Essay / Research Paper Abstract
This page paper is an example of how to use scientific method to prove or disprove a theory or hypothesis. The paper uses the example of proving that grass which is watered will grow more rapidly that grass which is not watered. The paper demonstrated the use of an hypothesis test using a Chi Squared test. The calculation is also shown. The bibliography cites 2 sources.

Unformatted sample text from the term paper:
to an external appearance, but grass in a garden may be seen as having a major visual impact. The student has noticed that the grass in their own garden is
short and brown, not looking healthy, what the grass in the garden next door is green, lush and grows at a healthy rate. The problem in this case is to
discover what it is that makes the grass grow in the neighbours garden and not in the students own garden. To use scientific method we need to develop an
hypothesis. To develop the hypothesis we need to consider the factors that could account for this difference. Looking at issues of grass growth and lawn care there are several
factors that could account for the difference. It is established that different types of grass need different levels of water and also require different soil types to thrive (Abraham, et
al, 2004). However, in this case the grass types are the same, this has been confirmed by a botanist. Other factors may include differences such as a change in
soil type between the two gardens, different levels of sun and shade, different treatment with chemicals such as weed killers or fertilisers. In this case we will assume the student
has followed all of these through with the neighbour and there were no differences the soil was tested and there were no chemical differences in the treatment, neither neighbour is
using any treatment. This leaves the student with only one variable; the level of watering. Through basic observation the only notable difference was the watering pattern, the student does
not water the grass whereas the neighbour does water the grass. This is leads us to the hypothesis (H1) that the grass in the neighbours garden is growing
