Introduction
Welcome to ETX1100 Busniess Statistics for Semester 1, 2010. This 6 point  unit is compulsory for the
Bachelor of Business  degree programme.
Unit synopsis
Students will learn to use basic statistical techniques and their applications to problems in accounting,
finance, management, marketing and business in general. Students should also be able to effectively
communicate the results of their analyses. This unit covers descriptive statistics for revealing the
information contained in data; probability as a tool for dealing with uncertainty and risk; probability
distributions to model business behaviour; estimation and hypothesis testing techniques for decision
making; simple tools for forecasting time series; and calculation and interpretation of basic price indices.
Excel is used extensively.
Learning outcomes
The learning goals associated with this unit are to:
interpret business data using descriptive statistics techniques, including the use of spreadsheet
functions
•   
apply simple concepts of probability and probability distributions to problems in business
decision-making
•   
describe the role of statistical inference and apply inference methods to single population means•   
evaluate relationships between variables for business decision-making, using the concept of
correlation and simple linear regression
•   
apply time series techniques of indexing, deflating and forecasting to business and financial
series and interpret the results.
•   
Contact hours
Two 1-hour lectures and one 1-hour tutorial per week
Workload
On-campus: This is a six credit point unit with three hours class contact per week over 13 teaching
weeks. The total time commitment expected for this unit is 156 hours. In order to meet the faculty's
expectation, students should plan to spend on average nine hours in self-directed study, in addition to
the three hours of class contact, each week.  Self-directed study includes time spent in preparing for and
completing assessment tasks, together with time spent in general study, revision and exam preparation.
Unit relationships
Prerequisites
Students enrolled in course code 2601 must be granted permission to study this unit. For all other
students, no prerequisites apply.

Prerequisites: Although a Year 12 mathematics subject is a prerequisite for entry into Bachelor of
Business, ETX1100 only assumes you have covered the basic mathematics from the first four years of
secondary school.

Teaching and learning method
On-campus:
This unit will be taught on Caulfield campus as a two-hour lecture and a one hour tutorial each week for
13 weeks.
Your study time will be far more effectively used if you concentrate on understanding the unit material,
rather than on mere rote learning. If you encounter difficulty with the unit material, you will need to invest
more time.  Furthermore, you should consult a tutor. Each tutor will set aside an hour each week
throughout the semester to meet with students for individual consultations. The times and locations for
consultations with these tutors will be provided on the unit Blackboard site from the second week of
semester.
