BIOL12105 - Scientific Analysis and Statistics

General Information

Unit Synopsis

An understanding of experimental design, statistical methods, ethics and the ability to critically analyse scientific reports is essential for graduates in the sciences. In this unit, you will study experimental design, ethics and commonly used statistical procedures. You will be introduced to hypothesis testing and experimental design, parametric and non-parametric analyses, one, two and multi sample analyses (including one way, two way, and nested ANOVA designs, as well as multivariate analyses), correlation and regression, and data transformation. The learning and teaching strategy uses a clear, conceptual approach, which assumes that you have little or no statistical background.

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

This information will not be available until 8 weeks before term.
To see assessment details from an earlier availability, please search via a previous term.

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: Moodle feedback
Feedback
One student commented that they needed explanation about how to use the computer program for the second assessment.
Recommendation
A thorough walk-through tutorial explaining how to use the computer program was developed and recorded, and placed prominently on Moodle. I am not sure whether the student had problems viewing the recording, but the tutorial will be reviewed and updated if necessary for subsequent offerings.
Action Taken
The tutorial video and slides for using the computer program was updated to ensure current download sources and explanation of using the program was completely current.
Source: Email request and Moodle feedback
Feedback
A comment was provided from a student asking for feedback on drafts of assessment pieces.
Recommendation
Due to the quantitative nature of the unit and the assessment pieces, formally evaluating drafts is essentially the same as marking them (either the student has done the calculation correct or they haven't) and thus could provide unfair advantages to some students over others. Instead, I offered (and will continue to offer) generic feedback to indicate whether the student is on the right track with their choices of statistical tests and calculations.
Action Taken
Feedback was offered throughout term via the Moodle Q&A forum, individual emails, phone calls, and weekly live Zoom sessions. Students who took advantage of this additional help invariably passed the unit.
Source: Email and Moodle feedback
Feedback
Several students commented that the revised lectures and supporting resources better facilitated their grasp of what can be a conceptually and computationally difficult subject matter.
Recommendation
While such comments are pleasing, the unit content and delivery will continue to be revised and improved to maximise accessibility to students from diverse educational backgrounds.
Action Taken
Minor elements of the unit content were updated for term 2, 2020, including expanded examples from a broader array of research fields.
Source: Moodle feedback
Feedback
One student suggested that the unit could be improved by providing practice questions they could work through before the end-or-term quiz
Recommendation
Multiple past exams/quiz questions are already provided on the Moodle site, and additional questions will be provided in future offerings.
Action Taken
Nil.
Source: Emails
Feedback
There was some apparent confusion from a couple of students regarding the scope of the first assessment.
Recommendation
Upon review of the assessment description, there was some ambiguity in the language of the specific tasks set. The wording will subsequently be modified to remove this ambiguity.
Action Taken
Nil.
Source: Moodle feedback
Feedback
A comment was provided that noted the breakdown of the unit content into smaller, more digestible units helped their ability to learn and accumulate the knowledge across the length of the term.
Recommendation
This format will be continued for future offerings, with the recommendation that additional opportunities to deliver content in the same way be identified within the unit.
Action Taken
Nil.
