The presentation by students from Daffodil International University outlines the concept and importance of graphs, detailing their structure, types, and uses in various fields including academia and corporate settings. Graphs are highlighted as essential tools for organizing and interpreting data, facilitating comparisons, and demonstrating relationships between variables. Additionally, real-life applications, such as medical graphs used for patient assessments, are discussed.

4. What is Graph
 A graph means that relation between two
variable quantities, typically of two
variables and measured at right angle in a
diagram.

5. Basic Graph
 In graph we have ‘X’ and ‘y ’ axis and x-prime
and y-prime axis. There has 4 quartile in a graph.
Those called 1st quartile, 2nd quartile, 3rd quartile
and 4th quartile.

6. Basic kinds of Graph
A scatter graph.
A line graph.
A bar graph.
A pie graph/diagram.

11. Why do we use graph
1.Its an organized way to express data.
2.Allows for easy interpretation of the
data.
3.They make it easier to comparisons.
4.They make it easier to changes.
5.Thay organize data.
6.Show math relationship.
7.See relationship between variables.

12. Importance of graph
Graphs are beneficial because they summarize
and display information in a manner that is easy
for most people to comprehend. Graphs are used in
many academic disciplines, including math, hard
sciences and social sciences. They make appearances
in corporate settings, serving as useful tools to
convey financial information and facilitate data
analysis.

13. Graph Used in real life
• Medical graphs are used to collect
information about patients, such
as graphs showing a 1 to 10 pain
scale for patients after surgery.
These charts can help doctors and
nurses quickly assess the
effectiveness of pain medications
and help doctors determine when
to adjust medications as needed
for a patient's comfort.

14. Used for count average population
In Bangladesh There has a system to count
population. This system is called census. By
this system population is count 10 years
after 10 years.
