Active study strategies can significantly impact how well information is retained. A psychologist investigated this by assessing the effectiveness of different study techniques. One group of six participants studied a text by taking handwritten notes, while a different group of six participants studied the text using only highlighters. All participants then completed a factual recall test scored out of 25. The raw results and ranks are shown in the table below.
