WebThe freqs vector contains the x-axis (frequency bins) and the psd vector contains the y-axis (power spectral density). The units of the power spectral density, when working with EEG data, is usually micro-Volts … Web19 feb. 2024 · For example, there were 20 items sold in the price range of $1 – $10. Thus, the relative frequency of the class $1 – $10 is 20 / 66 = 0.303. Next, there were 21 items sold in the price range of $11 – $20. Thus, the relative frequency of the class $11 – $20 is 21 / 66 = 0.318. We perform the same calculation for each class to get the ...
