1. Introduction
The objective of the given report is to analyse the beverage preferences of students studying
at USC. In this regards, emphasis has been given on the segregation between international
and domestic students so that their preferences and price related behaviour can be compared.
A sample of responses of 100 students has been selected from the available population survey
data. The underlying sampling technique used for the same is simple random sampling which
has been executed using Excel as the enabling tool (Eriksson and Kovalainen, 2015). Each of
the elements in the population in this sampling technique has equal chance of getting
selected. Since this technique is a probability based sampling technique, hence the bias
would be limited in this sample (Flick, 2015).
2. Data Analysis
The objective of this section is to address specific questions that have been raised which the
report aims to address.
(1) The requisite screenshot for the selected sample is pasted below.
From the above, it is apparent 93% of the students in the sample are domestic students while
7% of the students are international students.
(2) The relevant data summarising the relationship between price and average quantity
consumed by students is indicated as follows.

The relationship can be studied by drawing a scatter plot with price as the independent
variable and average quantity consumed as the dependent variable.
From the above scatterplot, it is apparent that there is a significant negative linear relationship
between price and the average quantity demanded by the students. This is apparent from the
fact that correlation coefficient is quite close to the theoretical minimum of -1 (Hillier, 2016).
(3) The preferences of the selected sample with regards to most popular and least popular
beverage is summarised in the form of graph indicated below.
