01 · THE QUESTION
Is student depression about who they are, or what they face?
The project set out to find the root causes behind a high depression rate and turn them into actions a university could take.
- Q1How strongly do academic pressure and financial stress relate to depression?
- Q2What role do sleep and other lifestyle signs play?
- Q3How strong a warning sign is a history of suicidal thoughts?
- Q4Does family history matter as much as current circumstances?
02 · THE DATA & CLEANING
From raw files to clean tables
One table of 27,901 students with academic pressure, financial stress, sleep duration, study habits, family history and a depression flag.
- a.Financial stress was stored as text with "?" values; it was cleaned, then converted to whole numbers.
- b.Sleep duration had stray quote marks; it was cleaned into a Sleep Group column.
- c.A Sleep Rank (1 to 4) was added so sleep can be ordered and plotted.

06 · RECOMMENDATIONS
What to do next
- 01Start proactive outreach for students who score high on several risk factors at once.
- 02Fund programmes that reduce financial stress.
- 03Add sleep screening and support to wellness services.
07 · TECHNICAL CHALLENGES
Problems solved along the way
- CHALLENGE 1Messy data typesKey columns mixed text and numbers and contained stray characters. Power Query cleaned and retyped them before any analysis.
- CHALLENGE 2Showing every studentPower BI aggregates by default. Using the Sleep Rank and the record ID on the scatter chart shows all 27,000+ students as separate points, so clusters are visible.
