Summarizing, organizing, simplifying and communicating the nature of a data set in numerical terms. these numerical accounts are intended to describe the data set without inferring causal factors ( what caused the data). Using random sample and university based surveys, we elaborate the first empirically based study of what africans think of their relationships with china. we reach three conclusions. first, african views are not nearly as negative as western media make out, but are variegated and complex.
