|Spectral Plot of 200 Normal Random Numbers|
We can make the following conclusions from the above plot.
|Discussion||For random data, the spectral plot should show no dominant peaks or distinct pattern in the spectrum. For the sample plot above, there are no clearly dominant peaks and the peaks seem to fluctuate at random. This type of appearance of the spectral plot indicates that there are no significant cyclic patterns in the data.|
