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).
We can also use either Excelâs t-Test: Paired Two Sample for Means data analysis tool or the T Test and Non-parametric Equivalents supplemental data analysis tool to get the same result. The output from the Excel data analysis tool is shown in Figure 4.e summarize the results from the two analyses as follows: Figure 7 â Comparison of paired and independent sample t tests. Note that the mean differences are the same, but the standard deviation for the paired sample case is lower, which results in a higher t-stat and a lower p-value.
