Find (N) /2, (N is the total frequency) in the cumulative frequency column and determine the median class. Apply the following formula to find the value of median. Median = L +( N/2 – C.f) / f x i. In the above formula L = lower limit of the median class. N = total frequency. Cf = cumulative frequency of the class above the median class

https://info.5y1.org/formula-for-cumulative-frequency_1_4de3fb.html
Power Spectral Densfty (PSD) is the frequency response of a random or periodic signal. It tells us where the average power is distributed as a function of frequency. ( The PSD is deterministic, and for certain types of random signals is independent of time1. This is useful because the Fourier transform of a random time signal is itself random ...
