To determine the public opinion on whether hockey is too dangerous, the least biased and most useful sample would be group of shoppers at a shopping mall.
This sample includes a broader and more diverse range of individuals who may or may not have an interest in hockey, reducing the influence of pre-existing biases from hockey or sports fans. In contrast, fans at a hockey game and sportscasters are likely to have more positive views on hockey, and fans at a football game may not provide relevant perspectives on hockey specifically.
