4. What is a pareto diagram ?
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.
Because the reasons are in decreasing order, the
cumulative function is a concave function. To take the
example above, in order to lower the amount of late
arrivals by 78%, it is sufficient to solve the first three
issues.
5. This diagram shows the pareto chart of titanium investment
casting defects. The left vertical axis is the frequency of
occurrence, but it can alternatively represent cost or another
important unit of measure.
The right vertical axis is the cumulative percentage of the total
number of occurrences, total cost, or total of the particular unit of
measure.
6. 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.
These charts can be generated by simple spread
sheet programs, such as OpenOffice.org
Calc and Microsoft Excel [1] and specialized statistical
software tools as well as online quality charts
8. Is your child bunking lectures ?
Often when children pass into their preteen years, they
discover the fun of bunking lectures. It may start out by
accidentally missing one lecture, but it soon snowballs
into something much worse. Soon they will have missed a
lot of important lectures and then they end up performing
poorly in exams.
9. Number of
students
year
With the help of this graph we can easily identify that the
students are missing their lectures year by year more of.2010
there were 10 number of students missing their lectures and
so in 2011 there were 20, in 2012 there were 30,in 2013 there
were 35 and in 2014 there were 40. we can notice that the
number of students bunking the classes are been increased.

10. Therefore, the symptoms for not attending the lectures can be :
Negative remarks from the
teacher.
Incomplete assignment or
any project.
being lazy, unfocussed and
less ambitious.
Lack of personal interest in
studies.
facing a genuine problem at
school, problems like getting
teased by his mates or say he
may be getting bullied.
Available opportunities for
entertainment like malls,
movie halls etc.
a particular teacher keeps
picking on them.
Inability to keep up with the
subject.
indulge in some other
activity that he cannot find
time for otherwise.
peer pressure.ie. to hang
out with peers.
His mates often mass
bunk and your child may be
doing the same to fit in.
The mental capacity of a
students does not matches
with the course opted.etc.
12. Identification of Symptoms which are mostly possible :
Some of the factors which are mostly been observed in the
students are :
Lack of personal interest in studies.
facing a genuine problem at school, problems like getting
teased by his mates or say he may be getting bullied.
Available opportunities for entertainment like malls, movie
halls etc.
a particular teacher keeps picking on them.
His mates often mass bunk and your child may be doing the
same to fit in.
The poor teaching skills of a teacher also keep away student
from the school.
13. Graph 1.2
With the help of this diagram we can easily identify that the 80%
of the frequency symptoms can be the poor teaching skills of the
teacher.

14. Relative Importance of Factors Used to Decide on Lecture
Attendance(graph 1.3)
The figure lists various factors from the highest mean
importance score to the lowest (based on a five-point scale in
which 1 was “not at all important” and 5 was “extremely
important.
16. Problem definitions :
There are some major problems which can take place when
the students are bunking lectures. These problems are :
Problem of not in touch : the child may face the problem of
not getting in touch with the subjects. He may loose his
internal credits. Though he may be easily identified within
the teachers, school staffs or may be the peers as a truant .
Not controlled early :another drawback can be that if the
bunking of the student is not controlled early, he may end up
bunking a LOT more lectures in junior and senior college
which can make the child lazy, unfocussed and less
ambitious which may also indicate that he is not taking
17. Dynamic teaching-learning environment :The absenteeism
disturbs the dynamic teaching learning environment and
adversely affects the overall well being of classes.
Wastage : Bunking lectures may do the wastage of
educational resources, time and human potential and also
causes rework and wastage time of lectures.
Valuable information : when students are absent from the
class they miss a lot of valuable information which results
from peer-lecturer interaction and the benefits of the specific
examples lecturers use to clarify difficult concepts.
Future destruction : bunking the lectures can spoil the future
of the student .They will not be able to learn the actual
means of discipline and other moral values which is taught
in the classroom.
18. This picture shows that the child is running from the classroom
and so because of that one child the whole classroom discipline
and even the concentration of the teacher is been disturbed.
20. Lesson learned by the team :
Student absenteeism is a serious issue in public
education. Concerted efforts have been expended aimed
at engaging students and promoting active learning,
but schools/colleges are still full of “clock watchers”.
Many students regularly skip lectures and student
absenteeism is a major concern for lecturers at institutions of
higher learning. Absences create a dead, tiresome, unpleasant
classroom environment that make students who come to class
uncomfortable and the lecturer irritable .
