In the following paragraph, I am trying to say data collection has been performed using certain questionnaires, and in the end of the paragraph, I want to say the distribution of those questionnaires has been based on simple random sampling. Is the way I add the explanatory sentence to the end of the paragraph (in bold) correct?
Collecting the information related to the study’s variables was done using Goldman’s standard questionnaire, incorporating 33 questions for measuring the variable of emotional intelligence and its 5 dimensions (self-awareness, self-adjustment, motivation, empathy, and social skills), and the questionnaire of Sherer et al., for measuring the variable of self-efficacy, incorporating 17 questions, with the questionnaires being distributed among the members of the statistical population based on simple random sampling.
