What are the best coding classes in Al Mudhaibi?
Al Mudhaibi is the largest wilayat in Ash Sharqiyah North, roughly 3,000 square kilometres holding two niabas and settlements of wildly different size. Average anything across places that unequal and the answer misleads. Anybody here between 6 and 67 can learn coding, Python, AI and mathematics with us, live and online. Placement is free of charge. A month in a group then costs USD 100, and a month one to one costs USD 150.
Sinaw and Samad Ash Shan are niabas of the same wilayat, and the villages under them range from a few families to whole towns. Take a rate for each place, average the rates, and a village of ten counts exactly as much as a town of four hundred. The local project shows how far that pushes the answer.

See the syllabusAl Mudhaibi is large enough and varied enough that any figure quoted for the whole of it has to say how it was put together.
Al Mudhaibi is the largest wilayat in Ash Sharqiyah North, estimated at about 3,000 square kilometres, sitting in the south west of the governorate and running into desert with golden sands. Area that size guarantees variety, and variety is what breaks a careless average.
Sinaw and Samad Ash Shan are niabas of Al Mudhaibi. That is a real administrative level between the wilayat and the village, and a dataset that has no column for it will quietly aggregate two very different places into one row.
Al Sudairah, Barzman, Al Zahib, Al Alia, Al Habat, Mahlia, Al Ghariyin, Al Khadraa and Bani Difaa all sit inside the same name, along with the Al-Dhaqiq area between Lazq and Al Maysar. Treating that list as a list of equals is the mistake this page is about.
An average has an implied weighting whether you chose one or not
Averaging a column of rates weights every row equally. Sometimes that is what you meant. Usually it is not, and nothing in the output records which of the two you were doing. Saying out loud what each row is worth is the whole of the fix, and it takes one sentence.
Named, measured and dated, with the scope of each claim stated.
Samad al-Shan is noted for ancient sites of the Umm al-Nar period, dated to roughly 2500 to 2000 BCE. A place with four thousand years of continuous record is a place where a dataset needs an explicit period column rather than a single date.
Suq Sinaw is among the most popular souqs in the country, trading dresses, khanjars and jewellery. A market with distinct product categories is a natural setting for learning why a category column beats a free-text description.
Agriculture is described as the first craft the population practised, with palm, lemon, alfalfa and vegetable crops alongside grazing and camel rearing. Five crop types on one landholding is five different yield series, not one.
The wilayat holds both cultivated land and a large stretch of desert. Averaging any per-area figure across ground that different produces a number describing nowhere in particular.
Because Sinaw is a niaba rather than a separate wilayat, records sometimes list it independently and sometimes fold it into Al Mudhaibi. A reader comparing two such sources without noticing will conclude something changed when nothing did.
The Al-Dhaqiq area is described as lying between the town of Lazq and Al Maysar. A place defined by what it sits between needs coordinates, not only a name, before anybody tries to measure anything about it.
No affiliation with any of the above exists or is claimed. Al Mudhaibi appears because a wilayat whose parts differ this much in size makes the averaging problem visible in a way a tidy example never could.
Five settlements, two totals, one honest question. Both answers below are arithmetically correct and they are nineteen and a half points apart.
Passes and entries, kept as two separate numbers. The learner does not store a percentage, because a percentage has already thrown away the thing that decides how much it should count.
Four small settlements at 90, 80, 70 and 90 per cent, and one large one at 55. The mean of those five figures is 77.0 per cent, and it is the number a spreadsheet gives you without being asked anything.
253 passes out of 440 entries is 57.5 per cent. That is the wilayat's actual rate. The large settlement holds 91 per cent of the learners and one fifth of the average, which is the entire distance between the two answers.
| Settlement | Passes | Entries | Its own rate | Weight in the mean of rates |
|---|---|---|---|---|
| Al Sudairah | 9 | 10 | 90.0 per cent | One fifth |
| Barzman | 8 | 10 | 80.0 per cent | One fifth |
| Al Zahib | 7 | 10 | 70.0 per cent | One fifth |
| Al Alia | 9 | 10 | 90.0 per cent | One fifth |
| Bani Difaa | 220 | 400 | 55.0 per cent | One fifth, holding 91 per cent of learners |
The mean of the five rates is 77.0 per cent and the wilayat rate is 57.5, a gap of 19.5 percentage points, computed before this was written. Neither figure is a mistake in arithmetic. The mistake is answering how are the settlements doing on average when somebody asked how is the wilayat doing.
Every rule below exists because a rate that has been computed too early cannot be combined with another one afterwards.
| Stage | Rule | What it prevents | What it gives you |
|---|---|---|---|
| Store | Keep passes and entries, not the percentage | A rate that cannot be recombined | Every level of aggregation stays available |
| Aggregate | Sum the parts, then divide once | A mean of means | The rate for the whole thing |
| Weight | If you do average rates, weight them deliberately | An accidental one-vote-per-row rule | A weighting you can defend |
| Label | Say which of the two a figure is | Two teams quoting different correct numbers | A figure that can be reproduced |
| Show n | Print the denominator beside every rate | A 100 per cent that came from one learner | A reader who can judge it |
Two bags of counters, one with ten and one with four hundred, each with a share coloured. Children work out the share for each bag and then for both together, and see for themselves that the second answer is not the average of the first two.
Python computes both figures from the same rows and prints the gap. The learner then writes the weighted version and checks it reproduces the totals answer exactly, which is the proof that the weighting was the missing piece.
The query changes from AVG of a computed column to SUM over SUM, the denominator is carried into every report, and any average of rates is labelled as one wherever it appears.
The settlement names are real and published. The pass and entry counts are teaching values, because no public per-village result file exists to copy, and the page labels them as such. The arithmetic is a property of averaging rather than of these particular numbers, which is why it is worth an hour of anybody's time.
The free class works out which rung is the useful one to begin on.
A half of ten and a half of four hundred are not the same amount.

