Doing this experiment allowed us to decide whether or not music effected concentration when completing tasks such as completing word search puzzles. The materials used in this experiment included 2 buckets containing an equal number of grey and red poker chips, classical music, three word search puzzles (Puzzle 1, 2, and 3), Puzzle 1 was completed as practice, and two separate rooms referred to as Room A (silence) and Room B (with music). This experiment was a non-blinded test as the subjects were aware of rather they were being tested with or without the use of music. Randomization was implemented with the use of red and grey poker chips. Two buckets were equally mixed with both red and grey poker chips. Students selected a chip from each bucket in order to determine rather they would go to Room A (silence) or Room B (with music) first and rather they would start with Puzzle 2 or Puzzle 3first. Pulling a red chip first meant that you would go to Room A first whereas pulling a grey chip …show more content…

  • Explains that the experiment allowed them to determine whether music effected concentration when completing word search puzzles.
  • Explains that the experiment was a non-blinded test as the subjects were aware of rather they were being tested with or without the use of music.
  • Explains that students completed puzzle 2 or 3 first, depending on which room they were in, while students in room b completed their puzzles accompanied by classical music. the number of words found in each setting was then tallied.
  • Describes the methods used to analyze the data collected including hypothesis testing and 90% confidence intervals.

Students in Room A did their first puzzle in silence while students in Room B completed their puzzles accompanied by classical music. After completing the first puzzle students switched rooms and completed the puzzle they had not yet completed. The number of words found in each setting was then tallied. Methods used to analyze the data collected included Hypothesis Testing and 90% Confidence Intervals. The Hypothesis Test is used to determine whether there is enough evidence in a sample of data to infer that a certain condition is true for the entire population. In our case this the Hypothesis Test would determine rather or not music effects concretion of completing certain tasks as a whole. The Confidence Interval expresses the degree of uncertainty associated with a sample statistic. It also gives a range of values that the mean will fall in this case 90% of the
