Describe your field data collection activities.
- Sampling strategy:
- Area sampling method using a 1m2 quadrat.
- Simple random sample placement
- My hypothesis: changes in weather reduces the abundance of Birdsfoot Trefoil plants in grasslands.
- Sample unit: lawn (grassland area infront on my apartment)
- I carried out the experiment on 5 days over the space of 8 weeks as the weather/season changes from summer (sunny and warm) to fall (chilly, cool, windy).
- I took my quadrat and randomly dropped it 15 times and counted the number of birdsfoot trefoil plants that fell inside the quadrat.
- My 5 replicates were taken on 5 different days
- August 1st: 27℃ sunny, warm
- August 15th: 27℃ sunny, warm
- August 30th: 25℃ sunny, warm
- September 10th: 20℃ chilly, cool
- September 20th: 16℃ chilly, cool
How many replicates did you sample?
- 5 replicates on 5 different dates
- August 1st
- August 15th
- August 30th
- September 10th
- September 20th
Have you had any problems implementing your sampling design?
- I had no problems as I went out to carry out my experiments when it was not windy so the wind doesnt move my quadrat and affect my data.
- This was my way of avoiding any statistical bias
Have you noticed any ancillary patterns that make you reflect on your hypothesis?
- My hypothesis: changes in weather reduces the abundance of Birdsfoot Trefoil plants in grasslands.
- I am more confident in my hypothesis now because I can see that there is a reason why Birdsfoot trefoil plants die off before winter approaches while other plants have a slower reaction to the change in weather
