Explanation:
di po ako sure Kung Tama pero feel free to copy my answer. I hope it helps.
Plantation of the 30 pechay seeds is an independent variable, growth is a dependent variable, and type of soil is an extraneous variable:
- Independent variable: This variable doesn't depend on any circumstance or other variable.
- In the given case, the plantation of the seeds is an independent action and not dependent on any other variable.
Thus, the independent variable, in this case, is the plantation of the 30 pechay seeds into variable soil samples.
- Dependent variable: It is a type of variable that depends on a given factor/ circumstance/ other variables.
- In the given case the growth of the plant is a type of action dependent on various factors.
Thus, the dependent variable, in this case, is the growth of the pechay plants in different soil samples.
- Extraneous variable: It is a type of variable that is not being considered as a part of the study but can cause changes/ affect the results.
- In this case, choosing the type of soil is not used in the investigation.
Thus the extraneous variable is the type of soil chosen, that is soil purchased from an online seller, soil from backyard compost, and the soil underneath the nearby bamboo tree.
