Literacy rate is a reflection of the educational facilities and quality of education available in a country, and mass communication plays a large part in the educational process. In an effort to relate the literacy rate of a country to various mass communication factors, a researcher has proposed to relate literacy rate (y) to the following variables: number of daily newspaper copies (per 1000 population)(x1), number of radios (per 1000 population)(x2), and number of TV sets (per 1000 population)(x3). Table 3 shows the data for a sample of 10 countries.
