What is the first step to the scientific method?

• making a hypothesis

• asking a quesion/defining the problem

• analyzing the data to form a conclusion

• creating a graph based on the data in the data table

A company wants to test a new dog food that is supposed to help overweight dogs lose weight. 50 dogs are chosen to get the new food, and 50 more continue their normal diets. After one month, the dogs are checked to see if they lost any weight. What is the independent variable in this scenario?
