The arithmeticmidpoint is used here for simplicity. The median is defined as the diameter for which one-half the total number of particles are smaller and one-half are larger. 5. The modeis the most frequentsize, or the diameter associatedwith the highest point on the frequency function curve. setting the derivative of the frequencyfunction equal to zero and solving for d. For symmetricaldistributions such as the normal distribution, the mean,median,and mode will have the samevalue, which is the diameter of the axis of symmetry.
