Coding and AI classes in Yorkshire and the Humber

The learner reads the three station files, keeps 2000 to 2020, and averages the monthly means. The window is chosen with care: Whitby's file records that its station moved in 2000 from a site 60 metres up to one 41 metres up, and mixing the two would blur the comparison. Then comes the adjustment. Each station's height in metres, multiplied by 0.0065, estimates how much cooler it is than it would be at sea level, so adding that amount puts all three on the same footing. The 0.65 degrees per 100 metres is a standard textbook average; real rates vary with weather.

Before adjustment, Whitby seems warmer than Bradford. After it, Bradford is warmer by about 0.4 degrees, and the adjusted order, Sheffield then Bradford then Whitby, matches the stations' latitudes from south to north: 53.38, 53.81 and 54.48 degrees. Height was hiding a north-to-south pattern. That does not prove latitude is the whole story, since the sea, towns and the exact site all play a part, but it shows why measured values should not be ranked before known effects are removed.

The unit slip is spectacular. The rate is 0.65 degrees per 100 metres, which is 0.0065 per metre. Use 0.65 per metre by mistake and Bradford's adjusted temperature gains 87 degrees. The learner writes the rate with its units in the variable name and adds a test that no adjustment exceeds a few degrees. A subtler check asks what happens if Whitby's older site is included: its 1991 to 1999 average was 9.45 at 60 metres, so the site change alone could shift a longer average.

Spotting an unadjusted comparison before it misleads anyone is a skill a Yorkshire or Humber teenager sharpens by coding in 2026. The longer argument is in why teenagers should still learn to code in 2026.
