Answer to Question #209432 in Math for Harsh Kumar

Question

If the error function for 4 experimental points equals to 50.4, then the root mean square (rms) for these points equals to

Answer 1

Solution:

Given, Error function, $E=50.4$

And number of observations, $N=4$

Then, $RMS=\sqrt{\dfrac{E^2}{N}}=\sqrt{\dfrac{50.4^2}{4}}=25.2$
