正确表达This sampling method is widely used in social research.

method 是执行抽样的手段，动作是主动的，所以要用 sampling（抽样的方法）；sampled 表示「被抽样的」，只能修饰被抽到的对象，如 sampled data、sampled students。

易错句子The sampled of 200 students was too small.

正确表达The sample of 200 students was too small.

「样本」是名词 sample；sampled 是形容词或动词过去分词，不能作名词充当主语。这句需要名词，所以用 sample。
