Frequency The frequency is the number of times an event occurs during the course of your experiment and is often presented in a table or a graph.  For example, you could be conducting an experiment looking at the rate of flower development of Arabidopsis thaliani.  For each particular dissection date, you want to  produce a frequency table to represent the number of flowers at each stage of development: Flower Stage Frequency 0 2 1 9 2 26 3 25 4 10 5 3 It's not uncommon to look at the percentage frequency as well, which is calculated by dividing each entry by the total number of entries, so for flower stage 0, the percentage frequency is calculated using the equation: 2/(2+9+26+25+10+3) * 100 = 2.67%. The frequency can then be used to create a distribution graph.
