not following the scientific method
performing one trial
controlling fewer variables

Explanation:

• Not following the scientific method would reduce validity.
• Performing one trial may lead to inaccurate results due to chance.
• Controlling fewer variables makes it harder to isolate the effect of the independent variable.
• Performing multiple trials helps to average out random errors and increases the reliability and validity of the experiment.

Answer:

Performing multiple trials.
