Quantitative Methods Report: Student Environmental Perception Analysis

This report presents a quantitative analysis of student demographics and environmental perceptions in Australia. The study examines the gender distribution, height, and family time of students in VIC and NSW, utilizing both nominal and ratio scale data. Descriptive statistics, including averages and standard deviations, are computed to provide insights into the sample characteristics. The report explores students' attitudes towards environmental conservation, such as installing water tanks and powering off main switches. Furthermore, the study employs linear regression models to assess the relationship between hours spent in paid work and weekly income. The findings reveal differences in gender distributions, height, and family time between the two states. The regression analysis indicates no significant association between work hours and income. The report concludes with recommendations for promoting environmental awareness among students. The analysis was performed using Excel Spreadsheet, and the data was analyzed to understand the characteristics of the population and the relationship between the variables.

Introduction
This paper is designed in understanding the demographic distribution of the students in
Australia. Also, the report will evaluate students’ perception of environmental issues. Both
nominal and ratio scale data will be collected. For instance, the height of the students
(without shoes), number of hours slept, among others. These are vital as they help in giving a
descriptive overview of the sample, which can help understanding the characteristics of the
population. On the other hand, the nominal scale data are vital in understanding the most
profound.
Analysis
In this section, the analysis will be subdivided into two parts, in which the analysis of two
states will be performed. A comparison will be carried out to assess how the student from
VIC and NSW use different strategies to conserve the environment. The analysis will be
performed by Excel Spreadsheet.
VIC state data analysis

Figure 1 shows that there is a higher chance of randomly selecting a female student (52.50%)
than the male (45.00%) and others (2.50%) (Keller, 2014).
The average height of student was computed and is as summarized below.

The summary of descriptive statistics indicates that the female student’s height (165.57 cm) is
slightly higher than that of male students (157.89 cm). However, the standard deviation of the
male student is higher than that of female students suggesting that the male student’s height is
not consistency like that of female students.
An assessment was carried out to determine time spent with family. The results are as
summarized.

to conserve the environment. The summary of this by gender is as illustrated below.

male and female is equal. That is, they have equal percentages (30.0%). On the other hand,
22.5% of the female compared to 15.0% have installed a water tank. This shows that in VIC
state, more female students install a water tank to conserve water.
A similar analysis was carried out to determine the proportion of students that power off the

A simple linear model was fitted to determine whether there is a relationship between the
number of hours spent engaged in paid work per week and the amount of money received per
week. The model summary and coefficient are as summarized below. The hypothesis tested is

QUANTITATIVE METHODS
H0: there is no relationship between the number of hours spent engaged in paid work per
week and the amount of money received per week. Versus HA: there is a relationship between
the number of hours spent engaged in paid work per week and the amount of money received
per week.

The results show that we should fail to reject the null hypothesis (p = 0.171) (Montgomery,
Peck, & Vining, 2012). This means that there is no significant association between the
number of hours spent engaged in paid work per week and the amount of money received per
week.

also more sensitive about installing a water tank as a measure of saving water.

The summary indicates that there is no sufficient evidence to reject the null hypothesis (p =
0.778) (Heiberger & Holland, 2015). This means that there is no association between the
number of hours spent engaged in paid work per week and the amount of money received per
week. In particular, the coefficient of determination can explain only 0.21% sources of
variation, meaning 99.79% sources cannot be explained.
Comparison
The summary of the distribution of gender in both states is similar, where the number of
female students is higher than that of male students. On the other hand, the male students in
NSW are taller than the female unlike in the VIC state where female students are taller. In
both cities, male spend less time with their families, as compared to female students. Unlike
in the VIC (4 hours) students in NSW spend more time doing family chores with an average
of 7.125 hours. Also, the male students in NSW spent slightly more time than female student
which is opposite in VIC state. In both cases, the fitted regression model was not significant.
This means that the between the number of hours spent engaged in paid work per week in
both cities are not good predictors of the amount of money received per week.
Conclusion
The results indicate that the between the number of hours spent engaged in paid work per
week is not associated with the amount of money received per week. Therefore, this means

QUANTITATIVE METHODS
that the number of hours engaged in paid work cannot be used as a determinant of income or
money received by students. The research indicated that female students in both cities are
more sensitive than the male students in Installing a water tank as a measure of conserving
water. Therefore, there is a need to enlighten the male students on the need to conserve the
water.
