Interpretation and Drawing Conclusions
Observation and Analysis of Data
What is an example of Inference and Hypothesis?
Marsh grass grows better in some places.
Additional nitrogen was the reason it grew more in some areas than others.
Sampled plots, recorded data, and found experimental group is larger than the control group.
Marsh grass growth is limited by available nitrogen.
