The CEO of a local tech company wants to estimate the proportion of employees that are pleased with the cleanliness of the break
rooms. She considers two methods of obtaining a sample of 600 employees from the 4,700 employees at the company. Part A: To make the process easier, the CEO considers surveying the first 600 employees who enter a company annual conference center. Identify the type of sampling method proposed and discuss why this sampling method might be biased. (5 points)
Part B: The second method the CEO is contemplating involves using a random number generator app to choose a simple random sample of 600 employees from a list of 4,700 employee names. How could she implement this method? (5 points)
The type of sampling method proposed is a <u>convenience sampling</u> because it's a non-probability sampling method.
<h3>What is convenience sampling?</h3>
Convenience sampling can be defined as a type of non-probability sampling method which involves surveying and selecting representatives that are easily accessible.
The CEO could implement the second sampling method as follows:
Assign a serial number to each employees of the total 4,700 employee names.
Use a random number generator software to obtain 600 random numbers.
The 600 random numbers in Step 2 above forms the desired sample of 600 employees out of 4,700 employees at the company.
