# Comparative Analysis

Introduction

Planning Objective: We aimed in examining the appearance or distribution of 3 plant species in a field. We went to a field, there, each group was given a quadrant and a set of 15 different instructions. We had to follow those instructions one by one (i.e. 1. go 15 steps north, 2. 7 steps east etc.), after each instruction we had to put our quadrant down and count the number of plants of each species. In order to make the experiment fair, each group went to 15 different parts of the field. This way we covered a significant area of the field. When we went back to class we got the results from all the groups. We had to find the average number of plants per square meter. Some numbers were considered as extreme data and were not included into any calculations. Numbers considered as extreme data were numbers which were too high and did not follow the pattern of the rest of the data. ...read more.

Species B is somewhere in between with 22,09%. In the future, we can do this experiment in a few nearby fields. We can collect more values, to make the experiment fairer. The experiment could have been done in a more correct way if we used a long measuring tape or if the groups were more. ?? ?? ?? ?? Comparative Analysis Page 1 of 5 Rafaela Fylactou ...read more.
