Project 1: Chapters 1-3

For this project, we will investigate the structure of one of the best known

databases found in pattern recognition literature. We will use techniques from the first

three Chapters of our zyBooks text. Be sure you have completed both the reading

assignments and homework before working this project. You are not required to have

any prior knowledge of software such as Google Sheets and may ask me any questions

about software and technology. Please feel free to email me, contact me via campus, or

set up an appointment to discuss your work

Background:

R. A. Fischer was an active as a mathematician, statistician, biologist, geneticist,

and academic. We will investigate the structure of a data set examined by Fischer.The

original data set contains 3 classes where each class refers to a type of iris plant. We

will restrict our scope to one type of iris, Iris Setosa. For a class of iris, measurements of

the length and width of two specific structures were made. The length and width of the

petals as well as the length and width of the sepals were recorded. Please see Figure 1

to see the various locations and click on the link in the caption of Figure 1 if you want

more information. You need not be a plant biologist to complete this project.

Befacts./n8. Find the median of your sample.To do so, go to an empty cell in your Work

Sheet. Type "=MEDIAN (cell beginning : cell end)" without the quotation marks

and where cell beginning and cell end refer to where you pasted your data. Note

that the median is found by first putting the data in increasing order and then

finding the value that divides the data in half with half below and half above.
