What is the purpose of sampling techniques?
What is the purpose of sampling techniques?
- To generalize about all possible cases or elements
- To ensure collection of data from the entire population
- To increase the amount of data needed to collect by considering only data from a sub-group
- To reduce the amount of data needed to collect by considering only data from a sub-group (correct)
When can sample data be used to generalize about an entire population?
When can sample data be used to generalize about an entire population?
- When the sample size is small and not diverse
- When the sample is selected based on convenience
- When the sample is selected randomly without considering representation
- When the sample is selected carefully and represents the entire population (correct)
Why should one not assume that a census would necessarily provide more useful results than collecting data from a sample?
Why should one not assume that a census would necessarily provide more useful results than collecting data from a sample?
- Because a census always provides biased results
- Because a census is less time-consuming than collecting data from a sample
- Because it is more cost-effective to collect data from a sample
- Because a census may not accurately represent the entire population (correct)
