Step-by-step explanation:
Answer: stratified sampling and judgement sampling
Step-by-step explanation:
Stratified sampling is a probability method that is superior to random sampling because it reduces sampling error. A stratum is a subset of the population that share at least one common characteristic.
While
Judgment sampling is a nonprobability method. The researcher chooses the sample based on judgment. This is usually and extension of convenience sampling. For example, a researcher may decide to draw the entire sample from one "representative" city, even though the population includes all cities. When using this method, the researcher must be confident that the chosen sample is truly representative of the entire population.
Answer: Option(c) is correct.
Step-by-step explanation:
Data engineering is a set of guidelines and approaches that characterize the kind of information gathered and how it is put away and utilized.
The Data engineering includes the means, for example, gathering of data, storage of information in the databases and access the information at whatever point required.
So,data engineering refers to information storage, database plan and information structures.
Consequently Data quality isn't clarified in Data engineering.
