The results of the experiment indicate that recall is more accurate and easier when a set of numbers are smaller chunks as opposed to larger chunks. The mean recall of the control group was 8.81 compared to a mean of 4.69 in the experimental group. These findings are consistent with David W. Fendrich and Raina Arengo’s (2003) findings which indicate that the length of a string of numbers does affect the ability to recall. Although the participants found it significantly harder to remember the numbers in larger chunks, the results do indicate that it is difficult for participants to recall chunks when the number of chunks surpass the “Magical Number Seven” plus or minus two based on Miller’s (1956) findings. This supports the hypothesis of this experiment and confirms the findings of the original experiment. However, the results may have occurred because of the overwhelming amount of numbers in the experimental group as opposed to the minor amount of numbers in the control. This experiment was conducted under laboratory conditions which contains many values and limitations. Conducting a laboratory experiment allows the experimenter to freely manipulate the independent variable which demonstrates cause and effect relationships. Lab experiments allow for an increased control of extraneous variables and accurate measurement of findings. The standardized procedures also allow for replication to occur. However, total control of variable is impossible. The only participant
