1. The problem asks: Who had less variation in her daily step count, Janet or Brenda? 2. Variation in data is often measured by the interquartile range (IQR), which is the length of the box in a box plot. The IQR is calculated as $$\text{IQR} = Q_3 - Q_1$$ where $Q_1$ is the first quartile and $Q_3$ is the third quartile. 3. From the box plots, estimate the quartiles for Janet and Brenda: - Janet's box (green) spans approximately from 6,000 to 9,000 steps. - Brenda's box (pink) spans approximately from 5,500 to 8,000 steps. 4. Calculate the IQR for each: - Janet: $$\text{IQR}_J = 9000 - 6000 = 3000$$ - Brenda: $$\text{IQR}_B = 8000 - 5500 = 2500$$ 5. Since Brenda's IQR (2500) is less than Janet's IQR (3000), Brenda had less variation in her daily step count. **Final answer:** Brenda had less variation in her daily step count.
