How to read the ANSI tables for inspections based on random sampling

This video shows how to read the ANSI tables (also known as AQL tables).

It's not always practical to inspect 100% of the products being produced by a factory. Therefore, random sampling is used, and these tables help you to ascertain the correct number of samples for inspection.
Random sampling is useful because using statistics to decide upon the samples is better than just a fixed percentage.

We will look at the two common sampling settings:
- Normal severity
- Level II

We need to be able to answer 2 key questions:
1. How many samples to check?
2. How to decide if a batch should be accepted or rejected?

This video will show you the answers to these questions.
