What are the best coding classes in Lancaster?
The Lancaster district had 142,934 usual residents at the 2021 census, and 8.9% of them were aged 20 to 24, against 6.0% across England. Lancaster Castle says its beginnings date back to Roman times, on the hill above the town and the River Lune, and that it was a working prison until 2011. Lancaster learners from six to sixty-seven can join our teachers in India in live video lessons, alone or in a class of five to ten at the same level, at times planned around the UK day. Lesson one costs nothing, and from then on families pay USD 100 a month for a group place or USD 150 for a teacher of their own.
The River Lune at Caton, just upstream of Lancaster, has its flow measured every day. Our teenagers take the highest flow of each year from 1980 to 2023 and compare the two halves. The recent 21 years average 851.6 cubic metres per second at their peak, the earlier 21 years 783.2. Is the river flooding more? A permutation test answers without any formula: shuffle the 42 yearly peaks into random halves 100,000 times and see how often chance alone produces a gap that large. It does so about one time in five. Remove the single biggest flood, 1,740 cubic metres per second in December 2015, and the gap almost vanishes.

| Measure | Lancaster | England |
|---|---|---|
| Usual residents | 142,934 | 56,490,048 |
| Living in households | 134,704 | Not compared |
| Living in communal establishments | 8,230 | Not compared |
| Aged 15 to 19 | 10,707 (7.5%) | 5.7% |
| Aged 20 to 24 | 12,778 (8.9%) | 6.0% |
| Aged 70 to 74 | 7,955 (5.6%) | 5.0% |
| Students among residents aged 5 and over | 33,065 (24.3%) | 20.4% |
| Usual residents per square kilometre | 252.1 | 433.5 |
In 2021, 8.9% of residents were aged 20 to 24 and 7.5% were 15 to 19, both well above England, and 24.3% of those aged five and over were studying.
People aged 70 to 74 were 5.6% of the district, above England's 5.0%, in a district that runs from the city out to the Morecambe coast.
Student halls and other communal establishments housed 8,230 people in 2021, while 134,704 lived in ordinary households.
Our Lancaster groups draw on the whole district. A Year 4 child in Morecambe might be making a first game, a Year 12 student in Bowerham tackling A level Computer Science, and an adult in Carnforth learning Python for work, each in a small group at the right level.
From Lancaster Castle's own history page and Historic England's open listing data.
Lancaster Castle, often called John O' Gaunt's Castle, says its beginnings date back to Roman times, from a commanding position on the hill over the town and the River Lune.
The castle is owned by the Duchy of Lancaster and was a fully functioning HM Prison until 2011; today it is open for tours and events.
Historic England lists Lancaster Castle, the Priory and Parish Church of St Mary, the Ashton Memorial and the Lancaster Canal's Lune Aqueduct at Grade I.
The aqueduct matters for this page: it carries a canal over the very river our project measures. We have no connection with Lancaster Castle, the Duchy of Lancaster, Lancaster City Council, Historic England or the Environment Agency. The Lune is here because its daily flow record at Caton runs back to 1979, and a long record is exactly what you need to tell change from chance.
Where the flows come from
The Environment Agency's Hydrology service publishes the daily maximum flow of the Lune at Caton as open data from 1979, with a quality grade on every day. Water years run from 1 October to 30 September.
A permutation test asks how surprising a result is by rebuilding the world where nothing changed: shuffle the labels, recompute, and repeat thousands of times.
| Comparison | Earlier 21 years (1980 to 2000) | Later 21 years (2001 to 2023) |
|---|---|---|
| Average annual peak | 783.2 | 851.6 |
| Middle (median) annual peak | 773.0 | 778.0 |
| Years with a peak above 1,000 | 4 | 6 |
Keep water years with at least 90% of days recorded and a peak graded good or unchecked. Six years fail, including 2015 and 2024, whose peak days were estimated, leaving 42.
The later half averages 68.4 cubic metres per second more at its peak. But its middle value is almost the same, a sign that a few big years are doing the work.
Deal the 42 peaks into two random halves 100,000 times. A gap of 68.4 or more turned up in 21.0% of shuffles, so chance explains it comfortably.
The biggest peak in the record, 1,740 cubic metres per second on 5 December 2015, sits in the later half. Take that one year out and the gap falls to 24.0, with chance producing it more than a third of the time. The second lesson is subtler. We tried every possible split year with at least eight years on each side, 26 splits in all, and one of them gave a result that looks significant at the usual 5% level. Search enough ways and something will always look surprising; the honest test fixes the question before looking.
None of this proves the river is not changing. Forty-two years is short for floods, and a permutation test with 21 years a side can only detect large shifts. What the project shows is that this record, on its own, cannot tell a real rise from the luck of the draw, and that the other big years, 1,400 in January 1995, 1,200 in January 2005 and 1,150 in February 2020, are spread across both halves.
Learned on the Lune, then used in medicine, sport, product testing, climate science and anywhere two groups of numbers look different.
| Question | For the Lune peaks | What goes wrong if you skip it |
|---|---|---|
| Which years are trustworthy? | Complete years with good or unchecked peaks: 42 | Estimated peaks shaping the answer |
| Was the question fixed first? | Two equal halves, chosen in advance | Hunting for the split that looks dramatic |
| One-sided or two-sided? | One-sided p 0.21, two-sided 0.42, both reported | Picking whichever looks stronger |
| How much does one value matter? | Rerun without the December 2015 year | A single storm read as a trend |
| What could the test detect? | Only large shifts with 21 years a side | No difference read as proof of no change |
The second row is where most real mistakes happen. It is easy to look at a chart, spot where the numbers seem to jump and test exactly there. Doing so guarantees a surprising result sooner or later. Deciding the comparison before looking, and saying how many comparisons were tried, is what keeps a test honest.
Shuffling cards between two piles again and again, and counting how often the piles differ by as much as a real result.
Four decades of Environment Agency flows in Python, a permutation test built from scratch, and a check of how one flood changes it.

