A large company wants to find out what team-building activity its employees prefer. Which of the following samples can give the most valid generalization?
a group with one member from each department
all employees who have worked in the company for 5 years or more
400 randomly chosen employees from the list of all employees
all 624 female employees in the company
C. 400 randomly chosen employees from the list of all employees. This sample is diverse and representative of the entire company, providing a good sample size to draw conclusions from. The other samples may not be diverse or representative enough to provide a valid generalization.
The sample that can give the most valid generalization in the given scenario would be 400 randomly chosen employees from the list of all employees.
By selecting a random sample, the company ensures that the chosen employees are representative of the entire employee population. This reduces the potential for bias and allows for a more accurate generalization to be made about the preferences of the employees as a whole regarding team-building activities.
