1. Which of the following best describes a simple random sample?
Every nth member of the population is selected.
The population is divided into strata, and a random sample is taken from each stratum.
Every member of the population has an equal chance of being selected.
The sample is chosen based on convenience.
2. A school wants to survey its students about their favorite lunch options. They decide to survey every 10th student who enters the cafeteria. What type of sampling method is this?
Simple Random Sampling
Stratified Sampling
Systematic Sampling
Convenience Sampling
3. A is a subset of individuals selected from a larger population.
4. In sampling, the population is divided into homogeneous subgroups, and then a simple random sample is drawn from each subgroup.
5. bias occurs when some members of the population are less likely to be chosen or cannot be chosen in a sample.
6. A non-random sample is always preferred over a random sample for statistical inference.
True
False
7. Random sampling helps to ensure that a sample is representative of the population.
True
False
8. Explain the difference between a population and a sample in the context of statistics.
9. Describe a scenario where stratified random sampling would be more appropriate than simple random sampling.
