Identify the x-axis, which shows the variable or value ranges
Identify the y-axis, which shows frequency, count, or percentage
Look at the bars to see how often values fall within each range
Compare bar heights to find the most common range
Check the spread to see how widely the data is distributed
Look for gaps where no data appears
Look for peaks where data clusters
Look for skewness by seeing whether one side has a longer tail
Compare multiple histograms by matching their shapes, centers, and spreads
Read the bin width to understand how data is grouped
Use the histogram to estimate the center of the data
Use the histogram to estimate variability in the data
