STAT1520: Economic and Business Statistics (Solutions) - at UWA

This unit covers basic statistics and is compulsory for Bachelor of Commerce students. Topics include displaying and summarising data; random variables and their distributions; normal and binomial distributions; sampling distributions and hypothesis testing; confidence intervals; t-tests and F-tests; regression and correlation; goodness of fit; chi-square tests; and introduction to analysis of variance. Use of statistical packages is an integral part of the unit and emphasis is placed on examples of particular relevance to economics and commerce students.

✔ Outcomes:

Students are able to (1) explain the basic probability concepts in modelling real-life situations in business and other applied disciplines; (2) identify independent events, and use conditional probability calculations and Bayes' theorem; (3) perform modelling using various distributions and calculate related probabilities, expected values, covariance and correlation; (4) demonstrate practical expertise associated with the use of a statistical package such as the Data Analysis Tool in Excel in performing basic statistical procedures; (5) distinguish between the different types of statistical tests that may be used to analyse data in different disciplines and understand subject-related practices of tests; (6) analyse relationships between variables using linear regression, and apply decision-making processes on the means for more than two populations based on ANOVA techniques; and (7) work effectively in both an independent and team situation, and complete required work and project reports by meeting deadlines.
