An analytical method has been developed for determining the true value of the central tendency of each of annual maximum and annual minimum of ambient air temperature at a location. Also, the value of central tendency of each of annual maximum and annual minimum of ambient air temperature at Dhubri has been determined by applying the method developed here from the data since the year 1969 onwards. Determination of these two values is based on the assumption that change in temperature over years during the period for which data are available occurs due to change cause only but not due to any assignable cause. The values of these two have been found to be 37.1 and 37.2 Degree Celsius and 8.8 Degree Celsius respectively. Moreover, it has been found that the central tendency of annual minimum of the ambient air temperature at Dhubri cannot be less than 8.7409 Degree Celsius and greater than 8.75 Degree Celsius.
