Question

interpreted with any validity.

1. an experiment was performed to determine how the amount of coffee grounds could affect the taste of

coffee. the same kind of coffee, the same percolator, the same amount and type of water, the same perking
time, and the same electrical sources were used.

independent variable

dependent variable

constants (3)

Explanation:

• Independent variable: The independent variable is the factor that is manipulated in an experiment. Here, the amount of coffee grounds is what's being changed to see its effect, so it's the independent variable.
• Dependent variable: The dependent variable is the factor that is measured or observed to see the effect of the independent variable. The taste of coffee depends on the amount of coffee grounds, so it's the dependent variable.
• Constants: Constants are factors that are kept the same throughout the experiment. From the problem, the same kind of coffee, the same percolator, and the same amount and type of water (we can pick three, these are examples) are kept constant.

Answer:

• Independent variable: Amount of coffee grounds
• Dependent variable: Taste of coffee
• Constants (3): Same kind of coffee, same percolator, same amount and type of water (other valid constants from the list like same perking time, same electrical sources can also be used as part of the three)
