Number of Data Sets per Pitch (3 tests by battery) x 6 = 18

Test Data Overview

Data Set Analysis: For each test, the average (mean) and standard deviation (STD) of RGB values were calculated to determine central tendencies and variation in the data.

Distance Calculations: Relative Distances- Calculated as the absolute difference between the current and previous RGB values, normalized by 255 to express the difference as a percentage.

Z-Score Calculation: Z-scores were used to measure how far each RGB value deviates from the average, helping to identify outliers.

Normalized Distribution: Each RGB value was normalized to a scale between 0 and 1 using the minimum and maximum values of the dataset.

Closeness to Target Color (Euclidean Distance) Calculated to measure the distance between each test result and the corrected average (target color). If the distance was less than 30%, the result was classified as “Close”; otherwise, it was classified as “Off.”

Geometric Distance Results

Pass/Fail Classification: Texsyn Toolbox Method-Tests are evaluated based on Euclidean distances. If the total distance is less than 1, the test is classified as “Pass,” and if greater than 1, the test is classified as “Fail.” This method aligns with the Synesthesia Battery / Texsyn Toolbox. https://synesthete.ircn.jp/files/EaglemanetalSynesthesiaBattery2006.pdf

Average RGB Without Outliers (Z-score < abs(2))

Recalculation Excluding Outliers: After identifying outliers, averages, minimums, and maximums were recalculated to define a more accurate target color by excluding extreme values.

Statistic	R	G	B	Color Name
Average	67	171	136	BLUE-GREEN

Average RGB of Outliers Only (Z-score > abs(2))

Outlier Identification and Trend Analysis: Outliers are analyzed separately to explore possible patterns or relationships between pitch proximity and color, considering color blindness and relative pitch shifts.
