Is your visual memory stronger than your auditory memory, or vice versa?
PROCEDURE
Write one number sequence on each index card, until you have a deck of about 50 different random sequences. You will use this deck for your experiments.
You will also need a data table for your experiment. It should have a place to record the number of correct answers for each participant, and for each type of memory test.
To test someone's visual memory, show them a card for 30 seconds and time them with a timer. Take back the card and have them recite the alphabet. Then ask them to tell you what the numbers were. Write down how many numbers they got right. This will be their score.
To test someone's auditory memory, read them the sequence of numbers on a different card three times slowly. After you read them the numbers, have them recite the alphabet. Then ask them to tell you what the numbers were. Write down how many numbers they got right. This will be their score.
Calculate the percentage of people who received each score. Do this by first adding the total number of participants for each column, then divide the number of people receiving the score by the total number of participants in your study. Multiply the answer by 100 to get the percentage.
Analyze your data by making a histogram. On the left side of the graph (Y-axis), write a scale for the percentage of people from 0 to 100%. On the bottom of the graph, write a scale for the number of correct responses from 0 to 7. Then using two colors, one for each type of memory, draw your results on the graph.
