Quadrat Method vs. Transect Method Question: What is the population density of weeds in Newtonbrook’s football field? Hypothesis: Considering the experimental data was taken very early in the spring, the quadrats will each have 40 plants, and the transect will have 160 plants. The quadrat method will yield the most accurate results, and the field would need pesticides. Observations: Group: Quadrat 1 Quadrat 2 Quadrat 3 Quadrat 4 Transect Kia 29 20 17 19 91 Sahar 32 44 5 25 52 Sam 5 8 6 12 27 Yelena 43 30 148 ------- 132 Rachel 149 89 235 223 976 Min 6 13 17 45 97 Calculations: 1. Quadrat average density: D= (29+20+17+19)/4/1 Transect Average Density: D= 91/(4x1) D= 21.25 weeds/m 2 D= 22.75 weeds/m 2 2. Quadrat Average Density: D=(29+20+17+19+32+44+5+25+5+8+6+12+43+30+148+149+89+235+223+45+17+13+6)/23/1 D= 53 weeds/m 2 Transect Average Density: D= (91+52+27+132+976+97)/6/(4x1) D= 57.3 weeds/m 2 Analysis: 1. Our group’s results yielded almost half of the class’s average densities for both the transect and quadrats. Even though our group’s results suggested a lower population

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
