Calc frequency density: freq 18, width 5
Calc frequency density: freq 18, width 5
Frequency density = 18 ÷ 5 = 3.6
Calc frequency density: freq 14, width 10
Calc frequency density: freq 14, width 10
Frequency density = 14 ÷ 10 = 1.4
Label the vertical axis for unequal widths
Label the vertical axis for unequal widths
Label the vertical axis as 'Frequency density'
