How are histograms different from bar graphs?

• Histograms have no gap between the bars, while bar graphs do.

• Bar graphs use adjacent bars, while histograms do not.

• Histograms compare categories, while bar graphs compare distributions.

• Bar graphs show continuous data, while histograms show discrete data.

What do bar graphs compare?

• Categories

• Distribution of data

• Continuous data

• Frequencies only

What does the histogram in the image represent?

• The heights of Black Cherry Trees

• The weights of apples

• The ages of students

• The number of books read

In a histogram, what does the height of each bar represent?

• The frequency of data points in each bin.

• The average value of the data.

• The total number of bins.

• The range of the data.
