True or False?
A researcher is interested in studying whether there is a correlation of IQ with health. For this purpose he selected a sample of 261 people and asked them to complete two questionnaires: one for IQ and one for health. After evaluating the questionnaires each person had a total score in these two concepts resulting from the sum of questions in the respective questionnaires. Finally he decided to use the correlation coefficient Spearman's rho to give answer to his question.