Python Automation CourseData Science CourseBecause spotting a pattern is easy, and knowing whether chance could have made it is the real skill.
AI tools are very good at finding patterns, including patterns that are not really there. A learner who has shuffled 42 years of Lune peaks and watched chance produce the same gap one time in five will ask the right question of any trend a tool reports: how often would this happen if nothing had changed?
The split-point trap is one of the most common ways analysis goes wrong, by people and by automated tools alike. Seeing one of 26 splits look significant, on data with no clear change, is a lesson in why good practice fixes the question first and reports every attempt.
So a Lancaster teenager should keep learning to code in 2026, beside a river with a long memory: machines will always find a pattern, but someone has to ask whether luck alone could have drawn it. The longer argument is in why coding is worth learning in 2026.
The district reaches from the city to the Morecambe coast and the villages of the Lune valley. Online, each of them is equally close to the lesson.
A learner in Heysham and another in Caton can share a class without anyone crossing the Lune.
A Lancashire pupil will find our levels familiar, since they track the English curriculum from Reception, through each Key Stage, to GCSE and A level, and all teaching is in English.
Even the free session is spent on a real task, and afterwards we suggest a level, a course and a regular slot; nobody asks for card details.
Five to ten learners at one stage, from Lancaster, around the UK and abroad, which keeps sensible times open at every level.
Two fixed lessons weekly, about eight a month, with half terms and exams arranged with the teacher in advance.
When it is 5 pm in Lancaster it is 9.30 pm for our teachers in summer and 10.30 pm in winter, because the clocks in India never change; they plan their working day around UK learners.
Across north Lancashire and beyond
Families in Garstang, Kendal, Kirkby Lonsdale or Fleetwood join exactly the same classes, since every group is online and set by level.
The first lesson is free, then there is one fee a month.
A full lesson with no charge, finishing with advice on level, course and a weekly time.
About eight live lessons a month, with five to ten learners at the same stage.
About eight live lessons a month, with the teacher working with your learner alone.
Hest Bank and Torrisholme families pay in US dollars, just like every family outside India, and our site carries no pound prices anywhere. No invoice arrives until after the free lesson, once a course and a weekly time have been chosen, and our pricing page covers what happens with pauses, missed lessons or a change between group and one-to-one teaching.

We choose the opening task to suit whoever is learning: a card-shuffling game for a young child, a short Python program that shuffles a list for a beginner, or four decades of Lune flows and a permutation test for a teenager ready for real data.
What Lancaster families ask us most often.
Census 2021 counted 142,934 usual residents in the City of Lancaster district, which includes Morecambe, Heysham and Carnforth; 134,704 lived in households and 8,230 in communal establishments.
It has many students and young adults: 8.9% of residents were aged 20 to 24 in 2021 (England 6.0%), and 33,065 of the 136,193 aged five and over were studying, 24.3% against 20.4%. Density was 252.1 residents per square kilometre.
A way to judge whether a difference between two groups could be down to chance. You shuffle the group labels many times, recalculate the difference each time, and see how often shuffled data produces a gap as large as the real one.
This record cannot say. Annual peaks at Caton averaged 851.6 cubic metres per second in 2001 to 2023 against 783.2 in 1980 to 2000, but shuffled data produced a gap that large about one time in five, and without the December 2015 flood the gap is only 24.0.
From the Environment Agency's Hydrology open data: the daily maximum flow of the River Lune at Caton from 1979, using only complete water years whose peak day was graded good or unchecked.
Lancaster Castle says its beginnings date back to Roman times and that it was a working HM Prison until 2011; it is owned by the Duchy of Lancaster. Historic England lists it at Grade I. We are not connected with the castle.
Weekday afternoons and evenings or weekends, at a UK time chosen in the free lesson. India is four and a half hours ahead of Lancaster during British Summer Time and five and a half hours ahead in winter.
No. We have no Lancaster centre and no premises in the UK, since all lessons are live online. A learner needs a computer with sound and a good connection, and our phone number is Indian.
The first lesson is free. After that, a group place is USD 100 a month for two live lessons a week, around eight a month, with five to ten learners; one-to-one teaching on the same pattern costs USD 150 a month. Nothing is charged until the course, format and time are agreed.
By level, pace and goals rather than age or where they live, with five to ten learners at the same stage. If no group fits the learner's week, we offer one-to-one lessons.
