Question

Identify the sampling method used in each scenario. 1) You want to sample 100 employees of Company X. You assign a number to every employee in the company database from 1 to 1000, and use a random number generator to select 100 numbers. 2) All employees of the company are listed in alphabetical order. From the first 10 numbers, you randomly select a starting point: number 6. From number 6 onwards, every 10th person on the list is selected (6, 16, 26, 36, and so on), and you end up with a sample of 100 people. 3)The company has offices in 10 cities across the country (all with roughly the same number of employees in similar roles). You don’t have the capacity to travel to every office to collect your data, so you use random sampling to select 3 offices and survey everyone at those 3 locations. 4)The company has 800 female employees and 200 male employees. You want to ensure that the sample reflects the gender balance of the company, so you sort the population into two strata based on gender. Then you use random sampling on each group, selecting 80 women and 20 men, which gives you a representative sample of 100 people. 5) You want to select a sample of employees of Company X. One day at lunch you poll everyone in the company's cafeteria. A. Convenience sampling B. Simple Random Sample C. Stratified Sampling D. Cluster sampling E. Systematic Random Sampling
