How does a histogram differ from a bar graph in terms of data representation?

• Histograms and bar graphs are essentially the same

• Histograms show continuous data ranges, while bar graphs show discrete categories

• Histograms show individual data points, while bar graphs show data ranges

• Histograms show qualitative data, while bar graphs show quantitative data

Why do histograms not have spaces between the bars?

• Because it is a stylistic choice

• To indicate that the data is continuous

• To save space on the graph

• To make the graph easier to read
