All figures are for the suburb and locality. The bureau randomly adjusts small cells, so published parts are never added together on this page. Signature project ## Four models and three R squared scores The data is 23 months of entries at Wentworthville station, from 68,953 in January 2025 to 97,307 in March 2026. Each model is fitted by least squares on October 2024 to February 2026 and then asked to predict March to August 2026. | Model | Fitted on all 23 months | Held out, against the test mean | Held out, against the training mean | Average miss on held-out months | | --- | --- | --- | --- | --- | | Overall average | 0.000 | -5.598 | 0.000 | 7,331 | | Straight-line trend | 0.094 | -7.218 | -0.246 | 8,334 | | Month of the year | 0.875 | -2.411 | 0.483 | 5,103 | | Trend and month | 0.934 | -0.984 | 0.699 | 3,865 | ### Seen data flatters With 13 parameters and 23 points, the trend-and-month model scores 0.934 in-sample. Any model with that many knobs can follow the data it has already seen. ### The baseline decides R squared compares your errors with those of a plain average. Against the held-out months' own average the trend-and-month model scores -0.984; against the training average, 0.699. ### Negative is allowed A negative R squared means the model did worse than the chosen average. The straight-line trend does worse than either average on the held-out months. ### Which number would a library print? scikit-learn's `r2_score(y_test, y_pred)` uses the mean of y_test as its baseline, so it reports the -0.984 figure. That baseline knows the test period's average in advance, which a forecaster never does. Entry counts are Transport for NSW monthly Opal figures; the models, scores and errors are our own calculation. We give no reason for any month being high or low. Reporting a model ## What a fair report on the model includes Learners finish by writing the report a careful reader would want, using Wentworthville and its neighbours for scale. | Station | Average a month | Rank among 270 train stations with all 23 months | | --- | --- | --- | | Westmead | 151,164 | 35th | | Wentworthville | 87,159 | 58th of 270 | | Pendle Hill | 70,999 | 68th | ### Children Guess tomorrow's classroom temperature from a week of readings, then check the guess and say how far off it was. ### Teenagers Fit the four models, hold out six months and report every score with its baseline named. ### Adults Ask any vendor or analyst which data their accuracy was measured on, and against what. Transport for NSW releases the station figures under a Creative Commons licence and is unconnected with Modern Age Coders. Schools and the school year ## Four state schools across two councils The NSW school locations file lists four government schools with a Wentworthville address, two in Cumberland council and two in City of Parramatta. | School | Level | First teacher | Council | | --- | --- | --- | --- | | Wentworthville Public School | Primary | 1891 | Cumberland | | Darcy Road Public School | Primary | 1955 | Parramatta | | Pendle Hill Public School | Primary | 1955 | Cumberland | | Pendle Hill High School | Secondary | 1965 | Parramatta | ### Summer break Eastern division schools are off from Friday 18 December 2026 to Wednesday 27 January 2027. ### Autumn break 2027 Monday 12 April to Friday 23 April, after Term 1 ends on Friday 9 April. ### Holiday timetable Wentworthville classes also stop for these breaks and resume in their usual weekly slot. Learning ladder ## From guessing games to tested models The ages are guidelines; the free first lesson finds the right level.

[Data Science Course](/courses/data-science-complete-masterclass-college)[Statistics & Probability](/courses/statistics-probability-maths-course)Coding and AI ## High scores on seen data are easy to come by This is the most common way AI results mislead, and it needs no bad intent. An assistant asked to model Wentworthville's entries will happily fit the trend-and-month model and report R squared 0.934. Nothing in the output says the score was measured on the same months used for fitting, or that a fair test gives a very different number. Learners who have produced all three scores themselves ask two questions of any reported accuracy: tested on what, and compared with what. Those two questions are most of model evaluation. In 2026 anyone can fit a model with one prompt; Wentworthville learners who can test one honestly will be the ones others rely on. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Delivery ## Live lessons for Wentworthville learners at home Classes take place on live video, joined from home in Wentworthville. ### Real-time teaching Code and models are built during the class, with the teacher watching each step. ### Fits NSW schooling Teachers use NSW stages and years and plan around the state calendar. ### Trial lesson free One full lesson without charge, ending in a suggested course and time. ### Fifteen to twenty learners Groups share a level; individual teaching is available instead. ### Regular sessions Two a week at fixed times, close to eight a month, with breaks shared early. ### Teachers in India A 5:30pm Wentworthville lesson is noon India time in Sydney summer time and 1pm the rest of the year. Daylight saving and India Sydney moves to daylight saving from Sunday 4 October 2026 until Sunday 4 April 2027. India does not, so Sydney is 5 hours 30 minutes ahead during that time and 4 hours 30 minutes ahead otherwise. Lessons are always timetabled in Sydney time. Fees ## Wentworthville lesson fees A single flat price list for all courses. First class**USD 0** The opening lesson is free, and the teacher then suggests a course and a time. Group tuition**USD 100** Two group lessons a week, about eight a month, in a class of fifteen to twenty at one level. Private tuition**USD 150** Private lessons twice a week, again about eight a month. Wentworthville families pay in US dollars, and payment begins only after the trial has agreed a course and slot.

The 2021 Census QuickStats for the Wentworthville suburb and locality counted 15,098 residents, median age 33, in 3,926 families and 5,721 private dwellings. ### What is R squared? It is one minus the model's squared errors divided by the squared errors of a plain average. A score of 1 is perfect, 0 matches the average, and below 0 is worse than the average. ### Why can the same model get different R squared scores? Because the score depends on which data it is measured on and which average it is compared with. In the Wentworthville project one model scores 0.934, 0.699 and -0.984. ### How busy is Wentworthville station? From October 2024 to August 2026 it averaged 87,159 entries a month in Transport for NSW figures, 58th of 270 train stations with complete data by our calculation. ### Which state schools have a Wentworthville address? Wentworthville Public School and Pendle Hill Public School in Cumberland council, and Darcy Road Public School and Pendle Hill High School in City of Parramatta. ### What age can learners start? Scratch from six. Model-testing projects like this one suit learners from about 14 who know some Python. ### What setup is needed at home? A keyboard computer such as a laptop, desktop or Chromebook, a working microphone and sound, and a dependable internet link. ### Do you run classes in Wentworthville itself? No. We teach only online and have no premises anywhere in Australia, including Wentworthville. Our contact phone number is an Indian number. ### How much do Wentworthville lessons cost? The first lesson is free. A group place is USD 100 a month for two live lessons a week, about eight a month, with fifteen to twenty learners; one-to-one is USD 150 a month on the same plan. Nothing is charged before a course and time are agreed. ### How big are the groups? Fifteen to twenty learners, grouped by level and goals rather than age. If no group fits the learner's schedule, one-to-one lessons are offered instead.
