Unit description Unit description
This is an intermediate statistics unit, which covers both the design and statistical components of experiments common to psychological research. The importance of interpretation based on both the design and statistics components is emphasised, together with concepts of power and sample size requirements for efficient research. Statistical methods covered include: descriptive statistics; one-way and two-way analysis of variance; correlation; and regression and non parametric equivalents of ANOVA. The unit includes instruction on the presentation of statistical results in report formal. Practical classes are based on the use of the Stata statistical software.

General Assessment Information

There are 3 forms of assessment for PSY 248: weekly quizzes, two assignments, and two exams. Overall grades for the unit will be determined by adding together marks for each of the assessments described in this guide. See the university policy on grading for more information.

In PSY 248, you are encouraged to form study groups to revise course material and practice using STATA. However, any work you submit for assessment must be your own, including computations and written expression. In recent years we have had a number of problems with students copying other students' work and submitting as their own work. Firstly, we encourage students to discuss their work with each other, and working together can be especially beneficial for statistics. Both assignments are assessed for plagiarism via Turnitin upon submission.

It is in your interest to keep a (hard or electronic) copy of your submitted work. Firstly, to be able to produce the copy if your original goes missing, and, secondly, to be able to produce an unmarked copy in the case of requesting a re-mark. If you request a re-mark, you will need to submit an unmarked copy of your work, which will be marked by a different marker, and you will receive the revised mark which may be either higher or lower than the original mark. If you wish to request a re-mark you will need to contact the unit teaching staff.

The two assignments must be submitted online via iLearn/Turnitin. Assignments submitted by post or emailed to tutors/lecturers will not be accepted. Marked assignments will be released via iLearn/Turnitin. Please be sure to proofread your work, as no unattached "addendums" will be accepted. Please also note that iLearn can lag when large numbers of students are uploading documents at the same time. Submission time for assignments will be counted as the time the assessment was received, not the time the uploading began. Because of this, make sure you don't leave your submission to 8:55pm the day it is due! Late penalties will be applied to assignments that are received after the due time, at the rate of 10% mark per day beginning at 9:01 pm on the due date.

All requests for extensions must be made prior to the due date for the assignment. Request for Extensions for Assignments are granted by the Student Centre. Ordinarily, no extensions of time for submission of written work will be granted since ample time for preparation will have been given. If an extension is required for medical or other extenuating circumstances, students may request this in writing through ask.mq.edu.au with supporting documentary evidence (such as medical certificate, counsellor note, or similar). The staff in the Student Centre will make all decisions regarding extensions. Neither individual tutors nor the course convenor will grant extensions. Assignments will not be accepted after marked assignments are returned to students online via iLearn.

Weekly Online Quizzes

Due: 9pm Sundays
Weighting: 20%

The unit’s practical program is vital for students to have a first-hand understanding of the material and its application in psychology research. 

Each week (starting Week 1) there will be a set of practical tasks to complete before attempting that week's quiz and before the next week's Tutorial. Most weeks this will involve a data analysis task (involving Stata) and an interpretation task, although in some weeks outputs will be provided for interpretation. The requirement to complete an online quiz each week will help ensure that students keep up with the unit material week-by-week. Tutors will then work through the solution during tutorial sessions in the subsequent week. Solutions to quizzes and practicals will NOT be made available separate to tutorials. Access to STATA is required for these weekly quizzes. 

Weekly quizzes will be worth 2% each, for a total of 20% of your final mark.

Quizzes must be completed within iLearn by 9pm on the Sunday prior to the week in which it will be discussed. The iLearn system will not accept submissions after that time and a mark of zero for that week will be recorded if no quiz is submitted on-time without a valid medical certificate or other documented unforseen circumstances. Each quiz is completed via iLearn and you will receive your mark on completion of the quiz. The tasks must be completed individually by each student.

If there are technical problems associated with iLearn (e.g., error message and then being unable to complete the quiz), make sure you take a screen shot of any error messages that occur. If a screen shot of an error occurring within iLearn is sent to Rachel Kallen before the quiz deadline, and it is deemed to be an error occurring that was out of the student’s control, then a second attempt at the quiz will be granted, as long as the quiz attempt was commenced at least 2 hours before the quiz deadline, and must be completed before the first tutorial session that reviews that quiz. No second attempts will be granted under any circumstances without evidence of the glitch. Similarly, no second attempts will be granted if you begin your attempt too late and cannot complete the quiz before 9pm Sunday.

