DESCRIPTION
Relative Frequency. How to calculate relative frequency. Noemi Navas Arranz. 1. First of all, count the number of times that each piece of data is repeated. IIII. IIII. IIII. IIII. This is the absolute frequency. IIII. IIII. IIII. IIII. 2. Next, count the total number of events. - PowerPoint PPT PresentationTRANSCRIPT
