The descriptive statistics of the questionnaire responses provide a general overview of participants’ attitudes toward the topic. The mean score across most items ranges from 3.8 to 4.2 on a 5-point Likert scale, indicating a generally positive perception among respondents. The median values are mostly 4, and the mode is also frequently 4, which suggests that the majority of participants selected “agree” for many statements.

The central tendency measures (mean, median, and mode) are relatively consistent, indicating that the data is fairly symmetrical and that responses are clustered around the higher end of the scale. This consistency suggests that participants share similar views, with little variation in their overall attitudes.

One of the most surprising findings is that a few items show a noticeably lower mean (around 3.2–3.4), despite the overall positive trend. This may indicate areas where participants are more uncertain or divided in their opinions. These items could reflect more complex or controversial aspects of the topic.

Regarding variability, the standard deviation (SD) for most items falls between 0.6 and 0.9, suggesting moderate dispersion. This indicates that while most responses cluster around the mean, there is still some variation in how participants perceive certain issues. A few items have higher SD values (above 1.0), which may suggest disagreement or differing experiences among respondents.

There is no strong evidence of extreme outliers, as the Likert-scale format limits the range of responses. However, slight skewness can be observed in some items where the mean is slightly lower than the median, indicating a minor negative skew (a few lower scores pulling the mean down). Overall, the data distribution appears relatively balanced, with a slight tendency toward positive responses.

In conclusion, the descriptive statistics suggest that the sample generally holds favorable views, with some variability in specific areas. These patterns highlight both consensus and points of divergence, which could be explored further in subsequent analysis.