It is strongly recommended you complete your quiz well in advance of the 9pm deadline!

In the event of health or other issues that may prevent you from completing the quiz by the 9pm deadline, you may apply for Special Consideration to be exempted from 1 quiz only. If further issues are experienced no further exemptions will be granted and an alternate assessment task will be set for you to replace the missed quiz.


On successful completion you will be able to:
  • Appreciate the way statistical techniques are used to support theory in psychology
  • Perform analyses of simple and complex experimental designs in psychology

Final exam

Due: University examination period
Weighting: 40%

This will be a 2-hour exam conducted during the official university examination period. The exam period for Session 2, 2019 is from 11th November to 29th November, 2019. This exam will assess all new course material that has been covered in PSY248, including lecture content, tutorial content, and required readings.

You will be allowed to take into this exam up to 10 single-sided A4 sheets of summary notes (or 5 double-sided A4 sheets of notes), plus a calculator. These summary notes can be in any format (including hand-written, word processed, photocopied, etc - or a combination). Statistical tables will not be required. Overall the final exam will assess knowledge and understanding through interpretative tasks, and ability to apply knowledge gained to practical problem solving in psychology research. Your understanding of STATA is examinable including use of STATA syntax (commands).

You are expected to present yourself for examination at the time and place designated in the University Examination Timetable. The timetable will be available in Draft form approximately eight weeks before the commencement of the examinations and in Final form approximately four weeks before the commencement of the examinations. http://students.mq.edu.au/student_admin/exams/

The only exception to not sitting an examination at the designated time is because of documented illness or unavoidable disruption. In these circumstances you may wish to consider applying for Special Consideration. Students who experience serious and unavoidable disruption, must apply for special consideration via ask.mq.edu.au. Any enquiries can be lodged online or via a visit to the Student Centre (ground floor, 4 First Walk [C3A])

If a Supplementary Examination is granted as a result of the Special Consideration process, the examination will be scheduled after the conclusion of the official examination period. The format of a supplementary examination is at each unit convener’s discretion and is subject to change from the original final examination. Supplementary Exams are only offered to students who have satisfactorily completed all other assessments for the unit and were unable to sit the final exam because of documented illness or unavoidable disruption.

It is the student’s responsibility to follow the steps provided via online or in person enquiries. An email will be sent to the student advising them of the outcome of their request for a supplementary exam. Students who are granted to sit for a supplementary exam must make themselves available to sit for the supplementary exam on the specified date. There will only be one time. It is the student’s responsibility to email Student Centre to confirm attendance at the supplementary exam.

You are advised that it is Macquarie University policy not to set early examinations for individuals or groups of students. All students are expected to ensure that they are available until the end of the teaching semester, which is the final day of the official examination period.


On successful completion you will be able to:
  • Appreciate the way statistical techniques are used to support theory in psychology
  • Perform analyses of simple and complex experimental designs in psychology
  • Critically evaluate designs and analyses in experimental psychology

Delivery and Resources

Lectures

There are three hours of lecture per week. These lectures will be recorded via Echo360 (which captures the data projector and the lecturer’s voice) and will be available on the iLearn page following the lecture. 

Tutorials

Tutorial demonstrations run from Week 2, are delivered online via iLearn, and will take approximately 1 hour each week. Tutorial demonstrations are an essential aspect of this unit. Quiz answers will not be available outside of tutorials (with the exception of Week 1).  

Technology

Students must have access to STATA, a statistical software package, for this course. STATA can be accessed on students' own computer online via iLab. See https://wiki.mq.edu.au/display/iLab/About for more information about accessing STATA via iLab. 

You will also be expected to access the PSY248 unit iLearn page at least weekly for unit notices and information regarding data files etc.

You are expected to have had prior experience in the use of STATA before coming into PSYC105, and be able to read raw data files, access pre-existing data files and retrieve STATA data files. You are also expected to have some knowledge of syntax in STATA. 

Technical Support 

If you experience technological difficulties with iLearn or iLab, make sure you take a screenshot of any error messages or difficulties that occur, and contact the university's technical support team via OneHelp. Raise and track requests directly at onehelp.mq.edu.au. Alternatively, you can log an issue by calling the IT HelpDesk on (02) 9850 HELP (4357), email onehelp@mq.edu.au. Because iLearn and use of Stata are fundamental to PSY248, it is your responsibility to make sure you can access both throughout the semester, especially when needed for weekly quizzes and the assignments.
