- Study organism – Impatiens walleriana (Busy lizzy/ Patience Plant)
- I have chosen four different spots for Impatiens walleriana outside my work to observe. The environmental gradient I am going to observe for this plant is exposure to sunlight.
Spot no. 1 – sunlight all day
Spot no. 2 – sunlight after 9 am
Spot no. 3 – sunlight 11am to 5pm
Spot no. 4 – sunlight 2pm to 7pm
- Hypothesis – The number of flowers on Impatiens walleriana is affected by the amount of sunlight it receives.
Prediction – Impatiens walleriana plants that receive more sunlight will produce more flowers.
- Response variable – Number of Impatiens walleriana flowers
Explanatory variable – Amount of sunlight
thanks for the photos
Hi there,
For your explanatory variable, the amount of sunlight, how do plan to measure that variable? Since it is quite a subjective measurement, and less “exact”, how do you plan to counteract that for your stat analyses/results?
Also, it is a little unclear from this post if your study site it contained within that one garden or if it’s different areas. I mention this because the quality of soil (moisture, nutrients) may vary between gardens and may affect your results as confounding variables.
Great post!
