Ingamells into a single theory in a logical way - the most advanced book on sampling that can be used by all sampling practitioners around the world.
Francis Pitard’s book does not deal with the sampling of human populations but it is exactly the same kind of error that is committed when sampling the contents of a coal or iron ore railwagon by taking a couple of scoopsful on top of the load and in many other instances which will be reviewed in this book full of practical examples.
