Does my interpretation below on the charts make sense, and am I missing anything?
Interpretation:
For the 50 participants that answered the questions on amount of tv watched per week and current grade point average, the mean for amount of tv watched per week was 11.98, with a standard deviation of 6.096, and the mean for student's current grade point average was 3.172, with a standard deviation of .3907 (Morgan et al., 2020). The Pearson correlation is reported as rs (48) (N-2 for r) = -0.253, p = .050; with the number of participants being 50 (Morgan et al., 2020). The Spearman correlation is reported as rs (48) (N-2 for r) = -0.279, and while this rho is slightly more negative than the Pearsons rho, they both have a similar significance level of .076 and .050 (Morgan et al, 2020). In the scatterplot the linear line (0.064) starts in upper left corner and finishes in the bottom right corner, demonstrating a negative linear relationship, while the two variables have a strong negative correlation, showing that students that spend more time watching tv have a lower grade point average, and those with a lower grade point average generally watch more tv (Morgan et al., 2020).
