“…Previous research has, however, demonstrated that pupil attitudes towards religion are related to a number of other variables. These variables are sex and age (Garrity, 1966;Povall, 1971), intelligence (Hyde, 1959), religious behaviour (Johnson, 1966), parental religious behaviour (Greer, 1971), socio-economic background (Jones, 1962), the geographical location of the school (Alves, 1968), and the co-educational or single sex status of the school (Wright and Cox, 1967). Since these variables may contaminate the influence of the school on pupil attitudes they must be taken into consideration in the research design.…”
