A measurement apparatus is equipped with a processor. The processor acquires first velocity data, which is data on a velocity in a first direction, and second velocity data, which is data on a velocity in a second direction orthogonal to the first direction, on the basis of accelerations acquired at an acceleration sensor. The processor calculates a first coefficient on the basis of the acquired first velocity data and the acquired second velocity data. The processor determines whether the measurement apparatus is installed in normal orientation on the basis of the calculated first coefficient.
