Who has better digit memory, males or females?

The purpose of my investigation is to determine if males or females have better digit memory. I think this is important to know because if I wanted to remember an important number that I forgot, I would know who to ask- a male or a female.

I hypothesize that the average male has better digit memory than females. I believe this because more males are in mathematic fields. So I believe more males will memorize the digits.

Manipulated - Males or Females Responding - Number of Digits Recalled Constants - Number of Males and Females, Numbers on List, Same Amount of Time, 2 Males 2 Females, Per Trial, Same Procedure.

1. Gather materials 2. Create a list of twenty 3 - digit numbers. 3. Make 20 copies of the list. 4. Give 1 copy to a female tester, face – down. 5. Set the timer for 1 minute, instruct tester to flip paper over. 6. Give the tester 1 minute to memorize the digits. 7. After the 1 minute is over, instruct tester to flip over the paper. 8. Ask the, tester to write down as many numbers as possible in 30 seconds. 9. Repeat steps with 1 more female and 2 males 10. Repeat steps 4 – 9 for 4 more trials. 11. Calculate the Average number of digits recalled for. 12. Calculate the number of digits recalled for males.

My hypothesis was incorrect. Females have a better digit memory than males. The average of digits recalled for males is 2.7. The average of digits recalled for females is 2.8. Now that I know that females are better at remembering 3- digit numbers, I would like to try lower digit numbers and see if males are better at remembering low digit numbers.
