We wish to test the hypothesis that music improves leaning. We compare test scores of students who study to music with those who study in silence. Which of the following is an extraneous variable in the experiment? A. the amount of time allowed for the studying B. Any of them is an extraneous variable C. the students test scores D. the presence or absence of the music

The statement that "there will be no significant difference in the performance of students who learn with music and student who do not learn with music" is an example of a/an A. null hypothesis B. alternative hypothesis C. basic research D. applied research

A researcher uses an experimental design to study the effect of music on memory. In this experiment, the Independent Variable is:a. musicb. memoryc. both music and memoryd. neither music nor memory

A study was conducted to explore the possibility of a music treatment effect on someone's ability to estimate time. One version of the study involved 115 university students. Each student was led into a dark room, and asked to press a button exactly three minutes after a signal was given. The time that actually passed from the signal to the pushing of the button was recorded in minutes. The university students were allocated to one of the two groups based on their weight. One group listened to jazz music during the study, while the other group did not. The researchers found a difference of 0.18 minutes between the mean of the times recorded for each group, with the group that listened to jazz music having the higher mean. The tail proportion from a randomisation test carried out with the data from the study was 115/1000. Use the information above to answer the following questions. In some cases, you will need to copy and paste words exactly as they appear above. Who were the participants in this study? student How many participants were used for this study? What was the treatment effect explored? treatment effect What were the units used to measure the response variable? Write the tail proportion as a percentage (rounded to one decimal place e.g. 12.5 or 25.0): 11.5 % Is the observed difference compatible with the null model? (enter yes or no) Is the observed difference unusual when compared to the 'just chance' distribution? (enter yes or no) Was randomisation used in the design of the study? (enter yes or no

Which of the following statements is INCORRECT? __ (2 points)Group of answer choicesThe University of California professor Gordon Shaw who conducted a study on a 2nd grade class in music discovered that the 2nd graders performed on a 6th grade level in math.Frances Rauscher states that children that take music, their SAT scores are more likely to be lower than students that haven’t been taken a music class.Music study enhances their grades in math/reading.Scientific evidence on the effort of music shows that children express themselves through music and that music is beneficial to the children in their academics.
