Coding classes in Knocknacarra

What are the best coding classes in Knocknacarra?

A Knocknacarra learner meets a real teacher in every lesson, live on a video call, either with a handful of others at the same stage or alone, generally on two days a week, and anyone from six to sixty-seven can join. It all happens at home. Lesson one is free, and each month from then on is USD 100 for a shared group or USD 150 for private lessons.

At Galway Port, 5.5 kilometres from Knocknacarra's community centre, the Marine Institute runs two tide gauges about thirty metres apart, each logging the sea level every five minutes. Do they agree? Their readings correlate at 0.99995, which sounds like perfect agreement. It is not. One gauge reads 17.4 millimetres lower than the other on average, the gap nearly triples at low water, and two impossible readings, each claiming the sea stood 32.753 metres below datum, would on their own make the gauges seem to disagree by a third of a metre. This page teaches a learner how to measure agreement properly, and why correlation cannot.

Signature project

Two gauges, one sea: agreement is not correlation

Both gauges sit in Galway Port and report the sea level every five minutes to the Marine Institute; the comparison covers 1 January to 31 August 2026, with both series on the Ordnance Datum Malin scale. The program pairs readings taken at the same moment and compares them.

Galway Port and Galway Port 2, January to August 2026
MeasureResult
Readings paired at the same moment69,476, or 99.3 percent
Correlation between the two gauges0.99995
Average difference (first minus second)minus 17.4 millimetres
Limits of agreement (average plus or minus 1.96 standard deviations)minus 43.2 to plus 8.3 millimetres
Average difference at the lowest waterminus 37.9 millimetres
Average difference at the highest waterminus 12.9 millimetres

Near-perfect correlation

The two gauges correlate at 0.99995, because both follow the same tide up and down by metres every few hours. Correlation measures whether they move together. It would stay that high if one gauge read ten centimetres higher all the time.

A steady offset

Subtract one gauge from the other and the answer is not zero: the first reads 17.4 millimetres lower than the second on average, and the limits of agreement, the average plus or minus 1.96 standard deviations, run from minus 43.2 to plus 8.3 millimetres. In practice 93.6 percent of the differences fall inside them, a little under the textbook 95 because the differences are not perfectly bell-shaped.

Worse at low water

The difference depends on the level. When the sea is lowest, between 1.5 and 3 metres below datum, the average gap is 37.9 millimetres; at high water it is 12.9. A single average difference hides that the gauges disagree most when the tide is out.

To compare two ways of measuring, look at the differences

Two instruments can rise and fall together perfectly and still disagree, because correlation ignores any constant offset or scale error. The fairer method, often drawn as a Bland-Altman plot, puts the difference between paired readings against their average and reports the typical difference with limits meant to hold about 95 percent of them, then checks how many actually fall inside. It also shows at a glance whether the disagreement changes with the size of what is being measured, as it does here.

Step one of the learner's code fetches the two gauge records and matches every reading on one to the reading on the other taken at the same five-minute mark, which yields 69,478 matched pairs. Before any statistics it checks the values against what is physically possible, and finds two readings of minus 32.753 metres, one from each gauge on different days in July and August. Left in, those two numbers alone would stretch the standard deviation of the differences from 13.1 millimetres to 179.5 and make the limits of agreement about a third of a metre either way. With them removed, the program computes the average difference, the limits of agreement, the correlation, and the difference in bands of water level, and fits a line to show the gap growing by about 5 millimetres for every metre the sea falls.

Two readings out of 69,000

Each gauge produced one reading of minus 32.753 metres, far below any possible tide. Two bad values among tens of thousands would barely move an average, but a spread is built from squared differences, so they dominated it until they were removed.

Unknown quality

Every reading in both files carries quality flag 0, which the network defines as unknown rather than good. The impossible values show why a program has to check readings for itself.

Which gauge is right?

Comparing two gauges shows how far apart they are, not which one is correct. That would need a third reference, and the page does not say either gauge is in error.

Knocknacarra, named

Knocknacarra from its community centre, playgrounds and schools

Each fact below comes from the organisation that publishes it.

