Frequency Learning Objectives

After completing this module, students will be able to:

  1. Define frequency and describe situations or applications in which measuring frequency is appropriate.
  2. Differentiate between advantages and disadvantages of frequency data.
  3. Describe the kinds of decisions about ground rules (such as selecting frequency frame size, sample size) that must be determined to measure frequency.
  4. Be able to determine the appropriate quadrat size to estimate frequency of individual plant species, and be able to select the appropriate quadrat size using nested quadrats .
  5. Use Chi Square Analysis to determine whether frequency measurements are significantly different.
  6. Given a small data set, be able to calculate frequency, determine the appropriate quadrat size, and analysis frequency data using Chi Square Analysis.
