we are testing the acceptability of breadnut as a flour and we need to have a sampling design. im using the survey method and ive prepared questionnaires. i have no idea what population to use. i have thought of using the residents of our city but its to big. is there a way that we could just choose a random person, lets say 50 random persom. is that possible becase the cities pop. is about 100,000+. and do we need to use anova?
