Below are 100 daily observations of wastewater influent and effluent lead Pb concentration measured as Ug L in wastewater. State your expectation for the relation between influent and effluent and then plot the data to see whether your ideas need modification.

Smoothing is drawing a smooth curve through data in order to eliminate the roughness scatter that blurs the fundamental underlying pattern. It sharpens our focus by unhooking our eye from the irregularities. Smoothing can be thought of as a decomposition of the data. In curve fitting this decomposition has the general relation data fit residuals. In smoothing the analogous expression is data smooth rough. Because the smooth is intended to be smooth as the fit is smooth in curve fitting we usually show its points connected. Similarly we show the rough or residuals as separated points if we show them at all. We may choose to show only those rough residual points that stand out markedly from the smooth Tukey 1977 . .
