No gaps between bars (they touch)
Frequency - how often values occur in that class
Equal class intervals (same range of values)
Label both axes clearly
Class interval with the highest frequency
Identify which class has the highest frequency
(n+1)÷2(n + 1) \div 2(n+1)÷2
Add frequencies from lowest until reaching median position
As an interval/range (e.g., 30-40), not single number
Histogram: continuous; Bar chart: discrete
Confusing mode (exact value) with modal class (interval)
