Answer

Select the Survey Area: The student would first choose a specific habitat close to her home.
Divide the Area: She should divide the area into quadrants to ensure systematic sampling.
Random Sampling: Use a random or unbiased method to select specific quadrants for observation.
Count and Record: In each selected quadrant, the student would count the frequency of each plant type and record the observations carefully.
Repeat Measurements: This process should be repeated across different stations to ensure accuracy.
Calculate Percentage: Finally, she would calculate the percentage frequency of each plant type by dividing the count by the total number of samples.
