What is the main difference between systematic random sampling and stratified random sampling?
What is the main difference between systematic random sampling and stratified random sampling?
- Systematic random sampling involves choosing a random starting point, while stratified random sampling groups the population based on categories. (correct)
- Systematic random sampling eliminates bias, while stratified random sampling increases the likelihood of bias.
- Systematic random sampling focuses on selecting elements from each stratum, while stratified random sampling involves lottery selection.
- Systematic random sampling involves dividing the population into groups, while stratified random sampling considers every kth element.
If a population of 100 students is to be sampled using systematic random sampling with a sample size of 20, what would be the value of q in this scenario?

In systematic random sampling, how can the starting point be determined?
In systematic random sampling, how can the starting point be determined?
- By choosing any arbitrary number as the starting point
- By selecting the smallest number in the population
- Using a lottery method on all population numbers
- By dividing the total number of population members by the desired sample size (correct)
