Understanding Histograms and Bar Charts

Both histograms and bar charts help us see data, but they are a bit different from each other.

1. Data Type:

   • Histograms show continuous data. This means they represent things that can change smoothly, like heights or weights. The bars in a histogram touch each other because this data is divided into groups or "bins."
   • Bar Charts display categorical data, which is information that can be divided into different categories. This could be people's favorite colors or types of pets. In a bar chart, each bar is separate and doesn’t touch.

2. Bar Width:

   • In a histogram, the width of each bar shows a range of data.
   • In a bar chart, all the bars have the same width.

3. Examples:

   • A histogram could show how students scored on a test.
   • A bar chart could show how many students like different sports.

So, remember: Use a histogram for continuous data and a bar chart for categorical data! It's that simple!
