1. a portion of a large group -> sample

the sample is the part that you select from a population to analyze.

2. choosing a sample so that every member has an equal chance of being chosen -> random sample


in a random sample any member of the group has the same probabilities to be selected.


3. choosing a sample from people who are under 15 years old -> biased sample

when you select based on a characteristic of the group you are running a biased sampling.

4. using the responses of a small group to make conclusions about the large group. -> estimating from a sample

statistics searches to infere information about a large group using the responses from a sample
