Impact of Part-Time Work on Student Performance

Introduction
The performance of students in higher education institutions is affected by various
factors. A Subject Coordinator at MMP is concerned about the performance of his student
over the past seven years. He obtains the data which contains various information about
students enrolled in particular subjects. The aim for this paper is to the data and help the
Subject Coordinator understand whether engagement in part time work really affects the
performance of his students.
The first task was to use implement two different sampling methods to obtain
samples within the same data set. The first sample of 25 students, Sample 1, was selected
randomly from the original data with 200 students. The Data Analysis Toolpak in Microsoft
Excel was used to identify the using the randomized technique. The second sample of 25
students, Sample 2, was systematically selected using Microsoft Excel Data analysis Toolpak,
where we selected the periodic technique so that every 8th Student Id was picked for the
sample. Then, we analyzed the data using descriptive statistics, confidence intervals,
hypothesis testing, and regression analysis to evaluate the relationships among the various
variables in the data set.
Data Analysis
In the sample of 200 students, 68 percent of students were enrolled in the accounting
major while 32 percent were enrolled in the business major.

Proportion of Students in the two Majors
Figure 1: Chart Showing the Proportion of Students Enrolled in the two Majors.
Of the students enrolled in the accounting major, 40 percent are female and 60 percent
are male. On the other hand, 45 percent of the students enrolled in the business major are
female and 55 percent are male. Therefore, from the sample we can say that there are more
male students enrolled in the accounting major compared to the business major.

Most of the student, which is 33.5% of sample, had a final grade of PA, with more
male students than female student scoring PA in their final grade. 78 percent of students who
attained grade CR were male while only 22 percent were female. Only 8.5% of the students
scored the highest grade, HD, with 53% of them being male and 47% being female. There
was a very slight difference in between the genders for the 15.5 percent of students who
scored D in their finals. There was an equal number of males who scored N and CR in the
finals. However, more female students scored N than CR in their finals.

In the business major, most student scored either N or PA in their finals. This number
makes up 75 percent of the students in the sample who have enrolled for the business major.
However, more accounting major students got a final grade of PA. There were more students
who attained the highest grade, HD in the accounting major than in the business major. This
was also similar for the grades D and CR. Almost the same number of students scored N in
both majors.

The sample average mark in the finals for the accounting major is 57.59 while the
sample average mark in the business major was 46.27. Overall, a female student seem to
perform better than a male student. This is because the pivot chart below show that the
average final score for female students was 54.57 which is greater than the average final
score of male students at 53.53.
The standard deviation is used to measure the variation of set of data relative to its
mean. In the sample, the standard deviation of the final score for female students and male
students is 21.50 and 21.58 respectively. Hence, the marks obtained by female students are
less variable than those of male students.
