SpletThe median is the value separating the higher half of the data from the lower half. It is the determined particle size from which half of the particles are smaller and half are larger. This is also called D 50 (see Figure 1). The median is easy to determine from the cumulative distribution curve (s. Figure 4). SpletA normal distribution has some interesting properties: it has a bell shape, the mean and median are equal, and 68% of the data falls within 1 standard deviation.
