Are the dune heights in the project real?
The published description of the Wahiba Sands is that the dunes rise over 100 metres high, and that is the fact the project is built on. The twelve individual heights are teaching values, because no per-dune survey is published to copy, and the page says so wherever they appear.
Why does capping a column survive review for so long?
Because it damages the ends of a distribution and leaves the middle alone. The mean moves a little, the median barely moves, and both stay inside the range a reader expects. The maximum and the spread are wrecked, and those are the two summaries people check least.
Is there a Modern Age Coders centre in Bidiyah?
No. No premises are claimed in Bidiyah 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 one check would have caught this?
Put a question to the finished file that the original source has already answered. The source says the dunes here go over 100 metres. Ask the file how many do. If the answer comes back as none, the file is broken, and finding that out took one query and one minute instead of a year and an argument.
Can an adult in Bidiyah study rather than a school student?
Yes, up to 67. Adults work in Python, data analysis and automation. Anybody who has ever written a reading down as below detection limit, or at capacity, or simply as more than, already knows this problem from the inside, and their own figures make the sharpest exercise wherever the data is theirs to use.
What does a learner have at the end of this project?
Three things. A file that marks which rows were capped, a summary written as a bound rather than as a result, and one assertion that fails on the broken version. All three keep earning their place long after the language stops being fashionable.
How much do Bidiyah 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 Bidiyah learners?
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 Bidiyah class times arranged?
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 Bidiyah class?
The teacher establishes what the learner wants to be able to do and sets one task at that level. A child orders a set of over cards and is asked which is tallest, a teenager caps a column and queries it, and an adult brings a real report and is asked which of its numbers are bounds. The teacher then recommends a course, a format and a time, and states the USD fee. That class is free.
