Graphical Representation of Quantitative Data

Q. What Is Data Analysis With Example

Q. The following table gives the distribution of IQs (intelligence quotients) of 60 pupils of class V in a school:

IQs:	125.5 to 13.25	118.5 to 125.5	111.5 to 118.5	104.5 to 111.5	97.5 to 104.5	90.5 to 97.5	83.5 to 90.5	76.5 to 83.5	69.5 to 76.5	62.5 to 69.5
No. of pupils:	1	3	4	6	10	12	15	5	3	1

Draw a frequency polygon for the above data.

Q. representation of data helps us to understand the data more easily than a table.

1. Tabulated
2. Graphical
3. Unorganised
