1. Histograms vs. Bar Charts
Histogram:
Use when: You want to show the distribution of continuous data (e.g., ages, heights, test scores).
Key feature: Bars touch each other because the data is continuous.
Example: Number of students in different age ranges (10–12, 13–15, etc.).
Bar Chart:
Use when: You want to compare categories of discrete data.
Key feature: Bars are separated because the categories are distinct.
Example: Number of students in each grade (Grade 6, Grade 7, Grade 8).
