Any survey of a place shaped like that will be complete in some parts and not in others. ### Villages along the water The population is dispersed among some 51 villages that mainly dot the fringes of the wilayat's major wadis. A settlement pattern that follows a river is a settlement pattern with a long edge, and long edges are where survey coverage runs out. ### Mountains between neighbours The mountainous landscape means two villages can be close together and awkward to visit in one trip. Whichever ones get missed will not be missed at random, which is worse than missing them at random. ### Water where you would not expect it Despite the terrain the wilayat is described as abundantly blessed with water. A place known for something is a place where a zero reading is genuine news, and genuine news deserves not to be confused with a blank. A spreadsheet has one way to show two completely different facts An empty cell might mean the quantity is zero, or that nobody measured, or that the measurement failed, or that somebody deleted it. All four look identical. Then somebody opens the file in a tool that helpfully fills blanks with zero, and the distinction is gone for good. Verified local facts ## Dima Wa Attayeen facts with a trail behind them Each claim traced, with the publisher named and the limits stated. ### Some fifty one villages The large majority of residents are described as living in some 51 villages. The word some belongs to the source. It is a count that is itself hedged, which is a fitting starting point for a project about incomplete records. ### Bordered on every side by named wilayats Dima Wa Attayeen borders Qurayat to the north, Ibra to the south, Al Qabil and Bidiya to the east and Al Mudhaibi and Bidbid to the west. A wilayat defined entirely by its neighbours is one whose edge cases genuinely are edge cases. ### Described as most abundant in water The wilayat carries a reputation for water in a country where that is worth remarking on. Where a quantity is the local headline, the difference between none and unmeasured stops being academic. ### Wadi Dayqah runs through it Wadi Dayqah is among the features associated with the wilayat. Named wadis are the spine the villages sit along, which is why the settlement pattern is linear rather than clustered. ### Arabian Tahr have been sighted here Sightings of Arabian Tahr have been reported in the wilayat. A sighting record is the purest example of the problem: no sighting today does not mean no animals today. ### A mountainous landscape The wilayat is described as distinctively mountainous while still being well watered. Terrain that makes places hard to reach is terrain that makes datasets uneven, and uneven is not the same as wrong. Modern Age Coders has no involvement in any of the above and asserts none. The wilayat earns its place on this page for one reason: a village count that arrives already hedged, in terrain that makes finishing a survey genuinely hard. Signature project ## Six dry villages, or eleven, from the same survey Nothing is mistyped and no arithmetic is wrong. Two entirely reasonable readings of a blank cell produce two answers, and only one of them is about water. ### 1. Survey the villages and write down what you find Forty villages report at least one active water source, totalling 140. Six are visited and genuinely have none. Five are never reached at all. Only the village count is published; the water figures are teaching values and the page says so. ### 2. Notice that two of those groups look the same in the file The six dry villages record zero. The five unvisited villages record nothing. In a spreadsheet a zero and a blank sit in the same column looking almost identical, and any tool that fills blanks makes them actually identical. ### 3. Ask the question somebody will act on How many villages have no active water source? Reading blanks as zero gives eleven. Excluding them gives six. The honest answer is six known, with five unknown, and that is the one sentence nobody writes. | Rule applied to blanks | Denominator | Mean per village | Villages with no source | | --- | --- | --- | --- | | Blanks treated as zero | 51 | 2.75 | 11 | | Blanks excluded, zeros kept | 46 | 3.04 | 6 | | Blanks and zeros both excluded | 40 | 3.50 | unanswerable | | Honest reading | 46 known, 5 unknown | 3.04 of those known | 6 known, 5 unknown | | Spread across the three rules | 51 down to 40 | 2.75 to 3.50 | 6 to 11 | | Difference that reaches a decision | n/a | 27 per cent | nearly double | ### The count is the number somebody acts on, and it is the one that doubles A mean drifting from 2.75 to 3.50 is a reporting problem. A count of villages without water moving from six to eleven is a budget, a lorry and somebody's drinking supply. The five unvisited villages might have plenty, and reading their blanks as zero puts them in a queue they may not belong in while leaving them unmeasured. Every figure above was computed before this was written. Reliable pipeline ## Give a gap its own value and never let a tool fill it Five habits, each cheap, and any one of them keeps the two facts apart. | Stage | Rule | What it prevents | What it gives you | | --- | --- | --- | --- | | Distinguish | Record not measured separately from zero | Two facts collapsing into one cell | A file that says which is which | | Refuse | Never let an import fill blanks with a default | A gap silently becoming a measurement | Data that stays as collected | | Count | Report the number of missing values beside every summary | Coverage nobody can see | A denominator a reader can check | | Qualify | Say known and unknown rather than a single total | A confident count built on absence | A statement that survives the next survey | | Revisit | Treat unmeasured as work outstanding, not as a result | A gap hardening into a fact | A list of places still to visit | ### For younger learners A row of cups, some empty and some never brought to the table, and the child asked how many cups have nothing in them. The cups that are not there are the lesson, and no screen is required. ### For teenagers The survey in Python with blanks held as a genuine missing value rather than as zero. The learner computes all three means, prints the coverage beside each, and writes the check that the denominator equals the number of villages actually