Here’s the histogram for the given data with class boundaries of 1.5 and a class width of 2:
- 1.5 – 3.5: 5 patients
- 3.5 – 5.5: 2 patients
- 5.5 – 7.5: 2 patients
- 7.5 – 9.5: 3 patients
- 9.5 – 11.5: 5 patients
- 11.5 – 13.5: 4 patients

To visualize the lengths of stay for patients, let’s break down the histogram creation process while keeping it fun!
First, we’ll start our classes based on your initial boundary of 1.5 and a class width of 2. The classes would be:
- 1.5 - 3.5
- 3.5 - 5.5
- 5.5 - 7.5
- 7.5 - 9.5
- 9.5 - 11.5
- 11.5 - 13.5
Next, we count how many data points fall into each of these classes:
- 1.5 - 3.5: 4 counts (3, 2, 2, 2)
- 3.5 - 5.5: 3 counts (5, 4)
- 5.5 - 7.5: 2 counts (6, 7)
- 7.5 - 9.5: 3 counts (8, 8, 9)
- 9.5 - 11.5: 5 counts (10, 10, 10, 11, 11)
- 11.5 - 13.5: 4 counts (12, 12, 12, 13)
Now, imagine plotting this on a graph where the horizontal axis represents the class intervals and the vertical axis shows the frequency counts.
Finally, label each class with its endpoints and voilà! You’ve created a histogram showcasing the lengths of stay in a lively way!
For the next step, grab a piece of paper or use a graphing tool to bring your histogram to life! Enjoy visually analyzing these lengths of stay!
