t-test compares the difference in the means from the two groups to a given value (usually 0). In other words, it tests whether the difference in the means is 0.The dependent-sample or paired t-test compares the difference in the means from the two variables measured on the same set of subjects to a given number (usually 0), while taking into account the fact that the scores are not independent.est statistics. g. writing score-reading score-This is the value measured within each subject: the difference between the writing and reading scores. The paired t-test forms a single random sample of the paired difference. The mean of these values among all subjects is compared to 0 in a paired t-test.
