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).
Paired t-test. This tutorial will walk you through the use of the paired t-test. The paired t-test should be used when the data are in pairs. One of the most common uses of this test is a before- and after- (pre and post) analysis. For example, we might be interested in how much a certain group grows after fertilizer is added to randomly selected plots.
