PURPOSE:To achieve a higher accuracy of an end point method, by a method wherein an object to be measured is made to react with a reaction reagent to preset a time range in which the object being measured gives stable reaction data and a statistic processing is performed about a plurality of data obtained within the time range. CONSTITUTION:Curves 1 and 3 indicate actually measured data. When the data between the points M and N is outside an allowable error range epsilon due to bubbles and foreign matters attached at a portion following a point P the data between the points P and N is corrected to obtain a correction data as shown by a curve 2. The data between the points M and N is outside the allowable error epsilon only at a point Q, the data only at this one point is corrected to obtain a correction data as shown by a curve 4. In this manner, a measured data is corrected when considered as subjected to a long-term disturbance such as caused under the influence of bubbles in the range previously specified by M and N. Then, an approximate straight line is determined by the least square method to obtain the most probable value at the final point N as specified from the approximate straight line thus obtained.
