the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.

Climate change cannot be
measured with a single instruments but require thousands of measuring devices
that spread across the globe, land and under the sea. Thus,parameters
measured in climate change includes: Rainfall, Sunshine hours, Temperature, Relative
humidity, Atmospheric pressure, Wind speed .
However, there are various instruments used for the measuring of climate
change and they can be classified as follows: weather balloons and buoys, thermometers, wind anemometers,
Manual rain gauges, transmitting rainfall gauges and Automatic Weather
Stations
