傳播是訊號的傳送；波，是訊號傳送的具象。 傳播訊息是為了影響他人，傳送訊息途中也有可能會被其他因素干擾，如同波紋在交集時也因為頻率相同或不同而另外產生新的波形。
此設計也利用視錯覺原理 利用不同角度觀看圖形 會有動態波紋產生。
Communication is about sending signals, the WAVE is the concrete of signal. We communicate to interfere others, and the messages might be interfered by some substance. It's just the same as the waves create new forms when they are overlapping.

此設計利用密集的線條產生幾何圖形，並以形狀與顏色（印刷原色CMY）來區分書中的三大分類--
社會調查類：使用方形，陵陵角角代表這個方法的量化特性，有較多嚴謹的規定。
田野觀察類：使用有機不規則形，代表這個方法的質化特性，可彈性隨現象調整作法。
大數據分析類：使用圓形中的內部變化，代表在全球網絡中收集數據的作法。
而基礎教程內容涵蓋此三大類，但內容為入門課程，所以圖形使用CMY分別上色的圖形交疊，交疊處除了顏色相疊的效果，也有波紋相疊的效果。
The pattern uses high density of lines to create an illusion of wave. Since the book has categories of three types of research methods, each of patterns represents a type of research method.
Square stands for quantitative method, which has rigorous rules. Organic shapes stands for qualitative method, which is more flexible when practicing. Circle means collecting big data, which collect datas around the world.
