Qualitative data is derived from broad question and is expressed in the form of word responses from study participants. Include any statistical tests and their results in this section. Make sure data is both graphed or diagrammed as well as described. All graphs and diagrams should have a number and title. For example, if if you are testing the effect of fertilizer on plant growth you would want a graph showing the average growth of plants given fertilizer.

For example, if you were testing how fertilizer affected plant growth, you would want to state what brand of fertilizer you used, what species of plant you used and brand of seed. If is often helpful to include a diagram of how these materials were set. Make sure you include the quantity of all objects used in the experiment. 3 Describe the exact procedure you used. Write this in terms of detailed steps.


8 Remember all experiments involve controls and variables. Write down, step by step, a set of detailed instructions on how you did the experiment. Include descriptions of all measurements made and how/when they were recorded. Describe any steps you took to reduce experimental uncertainty.
