The following are four propositions:  
\\(①\\) From a uniformly moving production line, a quality inspector takes one product every \\(20\\) minutes for a certain indicator test. Such sampling is stratified sampling.  
\\(②\\) The stronger the correlation between two random variables, the closer the absolute value of the correlation coefficient is to \\(1\\).  
\\(③\\) In the regression line \\( \hat{y}=0.2x+12\\), when the explanatory variable \\(x\\) increases by one unit, the forecast variable \\( \hat{y}\\) increases by an average of \\(0.2\\) units.  
\\(④\\) For categorical variables \\(X\\) and \\(Y\\), and their random variable \\(K^{2}\\)'s observed value \\(k\\), the smaller \\(k\\) is, the greater the certainty that "\\(X\\) and \\(Y\\) are related". Among these, the correct propositions are \_\_\_\_\_\_.
