Descriptive Statistics Lab

Name:

## A. student learning objectives

• The student will construct a histogram and a box plot.

• The student will calculate univariate statistics.

• The student will examine the graphs to interpret what the data implies.

## B. collect the data

Record the number of pairs of shoes you own:

1. Randomly survey 20 people. Record their values. Survey Results

_____ _____ _____ _____ _____ _____ _____ _____ _____ _____

_____ _____ _____ _____ _____ _____ _____ _____ _____ _____

2. Construct a histogram using Minitab. Choose an appropriate scale and use boundary values (cut points).

3. Calculate the following: Be sure to include the formulas and the appropriate values. Show your work

$\overline{x}$ =

• s =

4. Are the data discrete or continuous? How do you know? Use complete sentences.

5. Describe the shape of the histogram. Use 2 – 3 complete sentences.

## C. analyze the data

1. Determine the following and show your work where appropriate:

• Minimum value =

• Median =

• Maximum value =

• First quartile =

• Third quartile =

• IQR =

2. Using Minitab, construct a box plot of data.

3. What does the shape of the box plot imply about the concentration of data? Use 2 – 3 complete sentences.

4. What does the IQR represent in this problem ? (reference your values)

5. Are there any potential outliers? Which value(s) is (are) it (they)?

Use the formula to calculate the two end values used to determine if a data value is an outlier.

upper =

lower =

6. Show your work to find the value that is 1.5 standard deviations:

a. Above the mean:

b. Below the mean:

c. What percent of the data does Chebyshev’s theorem state lies within 1.5 standard deviations of the mean? (show your work.)

d. What percentage of your data actually falls within 1.5 standard deviations of the mean? How does this compare to the value you calculated in part c above?

7. How does the standard deviation help you to determine concentration of the data and whether or not there are potential outliers?

are nano particles real
yeah
Joseph
Hello, if I study Physics teacher in bachelor, can I study Nanotechnology in master?
no can't
Lohitha
where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts
Bhagvanji
hey
Giriraj
Preparation and Applications of Nanomaterial for Drug Delivery
revolt
da
Application of nanotechnology in medicine
has a lot of application modern world
Kamaluddeen
yes
narayan
what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
