Please explain what the Pareto Chart tells regarding 80 percent and 20 percent means.
Based on the information and the pareto chart what would you work on based upon what the Pareto Chart is telling you?
This is the data to construct the Pareto chart and
The team has collected data for Everyday High School (EDS) and
the data reflects those things that affect student performance. You
need to know which of those factors is giving you the most trouble.
The Pareto Chart is a good tool for this. (The 80/20 rule)
Survey Question: What do you feel is the largest factor at
EHS that impacts student performance on the MEAP?
Responses from each of the six major customer groups
(# surveyed in parentheses) fell into 10 overall categories:
1 - the teacher the student had during the testing year
2 - the teaching style of the teacher
3 - the grade level of the student
4 - whether or not the student was in special education
5 - the socio-economic status of the family from which the student came
6 - whether or no the student was from a two parent home
7 - whether or not the student was involved in extra curricular activities
8 - the GPA of the student
9 - whether or not the student was involved in community activities outside of school
10 - student attendance

Pareto Chart and Frequency
Pareto analysis is a statistical technique in decision making that is used for selection of a limited number of tasks that produce significant overall effect. The chart shows that the most important factors related to students' performance are (in this order): Attendance, Teacher, Extra Curricular, Teacher Style, Community Involvement, and GPA. In other words, these factors are responsible for the 80% of students' performance.
