### Week 2 Problem Set 2: Bar Charts and Histograms

**Due Date: Sunday, June 28**

---

**Instructions:**

Your submission to Canvas will include two bar charts, a grouped frequency table, and a grouped frequency histogram.

1. **Major Distribution Table:**
   - Below is a table listing the majors of 18 Chabot College students:
   
     | Major                       | Number of Students |
     |-----------------------------|--------------------|
     | Administration of Justice   | 2                  |
     | Business                    | 4                  |
     | Kinesiology                 | 3                  |
     | Psychology                  | 6                  |
     | Sociology                   | 3                  |
     | **TOTAL**                   | **18**             |
   
   a. **Bar Chart 1:** Create a bar chart that shows this information with the y-axis representing frequency. 

   b. **Bar Chart 2:** Create a second bar chart with the y-axis representing percentages instead of counts.

   c. **Data Analysis:** Although you do not need to write this down, be prepared to describe the patterns you observe in the data. This will be part of the exam.

2. **Child Weight Distribution:**
   - This problem involves creating groups for 50 scores of child weights, then creating a grouped frequency table. Finally, you will create a histogram that shows the same information as the grouped frequency table.

**Explanation of Histogram:**

A histogram is used because the variable (children's weight) is measured at the interval level. The bars in a histogram touch each other, representing continuous data divided into intervals.

**End of Instructions**

Ensure your submission meets all requirements and reflects your understanding of how to represent data visually using bar charts and histograms. Good luck!
