2. Cumulative Frequency Table
■ In a Frequency Table you keep count of the Number
of Times a Data Item occurs by keeping a Tally. The
Number of times the item occurs is called the
Frequency of that Item.
■ In a Frequency Table you can also find a ‘Running
Total’ of Frequencies. This is called the Cumulative
Frequency. It is useful to know the Running Total of
the Frequencies as this tells you the Total Number of
data items at different stages in the Data Set.

4. OGIVE CURVE:
■ The Ogive is a Cumulative Frequency Curve.
■ It is a Free-Hand Graph showing the curve of a
Cumulative Frequency.
■ The Ogive is Constructed by plotting the Upper class
limit on the X-axis and the Corresponding
Cumulative Frequency on the Y-axis.
■ Ogive is best used when the total Frequency at any
given time is to be displayed.

5. LESS THAN OGIVE:
■ Less than Ogive is the Graph of the Less than Cumulative Frequency
Distribution which shows the Number of Observation LESS THAN the
Upper Class Limit.
■ First we Calculate the Cumulative Frequency from the above (as Usual)
■ The Plot the Upper Class limit of Class Interval against the value of
Corresponding Cumulative Frequency.
■ The Points are joined by a Free-Hand Smooth Curve.
■ The Lower Point of the Curve is joined to the X-axis at the Lower Limit
of the First Class Interval.

8. GREATER THAN OGIVE
■ Greater than Ogive is the Graph of the Greater than
Cumulative Frequency Distribution which shows the Number
of Observations GREATER THAN the Lower Class Limit.
■ First, the Frequencies are Cumulated from Below.
■ Then the Cumulated Frequency is Plotted against the Lower
Limit of the Corresponding Class Interval.
■ The Upper Most Point is joint with the Y-axis at the Upper
Limit of the Last Class.