Playgrounds

Galway City Council's open data lists McGrath's Field Playground with a rubber wet-pour surface and no restricted opening hours, and Cappagh Park Playground with a wood bark surface and toilets at the adjacent community centre. The council's own file spells that second address Knockanacarra.

An Irish-medium school

Gaelscoil Mhic Amhlaigh says it spent 1993 to 1999 in temporary accommodation in Knocknacarra, moved into an eight-classroom building in 1999, and moved again in January 2018 to a new 24-classroom school at Miller's Lane.

A primary school

Knocknacarra Educate Together National School describes itself as a primary school in Galway City, and its website lists a STEM committee, Green Schools and an active schools programme.

What this page does not claim

No population is given for Knocknacarra, because the page prints only what named bodies publish about the place. The tide readings come from the port, 5.5 kilometres away, and the page makes no claim about flooding or water levels on the Knocknacarra shore.

Learning here

How a Knocknacarra learner's week goes

A usual week has two lessons, and the teacher leads each live from the first minute to the last.

Children

The youngest start with block code and measuring games, finding out that two rulers can disagree in a steady way.

Teenagers

Teenage learners work towards Python, building for the web, AI tasks and genuine sensor feeds from Galway Bay, testing every reading as they go.

Adults

No background is assumed for grown-up learners; the opening lesson points them to the right course.

Sea levels are the Marine Institute's published readings; the pairing, cleaning, correlation, differences and limits of agreement were calculated by us on 20 September 2026. Community centre and playground details come from Galway City Council's open data, and school details from the schools' own websites.

Ask an assistant whether the two gauges agree

It may report the correlation and stop.

Give an AI assistant both gauges' readings and ask whether they agree, and a common first answer computes the correlation, finds 0.99995 and declares near-perfect agreement. Correlation is the wrong tool for the question: it would be just as high if one gauge read ten centimetres low all year.

Someone who has done this project asks instead for the paired differences, their mean and limits of agreement, whether the gap shifts with the tide, and a check for impossible values before anything else. With those questions an assistant is a quick helper; without them it can produce a confident wrong answer.

Moving together is not the same as agreeing. The difference is one subtraction away. The longer argument is in the case for young people learning to program.

FAQ

Knocknacarra coding class questions

What Knocknacarra families usually ask.

Is there a Modern Age Coders centre in Knocknacarra?

No. We teach live over video and have no premises in Ireland. A learner needs a computer, a microphone and sound, and a dependable connection. The phone number on the page is in India.

What does the Galway Port project involve?

The learner compares the Marine Institute's two Galway Port gauges over eight months: they correlate at 0.99995, yet one reads 17.4 millimetres lower on average, the gap reaches 37.9 at low water, and two impossible readings of minus 32.753 metres would have made them look a third of a metre apart.

Is this page about flood risk in Knocknacarra?

No. The gauges are at the port and the project is about comparing measurements. Flood risk on the Knocknacarra shore is a separate question the page does not address.

Why is there no population figure for Knocknacarra?

District pages here repeat only what named organisations say about the place; for Knocknacarra that means Galway City Council and two schools, plus the Marine Institute for the port readings, and no resident count appears in any of them.

When are lessons held?

School days have slots from mid-afternoon to evening, and Saturdays and Sundays have daytime ones, all listed in Irish time. Our teachers are in India, five and a half hours ahead of Knocknacarra in the Irish winter and four and a half in summer, so we offer only hours that work in both places.

Do you teach adults?

We do, from complete beginners up to learners of sixty-seven; once the free lesson is done they settle on a same-level group or one-to-one teaching.

Will my child be with other Knocknacarra children?

Possibly, but groups are made by level, so classmates may be anywhere in Ireland or abroad.

What do coding classes in Knocknacarra cost?

The first lesson is free. Then a group place costs USD 100 a month for about eight live lessons, two a week, with five to ten learners, and one-to-one lessons on the same schedule cost USD 150 a month. Terms are agreed before any payment.

How many learners are in a group?

Five to ten, matched by level, pace and goals rather than age or address. If no group runs at a workable time, lessons are one to one.
