Snowball sampling
Okay kiddo, so imagine you're picking berries in a field. You start with one berry and then you look for more berries nearby. Then you find another berry and look around for more berries near that one. You keep doing this until you've gathered a big bunch of berries.
That's sort of like snowball sampling, except instead of berries, we're looking for people to answer questions or be part of a study. We start with one person we know and ask them to help us find more people to include in our study. Then we ask those people to help us find more people, and so on.
It's called "snowball" sampling because it's like rolling a snowball down a hill - it starts small, but as it picks up more snow along the way, it gets bigger and bigger. In snowball sampling, our sample (or group of people we're studying) starts with just one person, but as we add more people to it, it grows and grows until it's big enough for us to analyze and draw conclusions from.
Does that make sense, kiddo?
