The data on the effective qualifications of teachers in medical sciences: An application of combined fuzzy AHP and fuzzy TOPSIS methods

In this data article, hybrid fuzzy Analytic Hierarchy Process (AHP) and fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) were used to prioritize the effective qualifications of teachers of medical courses at university from the viewpoint of students of allied medicine school in Tehran University of Medical Sciences in 2013–2014. To obtain data, 200 students of allied medicine school of Tehran University of Medical Sciences were selected using random sampling method, and surveyed according to Cochran׳s formula. Data collection tools were two research-based questionnaires divided to technical, professional and individual parts. Content validity was approved by the experts. Reliability was confirmed by calculating the Cronbach׳s alpha (α=0, 85) in order to measure the degree of internal cohesion.

Data collection tools were two research-based questionnaires divided to technical, professional and individual parts. Content validity was approved by the experts. Reliability was confirmed by calculating the Cronbach's alpha (α ¼0, 85) in order to measure the degree of internal cohesion. &

Value of the data
There has not been a complete study about the classification of effective qualifications of teachers [1]. The data in this article provides such information.
This data can be useful teachers of medical courses at university to enhance their ability. This data can be useful for medical educational programs to enhance their quality.

Data
The demographic data of scholars is shown in Table 1. Table 2 shows the data from calculating the weights of other criteria. The positive and negative ideal points were also determined regarding the equations 9 and 10 and the distance of each index from the ideal points was calculated. By considering the calculated distances and finally criterion of similarity of ranking the main indexes for the given case has been measured. The data have been shown in Table 3. Accordingly, these three main indexes have been ranked by AHP integrated algorithm and fuzzy TOPSIS and the ability to evaluate the students has been determined as the most and appearance as the least important factors. Table 1 Demographic data of scholars.

Experimental design, materials, and methods
To obtain this data, samples were included the medical students of Tehran University of Medical Sciences. Based on De Morgan model, 200 students were determined from 420 students during 2013-2014. We explained our objectives to the students, and ensured them that their data will be used anonymously. For ranking the three indexes of technical, professional and personal qualifications in teachers of medical course from the point of view of students, six criteria were considered. The weights of six criteria were determined by AHP method and then three main indexes were ranked by using these weights and fuzzy TOPSIS. For this purpose, in the first stage, based on the decision tree shown in Table 4, a questionnaire including pair comparison was designed to determine the weights of criteria and handed out among the participants. According to Table 3, the mentioned questionnaire includes 17 indexes for effective teaching in three dimensions of technical (5 indexes), professional (5 indexes) and personal qualifications (7 indexes). Validity of this questionnaire was approved by interviewing with experts and professors and its reliability was approved by Cronbach alpha (α ¼ 0.85) for measuring the degree of internal cohesion of questionnaires. The internal cohesion means the questions which are considered for measuring a common concept should have practically similar points.
After completing the questionnaires, using the formulae of MATLAB, first the rate of inconsistency of comparison matrix was calculated and the answers which their inconsistency rate was more than 0.1 were excluded. By means of geometric means formula, the matrix of individuals' comments was integrated into one matrix. In next stage, the final matrix entered to the software and final weight for each criterion was calculated by Buckley [2] that is presented in Table 5.
In the next step, the fuzzy TOPSIS for ranking the main indexes was used. For this purpose, the participants were asked to assess the importance of each option by using linguistic variables presented in Table 6 and fuzzy numbers corresponding to them.   Table 6 Linguistic variable used to rank the options.
