Median

> Example – evennumberofobservations >
 * ====== Can be used for ordinal and numerical variables, but not nominal variables ======
 * Used primary when we have categorical Ordinal variables
 * ====== Is the middle value when the observations are arranged in order of magnitude ======
 * ====== We need to rank the scores ======
 * We collect data – test scores from 11 students[[image:Picture3.png width="800" height="66"]]
 * We rearrange the test scores in ascending order

5 + 7 / 2 = 6 which is the median in this case
 * Then we he average of the two in the middle:

 * Informs about the point in distribution where that are 50% cases above and 50% below
 * An advantage, or disadvantage, is that it is unaffected by extreme values
