To average response times by month, you can use a formula based on the AVERAGEIFS function, together with the EOMONTH function. This formula uses the named ranges « dates » (B5:B25) and « durations » (D5:D25). Durations column D are in minutes, calculated by subtracting the date opened from date closed.
What is the formula used to calculate turn around time? After 2 seconds, the CPU will be given to P2 and P2 will execute its task. So, the turnaround time will be 2+5 = 7 seconds. Similarly, the turnaround time for P3 will be 17 seconds because the waiting time of P3 is 2+5 = 7 seconds and the burst time of P3 is 10 seconds.
Similarly, How do I calculate the tat between two times in Excel? Another simple technique to calculate the duration between two times in Excel is using the TEXT function:
- Calculate hours between two times: =TEXT(B2-A2, « h »)
- Return hours and minutes between 2 times: =TEXT(B2-A2, « h:mm »)
- Return hours, minutes and seconds between 2 times: =TEXT(B2-A2, « h:mm:ss »)

How do you combine averages and standard deviations?
The Standard Error of the mean is calculated as SE = SD / sqrt(n) of each group. After combining them using the Random Effect Model, the Standard Deviation can be recalculated as SD = SE * sqrt(tn) , where tn is the sum of sample sizes from all the groups.
…
- tn = sum of all (n)
- tx = sum of all Σx.
- txx = sum of all Σx 2
How do you find the combined standard deviation of two samples? Namely, after we square the SDs, we divide each by its own sample size. Then add square root to get the combined standard deviation.
