The boxplot below is based on the birth weights of infants with severe idiopathic respiratory distress syndrome (SIRDS). Step 1: Calculate the measure of center/variation for each set of data. There are three important measures of central tendency commonly used to summarize a set of data: mean, median, and mode. The mean is the average of the data, the median is the center value, and the mode is the value that occurs most often. While quartiles are not a 1-number summary of variation like standard deviation, the quartiles are used with the median, minimum, and maximum values to form a 5-number summary of the data. One solid method to help you establish the identity of what the information is telling you is to locate the center of of the statistics itself.
