Question

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?

1. 400 RANDOMLY CHOSEN EMPLOYEES FROM THE LIST OF ALL EMPLOYEES.
2. ALL 624 FEMALE EMPLOYEES IN THE COMPANY.
3. ALL EMPLOYEES WHO HAVE WORKED IN THE COMPANY FOR 5 YEARS OF MORE.
4. A GROUP WITH ONE MEMBER FROM EACH DEPARTMENT.

Answer 1

1. 400 randomly chosen employees from the list of all employees would provide the most valid generalization as it includes a diverse sample of the entire employee population. This sample would be more representative of the entire company's preferences compared to the other options which may introduce bias based on gender, tenure, or department.
