Lesson 2 Quiz:
Introduction to Plot Sampling

Check your knowledge by answering the following multiple-choice questions:

1. Suppose you want to do an inventory in a 70-acre stand. What is the recommended minimum number of plots for this stand?

a. 3

b. 4

c. 5

d. 7

2. Suppose you want to do an inventory in a 4-acre stand. What is the recommended minimum number of plots for this stand?

a. 1

b. 2

c. 3

d. 5

3. Suppose you want to do an inventory in a 70-acre stand. The stand is very uniform young timber. What does this mean in terms of how many plots you may want to put in?

a. Consider putting in a minimum of plots because of the uniformity.

b. Consider putting in more than the minimum of plots because of the uniformity.

c. Uniformity has no bearing on how many plots you should put in.

4. Suppose you want to do an inventory of a stand that has a road running through the center of it. Would it be ok to locate your plots along this road?

a. No, because locating plots along a road is not systematic and could introduce bias.

b. No, because it is better to sample the outer edges of the stand rather than the middle.

c. Yes, because the road runs through the middle of the stand.

d. Yes, because it is better to put plots near an easily identifiable feature on the ground.

5. Suppose you want to inventory a 70-acre stand. You establish a 5 chain grid, which results in 25 plot locations. You do not wish to do more than 10 plots. What should you do?

a. Do the first 10 plots, then stop.

b. Pick which 10 plots you want to do in advance, based on locations that are easy to get to.

c. Widen your grid to get fewer plots.

d. You must do all 25 plots.
