Note: Stratified vesus random samples. In some cultures more people walked in front of the tape recorder than others. Public songs versus private (sacred songs). Norman Berkowitz: Do cultures have sacred songs that they don't sing to outsiders that will be under-represented? Alan Lomax: I don't think that the songs differ in style. A basic finding of the study is that style supervenes function - with partial exceptions. Cantometric areas more reliable than Murdock Provinces. Gold analysis (analyzing frequency of occurrence of a sample that has been selected to have equal size in every province) versus simple analysis (finds mean occurrence, does analysis of these). How to check a smaller sample for accuracy: take 20 samples, split them in half and compare modal frequencies. Significance of first case versus subsequent cases. Checking through random resorts. (Alan Lomax: None of the people who object to the system would understand it.) Adjunct cultures. Weight the experiment against you. If you limit the randomness it would weight it against you. Prune the less useful samples. Set it up so that it can be used with, say, a week of training. A few can use all of it, but many could use some of it.
