Bonjour ,

quelqu'un peut me dire comment ils ont calculé cet average Index ?

The feedback from questionnaires was based on the respondents' perception of four types of heritage values,namely aesthetic, historic, scientific and social. They were asked about their agreement with Likert Scale ranging
from 1 to 5 from descending order: 5 represents - Strongly Agree; 4- Agree; 3- Neither Agree or Disagree; 2-
Disagree; and 1- Strongly Disagree. The data collected then were studied and analyzed using Frequency Analysis
and Average Index. Frequency Analysis used depends on the percentage of respondents giving the same answer and
will measure the degree of agreement on a certain statement. Average Index was used to determine the level of
agreeness on heritage values criteria/ statement. The classification of the rating scales is as follows.

Table 1. Average Index used to determine the level of agreement on heritage values criteria/ statement.

Description Rating Scale
Strongly Disagree (SD) 1.00 < Average Index (I) < 1.50
Disagree (D) 1.50 ≤ Average Index (I) < 2.50
Neither Agree or Disagree (NA/D) 2.50 ≤ Average Index (I) < 3.50
Agree (A) 3.50 ≤ Average Index (I) < 4.50
Strongly Agree (SA) 4.50 ≤ Average Index (I) < 5.00
