Finding the closest school [formula vs. pivot table approach]
First a quick personal update: There has been a magnitude 7.8 earth quake in NZ on 14th November 2016 early morning. It is centered in Kaikoura, which is about 250 km away from Wellington. We did feel several shakes and after shocks. It has been an interesting and often scary experience. But my family is safe. I feel very sad for the all the damage and the loss for families in NZ. If you suffered from this quake, My prayers and thoughts are with you.
Yesterday, a friend asked me an interesting question. He has school distance data, like above. He wants to know which is the closest school for each school.
There are a few ways to answer this question. Let’s examine two approaches – formulas & pivot tables and see the merits of both.
