Question

a company redesigned its website. it wants to collect data to see if it is user friendly. which would be the best way to collect the data?
experiment
simulation
observational study
census
sample survey

Explanation:

Step1: Analyze each data - collection method

• Experiment: Involves manipulating variables. Not suitable here as we just want user - friendliness feedback.
• Simulation: Imitates a real - world process. Not relevant for getting user opinions.
• Observational study: Just observes without intervention. May not capture user feelings.
• Census: Surveying the entire population. Costly and time - consuming for a website.
• Sample survey: Selects a representative subset of users. Can efficiently gather user - friendliness data.

Answer:

sample survey
