Lesson

Steps for creating a histogram

1. Determine the Range: \(~~~Range = Maximum - Minimum\)
2. Determine the number of bins
   • Sample Size = n
   • How many times do you need to double to reach n?
3. Create the bins
   • Bin Size: \(~~~Bin~Size = \frac{Range}{n}\)
   • Starting point
     • First bin starts at minimum
     • Add the bin size to the minimum to get the start of the second bin
     • Add the bin size to that to get the start of the third bin
     • …
4. Count your data
   • Count how many datapoints in your dataset fit in each bin
