Tia wants to find out how many people would support a new dog park in her community. She asks the first 3 people she sees walking a dog on her block, would you want a new dog park in town? How can she redesign her survey so it is not biased

Tia should Include random people not just dog owners in her community

Step-by-step explanation:

Tia wants to find out how many people in her community would support a new dog park.

So she asks first 3 people she sees walking a dog on her block whether they want a new dog park in town.

Now this would be clearly a biased survey because she is surveying only dog owners who are walking their dogs on her block.

In order to make it unbiased she should expand the population for this survey and should include random people in her community not just people who own dogs.
