EEG Power Analysis Data from Holographic Display Study in Museums

This dataset contains the spectral power values derived from EEG recordings collected during the experiment. It includes cleaned data from 24 participants across three display conditions (hologram, photograph, and 3D-printed model). Outliers were manually identified and removed using a ±3 standard deviation threshold to ensure the accuracy of the results. The dataset was used for the statistical comparisons reported in the manuscript.
