    Frequency. Frequency is the vegetation attribute that describes the probability of finding a species within a particular area. The probability is based on the occurrence of that species in a series of sample units.For example, if a species has a frequency of 75%, we expect it to occur in three out of every four quadrats examined Frequency is expressed as a value between 0% and 100%

  • How to Determine the Right Oil Sampling Frequency

    Unless you are lucky, you can only expect to accomplish this by sampling at a frequency higher than the FDP. The FDP can be anywhere from a few months to a few hours. Considering that it would be too costly to sample every hour and of little use to sample outside of a few months, the ideal frequency can be cost justified somewhere in between
