You will need endpoints of your range (for example age: 12-14, 15-17. The endpoints are 14 and 17).
You will also need the cumulative total of the relative frequencies (add all relative frequencies).
-To find the relative frequency = value over total (ex, age 12-14, 51 have Diabetes, 90 do not. The total of those having diabetes is 3800. So for the relative frequency of ages 12-14, it is 51/3800=0.01342. Do this for all ranges).
-To find the Cumulative Frequency: add all these frequencies (separate for "yes" diabetes and "no" diabetes).
Use endpoints of your range for the x-axis (horizontal axis). Then use the cumulative frequencies as your y-axis (vertical axis).

What are interpolation of ogive curve?
An ogive is a cumulative relative frequency diagram. Interpolation is definiting the midpoint (50%) of this line
The graph of a cumulative frequency distribution is called?
ogive
Usefullness of ogive curve?
In statistics, the ogive curve is an approximation to the cumulative distribution function. It can be used to obtain various percentiles quickly as well as to derive the probability density function.
What is another name for cumulative frequency polygon?
It is called an ogive.
What are advantage of ogive?
Original information from grouped data can be obtained
What is an ogive curve?
Ogive is an free hand uprising curve
How you CAN draw an 'ogive'?
First, get a pencil, some paper and a stencil of an Ogive. Then you fill in the stencil. Job done
Is an ogive a graph of cumulative frequency distribution?
yes. An ogive is also known as a cumulative frequency graph.
What are interpolation of ogive curve?
An ogive is a cumulative relative frequency diagram. Interpolation is definiting the midpoint (50%) of this line
What is the difference between an ogive and a frequency polygon?
The ogive never close because they represent non-decreasing functions, and polygon you close it.
What does the point of intersection of less than ogive and more than ogive correspond to?
the intersection of less and more than ogive gives us the median of the following data.. but the median is not accurate as we draw the free hand cumulative graph..
What is represented on the y axis to draw an ogive?
The y-axis of an ogive is always the cumulative frequencies while the x-axis is the class boundaries.
What is another name for a cumulative frequency polygon?
Ogive
Another name for cumulative frequency polygon?
OGIVE
