We're interested in whether there's a relationship between the Visual and Kinesthetic learning styles of Biology students. We had 36 students in the classroom. We know that the standard deviation of Visual scores for the students in our classroom is 3.814611, the standard deviation for the Kinesthetic scores is 2.941445, and the covariance between these two variables is 5.269162. Calculate the Pearson product- moment correlation coefficient for these two variables, based on these numbers: 0.4696

Question 1 5 pts We're interested in whether Biology students have higher Visual relative to Kinesthetic learning styles. We've decided to use a paired t-test to investigate the question, based on our classroom as our sample. What assumptions do we have to make to use this method? our sample is an unbiased representative sample of the population both the Visual...

A researcher wanted to see if live reggae music improved students’ math test scores. He selected a sample of 61 students from his university and gave them a math test. The students then studied for two and a half hours while an acoustic reggae band played quietly. The students then took another math test of the same difficulty. The researcher’s variable was the change in test score for each student — a positive change meant the student did better, while...
