Second half of semester

Five workshops are held during the second half of the semester:

The first workshop is a practical computing class. There are multiple identical one-hour sessions held each semester on using SPSS to do hypothesis tests for Assignment 3.
The other four workshops are designed to be exam prep by Lecture Workbook chapter/s. Each workshop is three hours long and there is plenty of time to do practical examples to check you understand the material.
No registration required - just turn up!

Please make sure you bring your calculator with you to these workshops!

Please note that workshops in italics have already been held this semester.

Drop-in sessions are being held this semester as follows:

Assignment 3 drop-in session – Saturday 17 October, 9.30am-4pm, LibB10
Exam prep drop-in session – Saturday 24 October, 9.30am-12.30pm, LibB15
Exam prep drop-in session – Monday 26 October, 9.30am-4pm, LibB10 (note that this is Labour Day so there will be free parking available on Princes St if you arrive early enough! Public transport will be on the Sunday timetable…)
Exam prep drop-in session – Saturday 31 October, 1-4pm, LibB10

Come along in-person or online and ask Leila questions about anything Stats-related!

Regression and Correlation

In Semester Two, 2020, this workshop was held as follows: Saturday 31 October, 9.30am-12.30pm, LibB10 (Basement of the General Library)

What's this workshop all about?

This three-hour workshop looks at simple linear regression - fitting straight lines to data - and correlation (two numeric variables). It is excellent exam preparation for Chapter 10.

Please bring your calculator!

Topics covered include:

interpreting computer (SPSS) output including scatter plots
simple linear regression including the least squares regression line, its hypothesis tests/assumptions and residuals
making predictions (confidence/prediction intervals)
correlation

Hypothesis Tests: Proportions

Includes for a single proportion and difference between two proportions.

In Semester Two, 2020, this workshop was held as follows: Tuesday 3 November, 9.30am-12.30pm, LibB10 (Basement of the General Library)

What's this workshop all about?

This three-hour workshop covers appropriate statistical analyses for exploring single proportions and differences between two proportions (i.e. one and two categorical variables). It is excellent exam preparation for Chapters 6 and 7 (proportions).

Please bring your calculator!

Topics covered include calculating and interpreting t-tests and confidence intervals for:

a single proportion and
differences between two proportions

Hypothesis Tests: Means

Includes for a single mean, paired data and differences between two or more means.

In Semester Two, 2020, this workshop was held as follows: Tuesday 3 November, 1-4pm, LibB10 (Basement of the General Library)

What are these workshops all about?

These two three-hour workshops cover appropriate statistical analyses for exploring differences between means (averages). They are excellent exam preparation for Chapters 6, 7 and 8 (means).

Please bring your calculator!

Topics covered include:

initial data display and interpreting plots
hypothesis tests (t-tests and the F-test for 1-way ANOVA) including setting up hypotheses and interpreting P-values and confidence intervals.

Hypothesis Tests in SPSS

In Semester Two 2020, six identical sessions of this workshop were held as follows:

Session 1: Friday 16 October, 3-4pm
Session 2: Monday 19 October, 10-11am
Session 3: Monday 19 October, 2-3pm

All sessions were held in Lab 302-160 which is on the first floor of Building 302 (Science Centre), next to the Stats Assistance Room - you can access Building 302 from Symonds St or via the Science Student Centre (Building 301) or via the walkway by the Science Student Resource Centre (Building 303/303S).

No booking required – just turn up to the session that suits your timetable!

What's this workshop all about?

This one-hour practical workshop covers using SPSS to carry out hypothesis tests for numeric data where differences in means are explored. This workshop is suitable for students with little/no experience using SPSS. Stats 101/101G/108 students will find it very useful preparation for the SPSS work they will need to do in Assignment 3.

Topics covered include:
