It displays the frequencies (or counts) of observations falling into different intervals, or “bins,” along the horizontal axis, with the vertical axis representing the frequency or density of observations within each bin. Histograms are commonly used for exploring the underlying distribution of continuous numerical data.

II. Strengths of Histograms:

1. Visualization of Distribution:

• Histograms provide an immediate visual sense of the shape, central tendency, and spread of the data distribution. Patterns such as skewness, modality, and outliers can be easily identified.

2. Ease of Interpretation:

• Histograms are easy to understand and interpret, making them accessible to a wide audience, including those with limited statistical background.

3. Bin Flexibility:

• The choice of bin width allows for flexibility in emphasizing different aspects of the data distribution. Adjusting bin width can reveal fine details or provide a more general…
