Second half of semester

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

  • Four of the workshops cover common statistical analyses. Each is three hours long and there is plenty of time to do practical examples to check you understand the material.
  • The fifth workshop is a practical computing class. There are multiple identical one-hour sessions held each semester on using SPSS (version 22) to do hypothesis tests for means. Note that these sessions will not be held in Summer Semester 2018 although students may find the resources below useful for Assignment 3.

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.


Hypothesis Tests: Proportions [HTP]

Includes for a single proportion and difference between two proportions.

In Summer Semester, 2018 this workshop was held as follows: Sat 3 Feb, 10am-1pm, LibB28 (Basement of the General Library)

What's this workshop all about? 

This three-hour statistics theory workshop covers appropriate statistical analyses for exploring single proportions and differences between two proportions (i.e. one and two categorical variables). 

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 [HTM]

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

In Summer Semester, 2018 this workshop was held as follows: Mon 5 Feb, 10am-1pm, LibB28 (Basement of the General Library)

What's this workshop all about? 

This three-hour statistics theory workshop covers appropriate statistical analyses for exploring differences between means (averages). 

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.

Chi-Square Tests [CST]

In Summer Semester, 2018 this workshop will be held as follows: Thu 8 Feb, 10am-1pm, LibB28 (Basement of the General Library)

What's this workshop all about? 

This three-hour statistics theory workshop looks at the Chi-square test for independence (two categorical variables).

Please bring your calculator!

Topics covered include: 

  • Chi-square test assumptions
  • stating hypotheses
  • doing the test by hand including calculating expected counts, the Chi-square test statistic and degrees of freedom
  • interpreting computer (SPSS) output

Regression and Correlation [RC]

In Summer Semester, 2018 this workshop will be held as follows: Fri 9 Feb, 10am-1pm, LibB28 (Basement of the General Library)

What's this workshop all about? 

This three-hour statistics theory workshop looks at simple linear regression - fitting straight lines to data - and correlation (two numeric variables). 

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 in SPSS [HTS]

Note that these sessions will not be held in Summer Semester 2018 although students may find the resources below useful for Assignment 3.

In Semester Two, 2017 eight identical sessions of this workshop will be held as follows: 

  • Tue 3 Oct, 3-4pmComputer Lab 302-150
  • Fri 6 Oct, 2-3pmComputer Lab 302-160
  • Mon 9 Oct, 11am-middayComputer Lab 302-150
  • Tue 10 Oct, 3-4pmComputer Lab 302-150
  • Fri 13 Oct, 2-3pmComputer Lab 302-160
  • Mon 16 Oct, 11am-middayComputer Lab 302-150
  • Tue 17 Oct, 3-4pmComputer Lab 302-150
  • Wed 18 Oct, 10-11amComputer Lab 302-150

Computer Labs 302.150 and 302.160 are on the first floor of Building 302 (Science Centre), next to the Stats Assistance Room - the easiest access is from Symonds St or via the Science Student Centre.

What's this workshop all about? 

This one-hour practical statistics 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. 

Topics covered include:

  • stating hypotheses
  • creating plots
  • carrying out hypothesis tests including t-tests and the F-test for 1-way ANOVA
