Why you should learn probability on statistics?
- because you can't perform "total inspection"
================================================================================
So, you perform "sample inspection"
sample=extract_sample(population)
statistic_value_from_sample=sample_inspection(sample)
statistic_from_population: which is what you really want to know
================================================================================
error=statistic_from_population-statistic_value_from_sample
================================================================================
The range of error:
- confidence interval
- hypothesis test
By using probability, people determin "confidence interval"
confidence_interval=predict_confidence_interval(statistic_value_from_sample)
================================================================================
hypothesis test
- Your exclaim: value should have been here
- Calculate "confidence interval"
- If statistic_value_from_sample is involved in "confidence interval"
your exclaim is false
