• ${Y}_{\mathrm{scl}}=1$ (spacing of tick marks on y-axis)
• ${X}_{\mathrm{res}}=1$

To draw box plots:

1. Access graphing mode.

, [STAT PLOT]

2. Select <1:Plot 1> to access the first graph.

3. Use the arrows to select <ON> and turn on Plot 1.

4. Use the arrows to select the box plot picture and enable it.

5. Use the arrows to navigate to <Xlist>
6. If "L1" is not selected, select it.

7. Use the arrows to navigate to <Freq> .
8. Indicate that the frequencies are in [L2] .

, [L2] ,

9. Go back to access other graphs.

Sample data

The following data is real. The percent of declared ethnic minority students at De Anza College for selected years from 1970 - 1995 was:

Year Student Ethnic Minority Percentage
1970 14.13
1973 12.27
1976 14.08
1979 18.16
1982 27.64
1983 28.72
1986 31.86
1989 33.14
1992 45.37
1995 53.1
The TI-83 has a built-in linear regression feature, which allows the data to be edited.The x-values will be in [L1] ; the y-values in [L2] .

To enter data and do linear regression:

1. ON Turns calculator on

2. Before accessing this program, be sure to turn off all plots.
• Access graphing mode.

, [STAT PLOT]

• Turn off all plots.

,

3. Round to 3 decimal places. To do so:

, [STAT PLOT]

• Navigate to <Float> and then to the right to <3> .

• All numbers will be rounded to 3 decimal places until changed.

4. Enter statistics mode and clear lists [L1] and [L2] , as describe above.

,

5. Enter editing mode to insert values for x and y.

,

6. Enter each value. Press to continue.

To display the correlation coefficient:

1. Access the catalog.

, [CATALOG]

2. Arrow down and select <DiagnosticOn>

... , ,

3. $r$ and $r^{2}$ will be displayed during regression calculations.
4. Access linear regression.

5. Select the form of $y=a+bx$

,

The display will show:

Linreg

• $y=a+bx$
• $a=-3176.909$
• $b=1.617$
• $r^{2}=0.924$
• $r=0.961$

This means the Line of Best Fit (Least Squares Line) is:

• $y=-3176.909+1.617x$
• $\mathrm{Percent}=-3176.909+1.617\mathrm{\left(year #\right)}$
The correlation coefficient $r=0.961$

To see the scatter plot:

1. Access graphing mode.

, [STAT PLOT]

2. Select <1:plot 1> To access plotting - first graph.

3. Navigate and select <ON> to turn on Plot 1.

<ON>

4. Navigate to the first picture.
5. Select the scatter plot.

6. Navigate to <Xlist>
7. If [L1] is not selected, press , [L1] to select it.
8. Confirm that the data values are in [L1] .

<ON>

9. Navigate to <Ylist>
10. Select that the frequencies are in [L2] .

, [L2] ,

11. Go back to access other graphs.

, [STAT PLOT]

12. Use the arrows to turn off the remaining plots.
• ${X}_{\mathrm{min}}=1970$
• ${X}_{\mathrm{max}}=2000$
• ${X}_{\mathrm{scl}}=10$ (spacing of tick marks on x-axis)
• ${Y}_{\mathrm{min}}=-0.05$
• ${Y}_{\mathrm{max}}=60$
• ${Y}_{\mathrm{scl}}=10$ (spacing of tick marks on y-axis)
• ${X}_{\mathrm{res}}=1$
14. Be sure to deselect or clear all equations before graphing, using the instructions above.
15. Press to see the scatter plot.

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

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
Alexandre
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 .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
how did you get the value of 2000N.What calculations are needed to arrive at it
