These are the correct statements:
- Group #3's results showed a consistent trend: the shorter the string length, the shorter the period.
- According to Group #2's data, the time of the period varied directly with the height of the drop.
Why are these comparisons true or false?
False: All three groups had the same dependent variable.
Different experiments may have different dependent variables based on their objectives. It cannot be assumed that all three groups had the same dependent variable.
False: All three groups had the same independent variable.
The experiments may have different independent variables depending on the experimental setup. It cannot be assumed that all three groups had the same independent variable.
True: Group #3's results showed a consistent trend: the shorter the string length, the shorter the period.
This statement indicates a consistent trend observed in the results of Group #3.
False: Group #1 showed no significant change in the period as they changed the weight of the bob.
This statement suggests that there was no significant change in the period, but it does not provide information about Group #1's actual results.
True: According to Group #2's data, the time of the period varied directly with the height of the drop.
This statement indicates a relationship observed in Group #2's data, where the time of the period varied directly with the height of the drop.
