An ogive (oh-jive), sometimes called a cumulative frequency polygon, is a type of frequency polygon that shows cumulative frequencies.In other words, the cumulative percents are added on the graph from left to right. The points plotted are the upper class limit and the corresponding cumulative frequency. (2) 3, pp. 2. The points plotted on the graph represent the total accumulated frequencies associated with each T‐value. The Ogive for the normal distribution resembles one side of an Arabesque or Ogival arch. Interpret the meaning of this point in context. Difference between ‘less than’ and ‘more than’ ogives: Less than Ogive More than Ogive 1.
