Frequency density of a class is computed by the ratio
Elementary MathematicsStatistics
- AClass frequency to the class width
- BClass frequency to total frequency
- CClass frequency to total number of classes
- DCumulative frequency up to that class to total frequency
Explanation
Frequency density normalizes frequency by class width: class frequency ÷ class width (the quantity plotted in histograms with unequal class widths). Hence option (A).
