statisticsnormal-distribution
Based on this QQ-plot, does this looks approximately normal?
based on the attached QQ-plot, can I say that the distribution is approximately normal? The results for Shapiro-Wilk test is p-value = 0.1334 but the sample size is small (only 12 as they are observations for each month) so I am not sure if its suitable to use the results from Shapiro test.
Solution
No, it is not. As the line has a different slope by the line of y = x, it means that this distribution has a different skewness than the normal distribution.
