a simple tool for calculate Relative Standard Deviation (RSD) , means ,Standard deviation etc.
Tool Principle
RSD calculation formula = STDEV.S()/AVERAGE()
SD standard deviation formula = STDEV.S()
SE standard error formula = STDEV.S()/(n-1)
Geomertic Mean formula = PRODUCT()^(1/n)
Usage Steps
1- input data in data cell or switched to test input area
Note:
a- cell input mode is best for mobile input mode, as it will triger digit key board, and you can add or redeuce cell easierly, which is easy and easy to understand
b- test area input mode might be used when you in PC or you want to copy and paste the original data direct, in case the original digit has been seperated by , or blank, it will be more efficient
2-once calculate button is clicked, all result will be displaied under calculation result
3-click SAVE icon if you want to review afterward, click copy icon for each line, the result is in you clipboard
4-click history you can see all saved item. Pls be noticed all data saved are still in you local broswer localstorage, will be availiabel in recent session. but not for permerant storage purpose
