(i) High levels of correlation do not prove that there is cause and effect. (ii) A correlation coefficient of 0.73 would generally be regarded as indicating a strong linear relationship between the variables. (iii) The coefficient of determination provides this information and is given by squaring the correlation coefficient, resulting in 53% in this case. (iv) The coefficient of determination provides this information and not the correlation coefficient. Remember that you must square the correlation coefficient in order to obtain the coefficient of determination.Statements (ii) and (iii) are relevant and the correct answer is therefore C.
