STAT11048 - Essential Statistics

General Information

Unit Synopsis

This unit introduces students to the concepts and applications of probability and statistical modelling involving questions of estimation, inference, regression, and correlation. Topics covered include descriptive statistics, measures of central tendency and dispersion, probability and probability distributions (binomial, Poisson, normal), confidence intervals, one and two sample hypothesis tests, one way analysis of variance, chi-square tests, linear regression, and correlation. The use of a calculator and a statistical/spreadsheet computer package for data analysis are covered.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Written Assessment 20%
2. Written Assessment 20%
3. Take Home Exam 60%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Self reflection and student feedback.
Feedback
The current textbook is too old (a 2010 edition) and has a strong focus on US Business applications of statistics.
Recommendation
A new textbook is to be prescribed with a focus on Australian and New Zealand business applications of statistics and which has a more recent edition.
Action Taken
As recommended a new textbook was prescribed for Term 1, 2019 with a focus on Australian and New Zealand Business applications.
Source: Self reflection and student feedback.
Feedback
The Study Guide needs to be revised and updated.
Recommendation
A new edition of the Study Guide will be produced.
Action Taken
A new edition of the Study Guide was made for Term 1, 2019 as recommended.
Source: Self reflection and student feedback.
Feedback
The lecture videos need updating as there are some technical issues in the current videos and they use an old version of the Study Guide and an old version of the STAT11048 webpage.
Recommendation
A new set of lecture videos will be recorded using the new edition of the Study Guide.
Action Taken
A new set of lecture videos were made for Term 1, 2019 as recommended.
Source: Student feedback
Feedback
Some students find the maths very challenging in this unit. There is a need for more help for students who have little or no background in maths.
Recommendation
Identify additional resources that can be provided to students, e.g. online or face-to-face tutorials, to cover background math topics.
Action Taken
Some additional resources were found (eg. online probability calculators, YouTube videos) and placed on the unit website. Also on campus tutorials and online Zoom tutorials were run weekly for students.
Source: Student Feedback
Feedback
A glossary of Statistics symbols is needed in the Study Guide and on the Moodle website.
Recommendation
A glossary of Statistics symbols will be added to the Moodle website for the next offering and to the Study Guide when a new edition is written.
Action Taken
Nil.

Feedback
Use a math test at the start of Term to identify areas of math inadequacy.
Recommendation
Discuss this issue with the Maths group in the Academic Learning Centre and identify appropriate diagnostic test materials and resources.
Action Taken
Nil.
Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Introduce the basic concepts of data handling and statistical analysis including some considerations of sampling theory
  2. Introduce the concept of probability and consider the applications of several probability distributions to the solution of problems
  3. Draw statistical conclusions about a population based on a sample of data using one sample, two sample, and ANOVA tests
  4. Use a calculator and computer software to perform statistical calculations.

This unit is designed to provide a foundation in statistical thinking as applied to decision making in life.
