Master's thesis can use different scales. In research, scales are usually used to collect and measure data of research objects. Different scales may have different scoring systems, depending on the purpose of the scale, the measurement attributes and the requirements of the use field.

In some disciplines, especially in social science and psychology, the general scale is widely accepted. For example, some common scoring systems include 1-5, 1-7 or 1- 10.

However, some factors need to be considered when choosing scale and scoring system. First of all, the choice of scale should match the research question, which is acceptable and reliable in methodology. Secondly, we should choose a suitable scoring system according to the standards and practices in the research field.

In short, different scales can be used with different scoring systems, but the choice of scales and scoring systems should meet the requirements of research purposes and fields.
