| 1. | Under these circumstances, multistage cluster sampling becomes useful.
|
| 2. | The main objective of cluster sampling is to reduce costs by increasing sampling efficiency.
|
| 3. | Cluster sampling is commonly implemented as multistage sampling.
|
| 4. | Although cluster sampling and stratified sampling bear some superficial similarities, they are substantially different.
|
| 5. | If these conditions do not hold, stratified sampling or cluster sampling may be a better choice.
|
| 6. | Cluster sampling is used to estimate high mortalities in cases such as wars, famines and natural disasters.
|
| 7. | Community-based surveys are applied using a modified cluster sampling survey method developed by the World Health Organization.
|
| 8. | This is a complex form of cluster sampling in which two or more levels of units are embedded one in the other.
|
| 9. | In this sense, this technique is similar to cluster sampling, since the choice of the first unit will determine the remainder.
|
| 10. | In stratified sampling, a random sample is drawn from each of the strata, whereas in cluster sampling only the selected clusters are studied.
