#AFLW 2019

The 2019 AFLW season starts on Saturday with the opening game between Geelong and Collingwood (link to fixtures).

I have some data from last year’s regular season (link) curated as secondary data from the official AFLW web site (link).

Median Profiles

A Violin Plot created with BoxPlotR (link). (W1Q is the winning team, L1Q is the losing team).

Plot information

These data have given me an opportunity to postulate some naive priors about when points will be scored in the 2019 season. The probabilities per quarter are based upon game outcome so that the labels ‘winning’ and ‘losing’ relate to the game not the quarter.

A Box Plot Look at the Super Netball 2018 Grand Final

The 2018 Super Netball Final between West Coast Fever and Sunshine Coast Lightning takes place on 26 August at the Perth Arena.

I have followed this season’s competition results through the data supplied by Champion Data.

I have used BoxPlotR to visualise the data in an attempt to identify how the Final might be played.

West Coast

Centre lines show the medians; box limits indicate the 25th and 75th percentiles as determined by R software; whiskers extend 1.5 times the interquartile range from the 25th and 75th percentiles, outliers are represented by dots. There are n = 15 sample points.

Data summary:

Sunshine Coast


Centre lines show the medians; box limits indicate the 25th and 75th percentiles as determined by R software; whiskers extend 1.5 times the interquartile range from the 25th and 75th percentiles, outliers are represented by dots. There are n = 16 sample points.

Comparison Plot: West Coast and Sunshine Coast

Centre lines show the medians; box limits indicate the 25th and 75th percentiles as determined by R software; whiskers extend 1.5 times the interquartile range from the 25th and 75th percentiles, outliers are represented by dots. There are 15 sample points for West Coast and 16 for the Sunshine Coast.

The data suggest a close game. I am keen to see how the Sunshine Coast stay in contact with the West Coast as the away team, particularly in the final quarter.

Commonwealth Games 2018 Netball Tournament (#GC2018Netball)

There were 38 games played in the 2018 Commonwealth Games Netball Tournament. Just one of these games, Scotland v Barbados, required extra time to determine the winner of the game.

A box plot (using BoxPlotR) of the 37 games played in regular time is:

Centre lines show the medians; box limits indicate the 25th and 75th percentiles as determined by R software; whiskers extend 1.5 times the interquartile range from the 25th and 75th percentiles, outliers are represented by dots; width of the boxes is proportional to the square root of the sample size. n = 37 sample points. Winning teams are shown in light green, losing teams in light blue.

Overall, the median profiles and ranges in the 37 games were:
