An ethnographic group is a group of people who share a common culture and way of life. Just like how you and your friends might have your own secret handshake or inside jokes, different groups of people have their own unique ways of doing things too. For example, some groups might have their own language, certain foods they like to eat, or special traditions they follow.
People in an ethnographic group often have a lot in common with each other and they might feel a strong sense of belonging to the group. Even though we are all different in our own ways, it's important to respect and appreciate other people's cultures and ways of life.
