PARETO DIAGRAM (BUNKING LECTURES)

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.

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

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!

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!

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!).

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!

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?

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?!

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!

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

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.

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 :)

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.
