question 18
a city council has requested a household survey be conducted in a suburban area of their city. the area is broken into many distinct and unique neighborhoods, some including large homes, some with only apartments, and others a diverse mixture of housing structures. which approach would likely be the least effective?
simple random sampling
stratified sampling
cluster sampling

Explanation:

The area has distinct neighborhoods with different housing - types. Stratified sampling can be used to divide by housing - type strata, and cluster sampling can group by neighborhoods. Simple random sampling may not adequately represent the different housing structures in the area as it does not account for the existing heterogeneity.

Answer:

Simple random sampling
