Descriptive-Comparative Survey: Student Satisfaction Across Year Levels
Research information
Statement of the problem
This study describes student satisfaction with campus services and determines whether satisfaction differs across the respondents' profile.
Objectives
- To describe the profile of the respondents in terms of sex and year_level.
- To describe the satisfaction of the respondents in terms of facilities_are_adequate, staff_are_responsive, services_are_timely, and information_is_clear.
- To determine whether satisfaction_score differs across year_level.
- To determine whether satisfaction_score differs between the sex groups.

Overall weighted mean = 3.79, interpreted as “Agree”.
The interpretation bands assume a 1-5 scale. State the instrument's scale if it differs. · Weighted means treat the rating scale as equal-interval, which is the standard convention for summarising Likert items but is a descriptive summary, not a statistical test. The median is reported beside each mean as the measure that does not require that assumption.

The result is not statistically significant (p = 0.8540 >= 0.05).
Mann-Whitney U Test was used instead of the Independent-Samples t-Test because the latter's assumption(s) were not met (Normality of group 'Female' (Shapiro-Wilk), Normality of group 'Male' (Shapiro-Wilk)).
