Student researchers at Hope College conducted an experiment to determine whether students memorize material better if they are taking notes on paper using handwriting as opposed to taking notes on a computer. They randomly assigned 20 students to the paper-based note-taking group and 20 students to the computer-based note-taking group. They showed all their subjects a 12-minute video about the sun and they were allowed to take notes in the method they were assigned. After the video was over, the notes were collected, and the students were given a 10-question quiz over information about the sun given in the video. Do students tend to memorize better using hand-written notes? (The results data are in the file NoteTaking.)

Question
Student researchers at Hope College conducted an experiment to determine whether students memorize material better if they are taking notes on paper using handwriting as opposed to taking notes on a computer. They randomly assigned 20 students to the paper-based note-taking group and 20 students to the computer-based note-taking group. They showed all their subjects a 12-minute video about the sun and they were allowed to take notes in the method they were assigned. After the video was over, the notes were collected, and the students were given a 10-question quiz over information about the sun given in the video. Do students tend to memorize better using hand-written notes? (The results data are in the file NoteTaking.)
Transcribed Image Text:(a) Put the data in the Multiple Means applet to create a null distribution and from it calculate a standardized
statistic. Round answer to 2 decimal places, e.g. 0.29.
Standardized statistic =
-1.27
eTextbook and Media
Your answer is incorrect.
(b) Explain what your statistic from part (a) means in context.
° The answer to part (a) represents the number of standard deviations that 1.425 (difference between the
average quiz scores) is below the mean of the null distribution.
The answer to part (a) represents the number of standard deviations that 1.425 (difference between the
average quiz scores) is above the mean of the null distribution.
The answer to part (a) represents the number of standard deviations that the difference between the
average quiz scores (taking notes on paper - taking notes on computer) is below 1.425.
The answer to part (a) represents the number of standard deviations that the difference between the
average quiz scores (taking notes on paper - taking notes on computer) is above 1.425.

X Your answer is incorrect.
(c) Based on your statistic, is there strong evidence of a difference in the quiz scores between the two types of
note-taking groups? Explain how you know.
Yes, there is strong evidence of a difference in the quiz scores between the two types of note-taking
groups because the standardized statistic is close to 0.
Yes, there is strong evidence of a difference in the mean quiz scores between the two types of note-
taking groups because the standardized statistic is more than 2.
No, there is not strong evidence of a difference in the mean quiz scores between the two types of note-
taking groups because the standardized statistic is close to 0.
No, there is not strong evidence of a difference in the quiz scores between the two types of note-taking
groups because the standardized statistic is more than 2.
