Hypothesis Testing To Compare CIM₁₅₂₄ Data For Apex, Base, And Lateral Surface Measurements

CIM Property		Frequency range (kHz) with p-value < 0.05
		Lateral-Apex	Apex-Base	Lateral-Base
With OR	R	20–100	1–100 - {50}	1–100
	X	9–400	1–400	1–600
	|Z|	20–400	1–200 - {50}	1–300
	Φ	20–500	1–500	2–500
Without OR	R	2–90 - {3,6}	1–90	2–500
	X	7–400 - {20}	1–400	1–400 - {20,40, 50}
	|Z|	20–400	1–90	1–200
	Φ	2–400 -{3,6,300}	1–900 - {600}	2–500

OR: Outlier Removal (data beyond 5^th and 95^th percentile was removed)

The numbers represent range of signal frequencies for which the null hypothesis that the two datasets had same population mean can be rejected at a significance level of 0.05 (p-value<0.05). A t-test was performed. The numbers in the brackets list the frequencies that are exception within the given range of signal frequencies.
