A bar chart is a type of graph that uses rectangular bars (vertical or horizontal) to represent data. The length or height of each bar corresponds to the value it represents.
Key Features:
Bars can be vertical (column chart) or horizontal.
Each bar represents a category.
The size of the bar shows the quantity, frequency, or percentage.
Bars are usually separated by some space (unlike histograms).
Best Fit Data for Bar Charts:
Bar charts are best for categorical data (data divided into groups). Some examples:
Comparing categories
Sales by product type
Population by country
Number of students in each grade
Frequency distributions (counts of categories)
Favorite colors chosen in a survey
Types of transport used by employees
Discrete data (not continuous)
Number of cars sold in different months
