Estimating Daisy Plant Population

The video tutorial explains how to estimate the population of daisy plants on a lawn using a sampling method with quadrats. It covers identifying daisy plants, setting up a sampling area, using a random number table to avoid bias, and counting daisies within quadrats. The tutorial also discusses how to handle edge cases and calculate the total population estimate by sampling 10% of the area and multiplying the count by 10.

What is the size of the area used for estimating the Daisy plant population?

• 10 meters by 10 meters

• 5 meters by 5 meters

• 5 meters by 10 meters

• 10 meters by 5 meters

When identifying Daisy plants, what should be ignored?

• The roots

• The stems

• The flowers

• The leaves

What tool is used to sample the Daisy plants on the lawn?

• A ruler

• A quadrat

• A compass

• A protractor

How much of the lawn area should be covered by quadrats for sampling?

• 10%

• 5%

• 15%

• 20%

What method is used to avoid bias when placing quadrats?

• Using a GPS

• Using a compass

• Using a random number table

• Using a map

Why is it important to avoid bias in sampling?

• To save time

• To ensure accurate results

• To use fewer quadrats

• To make the process easier

How should Daisy plants on the edges of a quadrat be counted?

• Count only those on the left and bottom edges

• Count all edge plants

• Ignore all edge plants

• Count only those on the top and right edges

What is the purpose of multiplying the counted Daisies by 10?

• To account for errors

• To adjust for weather conditions

• To simplify calculations

• To estimate the total population

What is the main goal of this practical task?

• To measure the lawn area

• To remove unwanted plants

• To estimate the population of Daisy plants

• To plant more daisies

What is the significance of using a random number table?

• To ensure even distribution

• To avoid bias in quadrat placement

• To reduce the number of quadrats needed

• To increase the number of samples
