Abstract: An information processing device includes a statistical processing unit that performs statistical processing for a group of spectra obtained by applying light to a group of microparticles that exhibit one response property with respect to light, and on a basis of a result of the statistical processing, exclude a spectrum indicating an outlier from the group of spectra, and a reference spectrum calculation unit that calculates a reference spectrum using the group of spectra from which the spectrum indicating the outlier has been excluded.
