Unlike all other exam result analysis that i have done on this blog, this time I gave myself the challenge to use just two charts to analyze the June 2010 exam results.
[This is fairly a long post and if you are not an AeSI student, you can skip the post!']
My aim was to capture all the info and insight in just two charts!
I have selected a box plot and a stacked column chart to capture the information!!
The Box Plot
Click the diagram to see better.
Boxplot shows the spread of the marks and the stacked column chart shows the count of passing students!!
In the above diagram, it shows what is the mark spread of each subject in section A!!
As you can see strength of materials had the highest marks in all subjects followed closely by applied mathematics 1!!
The yellow triangle indicates the median of all marks students got.
If we lined up all the students who passed engineering thermodynamics in terms of the mark in ascending order and asked the one in the middle what is his marks, this is what 58 indicates for ET in the chart.
Median represents the middle of the marks!!
This plot reveals that SOM, AM1, EDD, ET, and FM are real high scoring subjects and one can aim to get 80+ marks in each of them.
And the subjects EE, WT, MSE, and IA are the low scoring subjects. They had medians below 53!! This means most of the students just barely passed!!
The length of the box represents the variations in the marks, the higher the box, the larger the spread of the marks in those subjects. As expected with high marks, ET and SOM had the highest spread of marks ranging between 50 to 65!!
It's interesting to note that the lowest maximum marks was above 65!!
The stacked column chart.
This represents the frequency of marks obtained by students in each subject.
The blue colour indicates number of students who obtained marks between 50 and 60, orange represents the marks obtained between 60 and 70, orange represents the count of students who obtained marks between 70 to 80 and read represents number of students who obtained marks between 80 to 90.
As you can see, In EE, electrical engineering 90% of the students came under 60 and 10 % got between 60 t0 70!!
MSE was the subject which has close to 94% of students getting less than 60!!
SOM, FM were the two subjects in which 8 and 3 students respectively got more than 80%
SOM,ET,EDD,FM were the subjects that some students got marks between 70 to 80.
Numbers on the bars represent the number of students falling under the band of the colour.
Sum the numbers in each band and you have the number of students passing the exam for that particular subjects.
As you can see, except for ET and then SOM, the blue band of students is highest.
You aim should be to get out of this band. You aim should be to get into the red band..
So what does this all mean!!
These plots give you hard facts, facts to arm you to set your own targets for these subjects. They give you the insight to let you decide on how to study for each subjects. These graphs reveal the trend that you can use to your advantage while studying.
Would love to hear what you think of this? Please send in your comments!!
In next Post, I will post similar charts for Section B, so stay tuned.
