question 1 1 pts
the purpose of a control in an experiment is
○ give direction
● to have a standard, baseline
○ to conclude with all your data
○ know where you start the experiment

Explanation:

In a scientific experiment, a control group serves as a standard or baseline for comparison. It helps to determine if the independent variable has an effect by providing a group that is not exposed to the variable being tested. The option "to have a standard, baseline" correctly describes this purpose. "Give direction" is incorrect as controls don't direct the experiment. "To conclude with all your data" is about data analysis, not the control's purpose. "Know where you start the experiment" is not the role of a control.

Answer:

The correct option is the one with "to have a standard, baseline" (the second option in the list of choices for Question 1).
