Given the following four statements:  
\\(①\\) When drawing a frequency distribution histogram, the area of each small rectangle equals the group interval of the corresponding groups;  
\\(②\\) In depicting the fitting effect of a regression model, the larger the value of \\(R^{2}\\), the better the fitting effect;  
\\(③\\) Let the random variable \\(ξ\\) follow the normal distribution \\(N(4,2^{2})\\), then \\(P(ξ > 4)= \dfrac {1}{2}\\);  
\\(④\\) For categorical variables \\(X\\) and \\(Y\\), if the observed value \\(k\\) of their statistic \\(K^{2}\\) is smaller, then the probability of making a mistake in judging that "\\(X\\) and \\(Y\\) are related" is smaller;  
Among these, the correct statements are \_\_\_\_\_\_.
