i using weka internship have little knowledge data mining. so, maybe knows how can apply following results on data-sets data cluster ? method use compute distances between attributes , mean value of each cluster classify them nearest value. method rough me .

i think no-one can answer this. tips off top of head.
you have used em clustering algorithm, see animated gif on wikipedia page. weka's documentation synopsis:
"em assigns probability distribution each instance indicates probability of belonging each of clusters. "
is complex output want? selects number of clusters (unless constrain number).
in weka 3.7 can use unsupervised attribute filter "clustermembership" in preprocess dialog replace dataset result of cluster assignments. need select 1 reference attribute, though. default selects last one. creates hard-to -interpret output.
