The present invention ensures the reliability of measurement information about a cell measured by mobile terminals and enables the measurement information to be utilized for the optimization of a mobile communication network. An analysis device acquires measurement information about a reception signal state measured by a measuring instrument, acquires, together with terminal type information, measurement information about a reception signal state measured by mobile terminals, statistically processes the measurement information of the measuring instrument and the measurement information of the mobile terminals for each terminal type to generate respective typical data, groups similar pieces of the typical data of the measuring instrument and the typical data of the mobile terminals for each terminal type into the same group, and generates a measurement representative value distribution on the basis of the distribution of the typical data included in the same group and the distribution of terminal types in the group.
