Work backwards from your idea! 1. What statements do you want to make? 2. What variables are needed to make those statements? 3. Who would collect data with those variables? 4. How will you get the data from the collector?
1. Statements? Lede = hypothesis Bullet points = statements Examples for a crime and courts data story: “Crime has increased/decreased X % since...” “The X per violent crime rate of Y City is the worst...” “Only X % of reported crimes result in arrests...”
2. Variables needed? Columns = variables Rows = records Two main kinds of variables Categorical: Sex, city, postal code, type of crime, etc... Numeric: Age, cost, population, weight, arrests, accident, etc...
3. Who collects those variables?
4. Get the data!
