# 3.7 Bivariate descriptive statistics: using spreadsheets to view  (Page 2/3)

 Page 2 / 3

Google Spreadsheet – You can create pivot tables in Google Spreadsheet as you did for univariate data however you have the same limitations, you cannot create row or column percentages unless you create them using formula (which you can do!) The only difference here is that you will again highlight two columns of data that you want to look at in the pivot table and select one for the rows and one for the columns. See the image below. Go back to Sampling and Data to get more details on how to find the Report Editor.

## Bar graphs (stacked and side by side):

In both Excel and Google Spreadsheet, it is very easy to create side by side or stacked bar graphs directly from your contingency tables. Highlight the fields on your contingency table (note do not highlight the totals column or any of the cell highlighted “blue”) and then go to your insert tab and insert a chart. See the fields highlighted (the area highlighted grey with a green border around it) in the figure below.

You have a choice of side by side or stacked. In Excel you can use your percentages. In Google Spreadsheet you will need to create your percentages if you want them in your bar graphs. Below is output from Excel and Google Spreadsheet. Both spreadsheet programs give you many options in the design and format modes. In Excel you can access the design you want from the Change Chart Type field on the Design Tab. In Google Spreadsheet you change chart types in the Chart editor under the start tab or the charts tab. Explore . . . it’s fun.

## Pie charts:

Pie charts are created the same way as bar graphs in Excel and in Google Spreadsheets using the pivot table . . . however you will need to change the order of the columns to create multiple pie charts. If you use the sort function in the PivotTable field (highlighted in green below) the field at the top of the PivotChart Fields, mouse over the down arrow, a popup menu will appear, pick a different sort option (a to z, z to a, or more sort options), and then the order of your columns will change. See Image of the popup menu below.

To make multiple pie charts you will need to copy the pie chart as a picture and paste it on your spreadsheet before you pick an alternative sort method. If you do not copy the pie chart as a picture, when you sort the data, you graph will change (it remains dynamic). Same is true when creating pie charts in Google Spreadsheet.

## Optional classroom exercise for categorical –categorical data:

At your computer, try this exercise: (1) Open the file, Statistics First Day of Class Survey that you worked on previously (2) open the file in Google Spreadsheet or Excel; (3) create a new worksheet tab and label it Bivariate Graphs for Categorical Data; (4) pick two column of data that are categorical and has been “cleaned” and create a contingency table, side by side bar graphs and side by side pie graphs with all the appropriate labels; And (5) save the file again and post in the appropriate Moodle assignment.

## Categorical - numerical

When working with categorical and numerical data and Excel or Google Spreadsheet, one of the best first steps is again, to copy the columns of data from your working data sheet to a new spreadsheet, and label the spreadsheet. The next step will be to sort the data. You must be sure to sort both columns of data together. The data from the categorical column and the numerical column are related. They are a pair of data from the same source. In examining categorical – numerical data we want to know what is the relationship between the two responses, so we must keep the two columns together.

can someone help me with some logarithmic and exponential equations.
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

what is a good calculator for all algebra; would a Casio fx 260 work with all algebra equations? please name the cheapest, thanks.

kkk nice
algebra 2 Inequalities:If equation 2 = 0 it is an open set?
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
what is system testing
what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
how did you get the value of 2000N.What calculations are needed to arrive at it
