What are some types of research instruments?

Assuming you are planning to measure the process, especially when your research type is qualitative, the watch list is preferred. Measuring human skills also uses observation

If you want to measure cognitive variables such as student learning outcomes, the test is appropriate. Test types are multiple selection, true and false, matching etc.

The Inkeles scale is more comfortable if the variables are ability or intelligence, such as employee cognitive abilities and student natural intelligence.

If you want to measure unrecognized variables like employee motivation, use the motivation scale of 5-4-3-2-1 (always, often rarely, rarely, infrequently, rarely Never desirable)

If you want to measure your attitude, the Likert scale is suitable for using classification such as strong consent, consent, hold, disagree, strongly disagree.

However, if you assume that all respondents are illiterate, public or very close interviews are appropriate. Thank you

What is the validity? Effectiveness refers to the extent to which the tool measures its intent and how important the "things" measured by the tool are important. Why is this important? If the type is real (or the idea of ​​accurately reflecting the real world) it should be able to understand and predict people's behavior to some extent using that type. Types should help us to usefully distinguish different people's values, attitudes, and behaviors. Essentially, the question of validity is to ask the question "Is this kind true?" Chapter 9 of the Handbook (3 rd edition) details the research conducted to demonstrate the effectiveness of MBTI® instruments. This chapter summarizes a lot of data.

The type of financial product varies depending on the stage of development. Current research classifies the type and frequency of use of equipment, but the question of which kind gives better results remains unsolved. In the future survey, it is necessary to consider not only the type of equipment but also the type of PhVC in order to confirm whether the difference can explain the result of performance.