MySQL DatabaseData AnalysisA wilayat this size cannot be served by one building, which is the practical argument for the class arriving at the learner.
Three thousand square kilometres, two niabas and settlements scattered between cultivation and desert. Any physical location would be convenient for a minority and a long drive for everybody else.
A real placement task, a real recommendation and no card requested. If the honest answer is a different course, that is what the teacher says before money is mentioned.
Matched on level and objective rather than by which village somebody lives in, which is a grouping a physical school could never manage here.
A single teacher and a single learner for an examination date or one specific problem with a deadline attached to it.
Eight in a normal month at a recurring agreed time, fixed once rather than rearranged around travel every week.
Oman is one and a half hours behind India. Harvest work, school terms, examination periods and Ramadan routines all belong in the conversation before a slot is fixed.
The question that only a person thinks to ask
A learner who averages a column of percentages has produced a number, and the screen offers no reason to doubt it. What changes them is somebody asking what that average is an average of, and then saying nothing at all while they discover the answer is rows, not learners.

The first task might be two bags of counters, both aggregates written in Python, or a real report the learner has had to defend to somebody.
Local detail, project method and service terms, kept apart.
No, and the page says so. The settlement names are real and published, and the pass and entry counts are teaching values because no public per-village result file exists to copy. The arithmetic being taught is a property of averaging rates, so it reproduces on any figures you substitute.
Because it gives every row one vote regardless of how many people that row represents. A village of ten and a town of four hundred contribute equally to the mean of the rates, which is almost never what anybody intended. The wilayat rate comes from dividing total passes by total entries, once, at the end.
No. No premises are claimed in Al Mudhaibi or anywhere in Ash Sharqiyah North. Classes are live online and need a laptop or desktop, working audio, a current browser and a stable connection. The page describes where the service reaches, not a building.
A niaba is an administrative level between the wilayat and the village. Sinaw and Samad Ash Shan are niabas of Al Mudhaibi. It matters because some records list a niaba separately and some fold it into the wilayat, so two sources can disagree without either being wrong, and a reader who has not noticed will think something changed.
Yes, up to 67. Adults take Python, databases, data analysis and automation. Anybody who reports a figure that somebody else acts on will get more from this project than a student will, and their own report makes the best exercise as long as the data is public or theirs to use.
Both aggregates computed from one dataset, a weighted version that reproduces the correct answer exactly, and the habit of printing the denominator beside every rate. That last one is one extra column and it makes a report arguable rather than merely believable.
The first class is free. Standard group tuition is USD 100 per month for two live lessons each week, normally eight lessons monthly. Standard private tuition is USD 150 per month for one learner with one teacher on the same usual frequency. Course, format, recurring time and availability are confirmed before payment.
A group normally contains five to eight compatible learners. Compatibility includes current level, learning pace and objective, not age alone. Private tuition is one learner with one teacher. If no suitable group is ready, a learner can discuss private tuition or wait for an appropriate cohort.
Oman is one and a half hours behind India. The teacher and learner agree a recurring time before payment, generally for two live lessons each week. Friday and Saturday options may be discussed subject to availability. School, work and transport schedules, examinations and Ramadan routines should be mentioned before confirmation.
The teacher establishes what the learner wants to be able to do and sets one task at that level. A child compares shares from two differently sized bags of counters, a teenager computes both aggregates and explains the gap, and an adult brings a real figure and is asked how it was put together. The teacher then recommends a course, a format and a time, and states the USD fee. Nothing is charged for it.
The Oman coding hub covers national delivery and fees. Read Ibra for refusing to hide a missing answer behind a zero, and Ash Sharqiyah North for the governorate this wilayat belongs to.
