Histograms (Leaving Cert Mathematics): Flashcards

Continuous data

Distribution of data across intervals

Frequency density

$\frac{\text{Frequency}}{\text{Group Width}}$

Difference between upper and lower limits of interval

Frequency density

To show the data is continuous

Shape and distribution

$\text{Frequency} = \text{Frequency Density} \times \text{Group Width}$

Continuous data intervals
