Document Summary
Median - the goal of the median is to locate the midpoint of the distribution. No specific symbols or notation to identify the median. Definition and computations for the median are identical for a sample and for a population. If the scores in a distribution are listed in order from smallest to largers, the median is the midpoint on the list. The median is the point on the measurement scale below which 50% of the scores in the distribution are located. Defining the median as the midpoint of a distribution means that the scores are being divided into two equal-sized groups. With a continuous variable, it is possible to divide a distribution precisely in half so that exactly. 50% of the distribution is located below a specific point. Finding the precise median for a continuous variable. Continuous variable - consists of categories that can be split into an infinite number of fractional parts (eg. time)