visited. ### For adults Missing values stay missing through every import, summaries always print their coverage, and any headline count states how many records were unknown rather than quietly absorbing them. The some 51 villages figure, the wadi settlement pattern, the mountainous terrain, the water reputation, Wadi Dayqah and the Arabian Tahr sightings are published. Every water source count used in the project was invented for teaching, since no per-village survey has been published; that is stated at each point one appears. What the project demonstrates belongs to missing data generally and does not depend on the particular figures chosen. Learning ladder ## From counting empty cups to summaries that publish their own coverage One free class is usually enough to see honestly which rung a learner is on. Ages 6 to 10 ### Empty, and not there at all Children separate a thing with nothing in it from a thing that is absent. [Early Math Foundations](/courses/early-math-foundations)[Kids Coding Blocks](/courses/kids-coding-blocks-masterclass)Ages 11 to 13 ### Averages and who was counted Learners change the denominator and watch the answer follow. [Problem Solving and Computational Thinking](/courses/problem-solving-and-computational-thinking-for-kids)[Python and AI for Kids](/courses/python-ai-kids-masterclass)Ages 14 to 18 ### Missing values as first-class data Teenagers keep gaps as gaps all the way through a calculation. [Python for Teens](/courses/python-complete-masterclass-teens)[Data Science for Teens](/courses/data-science-course-for-teens-python-data)Ages 18 to 67 ### Reporting coverage, not just results Adults publish what they know and what they do not, in the same sentence. [Python Programming](/courses/python-programming-masterclass-zero-to-advanced-college)[Data and AI Analytics for Non-Programmers](/courses/data-and-ai-analytics-for-non-programmers-course)Delivery ## Live classes for villages strung out along the wadis A wilayat whose people live in dozens of small settlements along river courses has no location that is convenient for more than a fraction of them. ### Dozens of settlements, one lesson Where the population is spread along wadis rather than gathered in a town, only teaching that travels reaches all of it. Nobody has to be the one who lives furthest from the class. ### An opening lesson with nothing attached to it A complete class, a real task and a named recommendation at the end. No payment details are collected to arrange it, and nothing is agreed until a teacher has been watched teaching. ### Five to eight learners, matched on ability Groups form around what a learner can do now and what they want next. Which wadi they live on is not an input, and no local arrangement here could say the same. ### One to one for a narrow target One teacher with one learner, for a dated examination or a single specific gap that a shared plan would only be able to work around. ### Eight lessons across a normal month Two live sessions each week at a slot fixed once, when the learner enrols, rather than rebuilt each week around school, work and the road. ### Ninety minutes of clock between here and the teacher Oman runs that far behind India, and it is handled once. Term dates, working hours, examination seasons and Ramadan all go into the conversation before a time is agreed. A learner cannot see what is not in the file Nothing on screen distinguishes the village that has no water from the village nobody visited. What surfaces it is a teacher asking how many villages were actually surveyed, and then waiting while the learner discovers their own data cannot answer that.

FAQ ## Dima Wa Attayeen coding class questions Local facts, teaching method and terms of service, kept apart. ### Is the 51 village figure real? It is published as some 51 villages, and the word some belongs to the source rather than to us. That hedge is kept everywhere the number appears here. The water source counts in the project are teaching values, because no per-village survey is published, and the page labels them wherever they occur. ### Why is reading a blank as zero so tempting? Because it lets the arithmetic finish. A missing value stops a mean from computing and a zero does not, so the substitution turns an error into a result. The result is wrong and looks entirely normal, which is the worst combination available. ### Is there a Modern Age Coders centre in Dima Wa Attayeen? No. No premises are claimed in Dima Wa Attayeen 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. ### What is the correct answer when data is missing? Say what you know and say what you do not, in the same sentence. Six villages have no active source and five were not surveyed is a complete, useful and honest answer. Eleven villages have no water is a shorter sentence and it is not true. ### Do you teach working adults here, or only school students? Both, to an upper limit of 67. The adult track covers Python, databases and reporting. Anyone who has watched a dashboard drop sharply and then found that a feed had stopped rather than a number falling has already lived this exact confusion. Where the figures are yours to hand over, they make a far better exercise than ours. ### What does a learner have at the end of this project? A file where a gap is stored as a gap, a summary that prints its own coverage, and a headline figure written as known and unknown rather than as a single confident number. That habit survives every change of tool. ### How much do Dima Wa Attayeen coding classes cost? 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. ### What is the class size for learners here? 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. ### How are class times arranged for learners here? 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 travel schedules, examinations and Ramadan routines should be mentioned before confirmation. ### What happens in the free class? The teacher establishes what the learner is trying to become able to do and sets one task there. A child counts empty cups and then notices the ones that never arrived, a teenager computes three means with three denominators, and an adult is asked how many records behind one of their own figures were actually missing. The teacher then recommends a course, a format and a time, and states the USD fee. That class is free.
