| 7896861440 | Sample Survey | Selects a sample from a population. | 0 | |
| 7896866894 | Random Sampling | Any method that uses chance to select a sample from a population. | 1 | |
| 7896873659 | Simple Random Sample (SRS) | A method that gives every group of a certain size (n) an equal chance of being selected. | 2 | |
| 7896881987 | Stratified Random Sample | A method that first separates the population into groups of similar characteristics then takes a SRS from each of those groups. | 3 | |
| 7896891206 | Strata | Groups of individuals that all have a common characteristic or trait. | 4 | |
| 7896896767 | Cluster Sample | A method of random selection where diverse groups (mini-populations) are numbered and then selected. Each member of the group(s) chosen are sampled. | 5 | |
| 7896914424 | Cluster | A grouping within a population that is diverse (mini-populations). | 6 | |
| 7896927805 | Bias | Systematically favoring an outcome. | 7 | |
| 7896930518 | Voluntary Response Sample | A method of sampling in which the respondents choose themselves. This is a bad sampling technique that is not random and should be avoided as it is prone to bias. | 8 | |
| 7896943531 | Convenience Sample | A method of sampling in which individuals that are easy to access or close by are chosen. This is a bad sampling technique that is not random and should be avoided as it is prone to bias. | 9 | |
| 7896969689 | Sampling Errors | Errors that come from the act of choosing the sample itself. Undercoverage is a common example of this. | 10 | |
| 7896977288 | Undercoverage | A sampling error that occurs when entire groups of the population are left out of the sample. | 11 | |
| 7896986378 | Random Sampling Error | A type of sampling error that occurs through the chance process involved in taking a sample. SRS can sometime produce these when they create samples that over represent some individuals by a large degree. | 12 | |
| 7897002563 | Sampling Frame | The list of individuals in the population that we are actually sampling from. | 13 | |
| 7897013308 | Nonsampling Error | Errors that have nothing to do with the method of sampling. Can be present even in a census (collection of entire population data). | 14 | |
| 7897028267 | Nonresponse | The single biggest problem (type of nonsampling error) that occurs in sample surveys. This is when individuals chosen/contacted for a sample refuse to answer. | 15 | |
| 7897046977 | Response Bias | Incorrect answers from respondents of a survey. Often intentional because they are aware they are being observed or recorded. | 16 | |
| 7897058134 | Wording Bias | This is when the way a prompt is presented causes answers to shift toward an outcome. | 17 |
