There is a column B4:B8 containing a population of data. To get the standard deviation, please use formula as below: =STDEV.P(B4:B8) Or you can directly type the data as an array in the formula =STDEV.P({10,22,30,41,37}) ...
The term RAID stands for an independent set of inexpensive disks and dates back to when large hard disks were very expensive. At that time, it was very profitable to assemble one common array from several smaller disks. To date, the concept of this device has remained the same, but the ...
