Explanation:

In a simple pendulum experiment, the independent variable is what's manipulated (length), and the dependent variable is what's measured (period). A scatter plot with length on the x - axis (independent) and period on the y - axis (dependent) is appropriate. The notebook entry here correctly identifies length as independent and period as dependent, and the plot shows period vs length, which is the right way to represent the relationship.

Answer:

The notebook entry (Choice 1) is correct. The independent variable is Length (manipulated), the dependent variable is Period (measured), and the plot (Period vs Length) is the best choice as it shows the relationship between the two variables.
