Question: Percantagewise who participated in the survey?
SQL:
SELECT ResponderDescription, COUNT(ResponderDescription) * 100.0 / SUM(COUNT(ResponderDescription)) OVER () AS percentage FROM Responses WHERE NOT ResponderDescription IS NULL GROUP BY ResponderDescription
SELECT COUNT(*) * 100.0 / (SELECT COUNT(*) FROM Responses) AS ParticipationPercentage FROM Responses WHERE NOT SurveyAgreement IS NULL
