Descriptive-Correlational Survey: Study Habits and Academic Performance
Research information
Statement of the problem
This study describes the study habits of college students and determines whether those habits are related to their academic performance.
Objectives
- To describe the profile of the respondents in terms of sex and year_level.
- To describe the study habits of the respondents in terms of sets_a_study_schedule, takes_organized_notes, reviews_lessons_daily, studies_in_a_quiet_place, and avoids_distractions.
- To determine the relationship between study_habits_score and general_weighted_average.
- To determine whether general_weighted_average differs between the sex groups.

Overall weighted mean = 3.73, 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 statistically significant (p = 0.0000 < 0.05).
Spearman Rank Correlation was used instead of the Pearson Correlation because the latter's assumption(s) were not met (Normality of study_habits_score (Shapiro-Wilk)).
