According to Cochran's formula, there were 384 Iranians people as a statistical sample for tourists and 384 people were obtained as a sample of foreign tourists’ statistics and were distributed among the statistical population through random sampling method.

According to the findings of the questionnaires, it was found that the behavior pattern of tourists shows that foreign tourists travel a greater distance from Razavi Holy Shrine (65 km) for tourism elements available around Mashhad city. Therefore, their behavioral pattern is scattered. This is while domestic tourists are mostly located around the Holy Shrine and up to a radius of 30 kilometers from the Razavi Shrine, and their behavioral pattern is clustered around the Shrine of Imam Reza (A.S.).
