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 many will make up about 20%.

CONTD… 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 complaints, and so on. Wilkinson (2006) devised an algorithm for producing statistically based acceptance limits (similar to confidence intervals) for each bar in the Pareto chart.

CONTD… There are two ways to analyze Pareto data depending

on what you want to know:

• Cost Pareto

• Count Pareto

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.

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.

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 for one of the major reason.
