The document discusses reasons why students bunk or miss lectures and analyzes them using a Pareto diagram. It lists 10 common reasons for bunking lectures and their frequencies. A Pareto diagram shows that the top 5 reasons - festive time, peer pressure, relatives visiting, love interests, and friendships - account for 80% of bunking instances. Each of the top reasons is then discussed in more detail explaining why students often use that reason to bunk lectures. The document concludes by listing lessons learned by creating the Pareto diagram analysis.

3. Pareto chart
A Pareto chart, named after Vilredo 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.
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. 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.
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.

7. Reasons that account for 80% frequency
1) Festive time
2) Peer pressure
3) Relatives are coming
4) Love
5) Friendship doesn't happen in classroom

8. OVERSLEPT!
On maximum number of occasions,
this is the primary reason behind why
people miss/bunk classes. Staying up
late at night for talking to your loved
one, playing multiplayer games or
even watching a movie, it is inevitable
that you will be unable to wake up the
following morning to attend your
lectures. And even if you are able to
(the remotest of cases) you’ll be the
personalization of Snorlax, the
Pokemon!

9. Love doesn't blossom between
closed walls
One of the last things you would want
to do is get on your boyfriend or
girlfriend’s nerves! The wrath of the
better-half is like the wrath of few
others! If he/she has asked you to be
there at place X at time Y, you better
make sure you reach at time Y-1! On a
serious note, spending some quality
time with that one person you love can
serve as a very good reason for you to
miss classes. Even if you don’t have a
girlfriend/boyfriend, if your crush asks
you to meet you know yourself that
you’re going to leave no stones
unturned in making sure that happens,
irrespective of external factors!

10. FESTIVAL TIME
This often entails what is commonly
known as a ‘mass bunk’- where the
entire student community is gripped by
the motivation to bunk the remainder
of the classes in order to enjoy the
upcoming festival (eg, Durga Puja,
Ganesh Chaturthi, Dusshera, etc). In
most cases the decision is
communicated to the teachers and
they, without having any other option,
comply! But in many cases, the bunk
simply happens ‘underground’. One
fine day when the teacher visits the
class, all he finds are benches and
desks staring back (almost
sarcastically!).

11. FUN WITH FRIENDS
This is more common in colleges
where there is no one on campus to
take you by the collar and put you right
back in class (we had such people in
our school!!). Be it the college canteen,
the basketball court or football ground,
the table-tennis board or even the
common room where the TV is, fun is
where friends are! And it seldom
remains restricted to that; bunking a
class with friends often entails going
out for movies, or going to the nearest
restaurant, pub, cafe, etc. And even
when you run out of options, bunking
the class you’re meant to be in and
visiting other classes just for the fun of
it…yep, that is a different kind of fun
altogether!

12. Professors Bore me to Death
Sometimes you don’t really need a
reason. The teachers or professors
with their God-awful, monotonous way
of teaching will give you one. Their
lectures can get so deplorably
uninteresting that you might be visited
by sudden urges to literally run out of
the class (with bleeding ears!!). Their
threats, their warnings all seem to take
a backseat as you run to take cover
and preserve your sanity! No, even
sleeping in their class doesn’t help-
how can it when Sleep itself is scared
to visit the four walls in which someone
so mundane is present?

13. PEER PRESSURE
Have you ever bunked a class?”,
“No…not really”, “Dude!!! Are you the
teacher’s pet or something? So not
cool man!”…. And thus you come
under the scanner of your ‘cool’
buddies and an insuppressible urge to
impress them overcomes you!
Naturally, no one feels good to be left
out, much less be ostracized from the
‘cool group’ in school or college and
thus, bunk you must! If they are
bunking classes, so must you. If they
are not taking notes, neither should
you. If they are sleeping in the back
benches…erm…are you daring
enough to do that?!

14. RELATIVES ARE COMING
Another overused trick to draw the
blinds on your actual intentions. Family
is always important right? And when
you turn it into an excuse, teachers are
left defenseless. They don’t want to be
the ones to restrict you from meeting
your near and dear ones! They’ve got
families too! And in any case, said in a
convincing manner – eg, my uncle is
coming all the way from blah-blah and
he comes here just once every
year…last year he was unable to come
because of blah blah…so please
excuse me for a day or two, sir- there
is absolutely nothing your teacher will
be able to say to keep you!

15. NOTES ZINDABAD
As the Gen-y students we
need to be advanced in every
aspect of life and adopt the
new technology .So why not
adopt the latest revolution that
is Lecture slides ? There are
some class room notes that
need to be photocopied, for
everything else there are
lecture slides. My college
being one of the premier
institutes in the country there
is no dearth for lecture slides
at all. There are even
advanced versions made
using the imaginary flow chart
given below

16. I already know it all
Having got admission into the college
via the prestigious entrance test, we
already know a lot. Much of the
curriculum in the early days is
already known to us during our
preparation for the entrance and hence
we need not attend the classes.
Moreover, as intelligent as we are , we
know lot of stuff that was learnt during
our pursuit of topics of personal
interest.

17. Friendships don't happen in Classrooms
Everyone knows that you can't have
fun in a classroom. And, you also know
that friendships are formed during fun
time. So, if I don't want to remain alone
through my college life, then I have to
go out and make friends. I need to go
for fun trips, watch some random
worthless movies and play games that
are designed for kids. After all, friends
are the ones who are going to help you
in preparing for exams :)

18. Lessons learned by the team
1)Every challenge gives us the zeal to work hard.
2)This challenge helped us to know various reasons for which
the students bunk the classes .
3)We came to know how pareto is made and what exactly is
the concept of pareto.
4)We also compared the reasons and the frequency using the
pareto diagram.
