AI數字分析領航者  AI底層數據建模Sep 9, 2023

台灣高中的108課綱中，數學課程不只有機率( #probability )，還有統計學( #statistics )。統計分析基礎在樣本平均數(sample mean)，以及中央極限定理(central limit theorem)。

兩者讓樣本平均數的抽樣分配，有趨近常態分配(Normal distribution)的特性，並能使用Z分配(Z distribution)的臨界值表(critical value table)做信賴區間(confidence interval)和假設檢定(hypotheses and test)。

幸運的是，過去你無法驗證中央極限定理，現在已經有軟體可以讓你學習影響中央極限定理的各種因素，如何影響樣本平均數的抽樣分配趨近常態分配。

MATHS QUIZ. If I have a 9 inch diameter bucket, that's 8 inches deep, assuming the bucket is the same diameter at the base, how many litres of water can that bucket hold? (nicely mixing metric and imperial, there) #mathsmastodon #mathmastodon

Ah, coincidences, aren't they fun? The Mathnificent WoW (word-of-this-week) was "locus" and then I heard it used this morning in this excellent @NPR report. In case you aren't familiar w/ the word: https://katelovesmath.com/mathnificent-wow/

Due to high demand, the Mathnificent WoW (your Mathnificent Word of the Week) is on my site. It used to only be available within my subscriber weekly email, but I'm happy (meaning: thrilled) to comply w folks requests 😁 #math #maths #mathmastodon

I’m guessing whatever they are they are real. Like the ones in Disco that Stamets was working on. #sciencemastodon #mathmastodon #mathematics

Mathematics also had a strong year, with four Fields Medals being awarded for major breakthroughs in geometry, combinatorics, statistical physics, and number theory. The discipline also saw ongoing discussions about the impact of computers on the field.

it seems that for now #MathTwitter effectively became #MathMastodon (or simply http://mathstodon.xyz), whereas the rest of my Twitter neighbourhood pretty much stuck here

Complete induction like:

Step 1: Calculate 1+1.

Step 2: Calculate 1+2.

Step 3: Calculate abcdefg + Higgs² (donkey-wtf) + 1.

Done.
