Music has become a growing industry throughout history. People want to hear it during any occasion possible. Many students tend to use music for studying. In this paper, the researcher will analyze the different types of music – classical and dubstep –and their correlation with memorization and recall. The researcher will gather a group of 30 students from Miramar High School. The 30 students will then be separated into three groups – the constant group and two experimental groups—into five students. The constant group will be asked to memorize a list of 10 words for a minute. There will be no music playing during the memorization process and recall. One experimental group will be asked to memorize and recall the list of words while the song “Nocturnes, Op: 6: No. 2 in E-Flat major” (classical) is playing in the background. The second experimental group will be asked to do the same except they will be listening to “Big Boss” by Doctor P (Dubstep). After the researcher conducts the experiments, she will analyze the results collected, and compare the correlation between the different types of music’s influence on memorization and recall. The aim of this research is to find the correlation between listening to music during learning and recall. Null Hypothesis: The correlation between classical and dubstep music and recall are independent. Alternative Hypothesis: The correlation between classical and dubstep music and recall are not independent.

The data collected is from the sample of 30 students. Each group had a set of 5 students. The word list represents the words the students from all the groups had to memorize and recall during the experiment. The three main groups represent the different type of testing environment the students were placed in. From the words collected, seven words were constantly recalled through the different experiment groups. These words are date, mall, sand, pink, iris, hail, and gray. The next words that were recalled frequently were fate, tall, micee, and stab. The words café, beds, and ears were barely recalled throughout all three experiments.

This table shows the descriptive statistic of the constant group. They memorized and recalled the words without music. The mean of the students who memorized and recalled words without music is 3.071429. Median of words recalled is 3.5 per student. Most students recalled about four words each when placed in an environment without music.
