Cumulative frequency curve or an ogive is the graphical representation of a cumulative frequency distribution. We can construct an ogive by using More Than Method
More Than Method : - Following are the steps for constructing an ogive.
(a) Construct a more than type frequency distribution table.
(b) Mark the lower class limit on X- axis
(c) Mark the corresponding cumulative frequency on Y-axis.
(d) Plot the points and join them by smooth free hand curve.
The obtained curve is thew More Than Type Ogive.
Illustration : The frequency distribution of scores obtained by 230 candidates in a medical entrance test is as follows :
| Scores | 400-450 | 450-500 | 500-550 | 550-600 | 600-650 | 650-700 | 700-750 | 750-800 |
|---|---|---|---|---|---|---|---|---|
| No. of Candidate | 20 | 35 | 40 | 32 | 24 | 27 | 18 | 34 |
Draw cumulative frequency curve or ogive by more than method.
Solution : - First convert the given frequency distribution table to More Than Type frequency distribution table.
| Scores | No. of Candidates |
|---|---|
| More than or equal to 400 | 230 |
| More than or equal to 450 | 230-20=210 |
| More than or equal to 500 | 210-35=175 |
| More than or equal to 550 | 175-40=135 |
| More than or equal to 600 | 135-32=103 |
| More than or equal to 650 | 103-24=79 |
| More than or equal to 700 | 79-27=52 |
| More than or equal to 750 | 52-18=34 |
Now mark the lower limits along X-axis and cumulative frequency along Y-axis, and plot the points (400,230), (450,210), (500,175), (550,135), (600,103), (650,79), (700,52), (750,34).
Join the points listed above by smooth free hand curve to obtain the more than type ogive.

My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.

Being a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.

It was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.

One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.

It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.

Abhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.

Abhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.

It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice

My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.

I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
