**Analyzing Singer Heights through One-Way ANOVA**

This educational activity explores the relationship between the type of singer and their height using a statistical method called One-Way ANOVA. The data presented originate from the DASL (The Data and Story Library) database, specifically focusing on the heights (in inches) of different types of singers.

**Graph Explanation:**

The scatter plot visually presents the height distributions across four categories of singers: Soprano, Alto, Tenor, and Bass. Each category is represented by differently colored dots:
- **Soprano**: Blue
- **Alto**: Orange
- **Tenor**: Gray
- **Bass**: Yellow

The y-axis denotes height in inches, ranging from 55 to 80 inches. The plot shows variability in height within each singing category, helping assess whether these differences are statistically significant.

**ANOVA Summary Table:**

The summary table lists statistical details for each singer group:

- **Soprano**: 
  - Count: 36
  - Sum of Heights: 2313 
  - Average Height: 64.25 inches
  - Variance: 3.5071

- **Alto**: 
  - Count: 35
  - Sum of Heights: 2271 
  - Average Height: 64.885714 inches
  - Variance: 7.8101

- **Tenor**: 
  - Count: 20
  - Sum of Heights: 1383 
  - Average Height: 69.15 inches
  - Variance: 10.3447

- **Bass**: 
  - Count: 39
  - Sum of Heights: 2758 
  - Average Height: 70.717949 inches
  - Variance: 5.5762

**ANOVA Statistical Output:**

- **Source of Variation**: 
  - **Between Groups**: 
    - Sum of Squares (SS): 1058.5289
    - Degrees of Freedom (df): 3
    - Mean Square (MS): 352.84298
    - F-value: 55.800134
    - P-value: 5.1E-23 (significant at conventional levels)
    - F critical (F crit): 2.67652

  - **Within Groups**:
    - Sum of Squares
