This course aims to provide students who have limited knowledge of statistics, with the fundamental statistical concepts, methods and skills necessary in order to undertake or critically appraise quantitative methods and the interpretation of subsequent results. The course is aimed at developing statistical literacy and a strong foundation in threshold statistical competencies in students from a variety of disciplines, including science, psychology, the physical sciences, business, commerce, and IT and is a pre-requisite for most high-level statistics courses.
This course focuses primarily on the appropriate application, interpretation and communication of foundational descriptive and inferential statistical methods. Emphasis is placed on understanding the concepts and principles associated with dealing with data, in particular descriptive and inferential statistics. Data sets from a range of disciplines are included as well as examples of statistics presented in popular media. Core components of the course include the use of statistical software and the development of problem solving and quantitative skills relevant to many disciplines of study. Note: The mathematical underpinnings of the methods used are not covered; other statistics courses cover this aspect.
Course learning outcomes
On successful completion of this course students should be able to:
- Explore relationships in data and distinguish between different methods of data collection and analysis;
- Evaluate and apply a variety of statistical inferential methods to real life situations;
- Use a statistical computer package to enter, summarise and analyse data;
- Interpret and communicate the results of statistical analyses for a diverse audience.

Text and materials required to be purchased or accessed
1) a six-month license for a download version can be purchased online from the Australia and New Zealand distributors of SPSS, Hearne Software. Before deciding to choose the download option check that the size of the download is compatible with your internet quota and speed. Be aware that the SPSS student license only allows limited reinstalment within the designated license period from initial installation.
2) students can access SPSS free online through https://turbo.usq.edu.au/ using their USQ credentials to login (more information will be provided on the course Study Desk). This option requires reliable internet connection.
All additional study material will be provided on the course StudyDesk.
Student workload expectations
To do well in this subject, students are expected to commit approximately 10 hours per week including class contact hours, independent study, and all assessment tasks. If you are undertaking additional activities, which may include placements and residential schools, the weekly workload hours may vary.
