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.
