Suppose we have 4 series of observations, and we want to check whether some datas are from a normal distribution. We made 4 QQ plots to check the normality. Which of plots is most probable referring to a normal distribution? Normal Q-Q plot (A) Normal Q-Q plot (B) Sample Quantiles Sample Quantiles 0.0 0.2 0.4 0.6 0.8 1.0 0 2 =1 2 Theoretical Quantiles Theoretical Quantiles Normal Q-Q plot (C) Normal Q-Q plot (D) 2 Sample Quantiles Sample Quantiles T 0 2 -1 2 Theoretical Quantiles Theoretical Quantiles O B OD OA OC
