2. INTRODUCTION
A Pareto chart, named after Vilfredo Pareto, is a type of chart that
contains both bars and a line graph, where individual values are
represented in descending order by bars, and the cumulative total is
represented by the line.
Vilfredo Pareto conducted a study in Europe in the early 1900s on
wealth and poverty. He found that wealth was concentrated in the
hands of the few and poverty in the hands of the many. The principle
is based on the unequal distribution of things in the universe. It is
the law of the "significant few versus the trivial many." The significant
few things will generally make up 80% of the whole, while the trivial

Pareto charts provide a tool for visualizing the Pareto principle, which
states that a small subset of problems tend to occur much more
frequently than the remaining problems. In Japanese industry, the
Pareto chart is one of the “seven basic QC tools” heavily used by
workers and engineers. Ishikawa (1976) discusses how to construct
and interpret a Pareto diagram. Examples of Pareto diagrams are also
given by Kume(1985) and Wadsworth and others (1986).
The purpose of the Pareto chart is to highlight the most important
among a (typically large) set of factors. In quality control, it often
represents the most common sources of defects, the highest
occurring type of defect, or the most frequent reasons for customer

There are two ways to analyze Pareto data depending
on what you want to know:
• Cost Pareto
• Count Pareto
5. BUNKING LECTURES
The topic chosen by our team: “Bunking Lectures”
We conducted a survey over 1500 students of our university. The
accounted reasons were as follows:
• Overslept
• No quality learning in the class
• Other assignments
• Non-interactive sessions
• Hangout with friends
A Pareto diagram was drawn out of the data collected through the
survey.

9. Problem Definitions
On the basis of symptoms that account for 80% of the
problem:
Students bunk lectures when they find them
unimportant and non-profitable in any case. A Boring
and one way conversation during the lecture is next to
wastage of time.
Bunking lecture, hence, is always not considered a
wrong and unjust to the education type of thing. It is a
major problem that could be sorted out by finding a
solution by pondering on the reasons for the problem.
10. Lessons learnt by the
team A major problem seen in the college going student is
’Bunking Lectures’.
On the basis of the survey we conducted in our University,
students seek for an interactive session in lectures. A way
they can well communicate with their ideas and their
respective execution in practical world. A one way traffic is
not so interesting in 99% cases.
Quality learning is important part of any kind of education. A
lecture has to be good in quality in terms of knowledge
gained. It makes learning attractive.
There are several assignments to complete which may not be
related to the lectures to be attended. Noticeable number of
students bunk their lectures for this reason and it accounts
