47 Survey Responses by Age Range and Interest Level
What This Shows
The 9-11 bar is the clearest concentration of definite interest: 14 of that group's 23 responses say they would definitely attend.
A club needs concentrated interest in one age range, not scattered interest across four. Totalling all 47 responses hides that; grouping them reveals it. Toggle 'Not interested' off with the legend and the 9-11 concentration becomes even starker.
