Student Attendance

Importance of Attendance in a Continuous Assessment System.

Please keep in mind that this is more of a blog and less of a scientific paper. To be honest, I just did not want all those real data to go to waste. 

In Nepal, academic session grade comes from end of the term final examination only. That is the way my parents got their grades, I got mine and my younger sibling got hers. However, things are thankfully changing now. Last year, we implemented Edcrayon in one of Kathmandu valleys' most reputed schools. The adoption allowed the school to easily transition from traditional end term assessment model to continuous assessment model. This implied that students would have to perform on a regular basis to get good grades. Unlike during my school days, mugging the entire course syllabus before the final exam would not help anymore. 

Similarly, most schools also had an allocated number of days for final exam review just before the exams. These review period entirely focused on the sort of materials that would be tested on the exam. Unfortunately, students were basically being prepared to pass the test. This also meant that even if students missed a significant number of school days, it would not really matter too much with their grades since they exactly knew what they had to prepare and mug up. Therefore, it is really difficult to identify the impact of attendance on grades in traditional grading system. 

However, with the introduction of Continuous Assessment System, since final grade is basically a summation or curation of student performance throughout the academic session, I wanted to study if student attendance had an impact on the final grade.

Is there a correlation between kindergartener's attendance rate vs final grades? Similarly, is there a correlation between a middle schooler's attendance rate vs final grades? I had access to real academic data for a school and wanted to enquire the relationship.

Null Hypothesis:
There is no relationship between attendance and final grades in continuos assessment model.

Class KG
Number of students: 11

Note that the sample size in this case is very very small. The number of students in Kindergarten level were only 11 in the school we worked with.

Class: 4 (Three sections)
Number of students: 104

In both cases, r is greater than 1 which implies positive correlation. Also, correlation is significant at 0.05 and 0.01 respectively. Therefore, we can reject the null hypothesis. 

Students benefit from being present in the class in continuous assessment system.

The Zorganian Republic has some very strange customs. Couples only wish to have female children as only females can inherit the family's wealth, so if they have a male child they keep having more children until they have a girl. If they have a girl, they stop having children. What is the ratio of girls to boys in Zorgania?
The ratio of girls to boys in Zorgania is 1:1. This might be a little counter-intuitive at first. Here are some ways of tackling this problem. 1. Monte Carlo Simulation: Although, Monte Carlo simulation does not necessarily show why the result is 1:1, it is appropriate because of the very counter-intuitive nature of the problem. At the very least, it helps us see that the result is indeed 1:1. Therefore, this is a good start.
The following R code estimates the probability of a child being a boy in Zorgania. 
couples <-100000 boycount <-0for (i in1:couples){ # 0: boywhile (sample(c(0,1),1) ==0) { boycount=boycount+1 } } probability <- boycount/(co…

Simple Launcher

A simple minimal launcher application for Android devices that shows battery percentage using lzyzsd's CirclProgress library (ArchProgress used in this case) and BroadcastReciever for battery state, Android's clock widgets, a built-in flash light switch and an app list view that can be toggled. Currently, the toggle simply filters all the app that I am working on at present. Future implementation can allow users to select their favorite apps or populate second toggle based on the most used applications.
