2. Pareto chart
 It shows the relative importance of set of
measures
 Helps to select the most important areas on
which to focus
 It helps us to differentiate between vital few and
trivial many
 It is also called as 80-20 rule, which states that
20% of potential problem areas are caused by
80% of all the problems

3. Bunking of lectures
 Following are some reasons to bunk the lectures
1. Quality and clarity of lectures
2. Deadline for other activities
3. Lecturers ability to engage/entertain
4. Availability of lecture material from printed
sources
5. Hour at which class is scheduled
6. Need to attend Extracurricular or personal
activities
7. Lack of sleep
8. Locations around college and peer reasons
(theatres, picnic spots, restaurants etc.)

4. Data
 Survey was conducted on 150 students to rate
the reasons mentioned in slide
 Location of college : Churchgate
 Places around : Marine Drive, theatres, Gateway
of India, Colaba, Restaurants and clubs
 Schedule : 12 Hrs a day, 6 days a week
 All other parameters are subjective to students

Plot the bar graph accordingly.
We also need cumulative frequency to plot the line graph

Reasons for bunking lecture

10. Conclusion
 As you can see 72% of the problems are caused
by the 2 factors which make 25% of the reasons
 Here 80/20 principle is being followed but due to
small amount of data set has little variation
 If the quality of lectures are improved the problem
can be tackled to a large extent as perception
must be created among student that their time is
more useful in lecture than to visit outdoor places
which they can visit later
