the education ministry is interested in determining the level of education of unmarried girls in the country .how would you organise a survey for this purpose?

Education ministry can avail demographic data from census of India and figure out the respective households in which unmarried girls reside. After getting to know their residences, they can collect the data on their education level by direct interaction with them or by telephonic interaction.

Also, the education ministry can study the facts such as what number of girls went to college for higher education after schools by collecting data from academic institutions and classify the girls on the basis of different levels of their education accordingly.
