Question

In a systematic sample a random starting point is chosen, and
Multiple Choice
Each item in the population has a chance of being selected more than once
The population is divided into groups and then samples are drawn from these groups
Each item in a list has a 50% chance of being selected
Every kth item thereafter is selected for the sample

Answer 1

In Systematic sampling, samples are selected from population by selecting a random starting point. However, the interval is periodic i.e. interval is obtained by dividing population size by total sample size that we are going to consider. Because of it, every kth item is selected for the sample (Here k will be the ratio of population size to sample size)

Thus,

correct answer is -

In a systematic sample a random starting point is chosen, and

-The population is divided into groups and then samples are drawn from these groups

-Every kth item thereafter is selected for the sample
