Confidence interval & CLT_Day8

warm up

 

The Central Limit Theorem (CLT) (중심극한정리)

 

 

when we do an experiemnt, we don't always know what distribution our data comes from.

실험할때 데이터가 어떤 분포로 형성될지 모른다

To this, "CLT" say who cares?

하지만 상관없다 CLT 라면

The sample means will be normally distributed.

sample 평균은 정규분포를 따른다
