Suntor is a German software developer based in Munich. It engineers, designs, develops and markets CAD $($computer$-$aided design$)$ software for tool and die manufacturers that specialize in the aerospace industry. This application has undergone a significant amount of time in research and development to fine$-$tune it so it will seamlessly integrate with other manufacturing software and to ensure it meets rigorous security standards. On top of internal product testing, the company released a beta version among its partner channels in the U$.$K$.$ and Germany. It designed and compiled a survey for users pertaining to usability and software integration. The integration survey uncovered that $24$ percent of users experienced some form of integration problem in the course of use over a month, while $72$ percent of users found that the application was more user$-$friendly than competing products. Suntor hopes that American private and military organizations will take a keen interest in its product. In the later stages of research, representatives from Suntor travelled to the U$.$S$.$ to participate in a major aerospace and defense symposium. They were able to gather information regarding distribution channels, competitors and American industry statistics relevant to Suntor's CAD software application. In the final phases of its research, Suntor designed research tools to help it better understand the pace of development of tool and die manufacturing in the aerospace industry. It wishes to investigate this area more thoroughly so it will have a more complete understanding of the lifecycle of its product in the American market and the expected frequency of significant upgrades. In addition, it is also investigating what sort of export permits it will be subject to when the software is shipped to clients in the U$.$S$.$ In the survey Suntor used, it asked respondents how many times during the past month they experienced technical difficulties with the product when integrating it with other software programs. The possible responses on the questionnaire were: a$)$ I have not used this program this month; b$)$ once; c$)$ two or three times; and d$)$ more than three times. What type of data would be generated from this question?.
