'''Title Slide'''<br />
| | Welcome to this '''tutorial''' on '''Statistics using GeoGebra'''<br />
|-<br />
| | '''Slide Number 2'''<br />
<br />
'''Learning Objectives'''<br />
| | In this '''tutorial''', we will learn how to use '''GeoGebra''' to perform:<br />
<br />
'''One Variable Analysis''' to calculate different statistical parameters<br />
<br />
'''Two Variable Regression Analysis''' to estimate best fit line<br />
<br />
'''Multiple Variable Analysis''' to calculate different statistical parameters<br />
|-<br />
| | '''Slide Number 3'''<br />
<br />
'''System Requirement'''<br />
| | Here I am using:<br />
<br />
'''Ubuntu Linux '''OS version 16.04<br />
<br />
'''GeoGebra''' 5.0.481.0-d<br />
|-<br />
| | '''Slide Number 4'''<br />
<br />
'''Pre-requisites'''<br />
| | To follow this '''tutorial''', you should be familiar with:<br />
<br />
'''GeoGebra''' interface<br />
<br />
Statistics<br />

<br />
'''Statistics'''<br />
<br />
Data analysis and interpretation<br />
<br />
'''Measures of central tendency'''<br />
<br />
'''Measures of Dispersion'''<br />
<br />

<br />
'''Statistics'''<br />
<br />
Statistics deals with<br />
<br />
Data analysis and interpretation<br />
<br />
Measures of '''central tendency'''<br />
<br />
Measures of '''Dispersion'''<br />
<br />
Comparing '''variability''' of data series<br />
<br />
Please refer to '''additional material''' provided along with this '''tutorial'''.<br />
|-<br />
| | '''Slide Number 6'''<br />
<br />
'''Measures of central tendency'''<br />
<br />
'''Arithmetic mean '''<br />
<br />
'''Median'''<br />
<br />
'''Mode'''<br />
| |<br />
<br />
'''Measures of central tendency'''<br />
<br />
Measures of '''central tendency''' include '''arithmetic mean, median''' and '''mode'''.<br />
<br />
They give an idea about centering of data points.<br />
|-<br />
| | '''Slide Number 7'''<br />
<br />
'''Measures of Dispersion'''<br />
<br />
'''Range'''<br />
<br />
'''Quartiles'''<br />
<br />
'''Mean'''<br />
<br />
'''Standard Deviation (σ) = sqrt (variance)'''<br />
| |<br />
<br />
'''Measures of Dispersion''' include '''Range, Quartiles, Mean''' and '''Standard Deviation'''.<br />
<br />
'''Range''' is the difference between the highest and lowest data points.<br />
<br />
'''Quartiles''' are the data points that divide the list into quarters<br />
<br />
'''Mean''' is the sum of all data points divided by the number of points.<br />
<br />
'''Standard deviation, sigma''', is the '''squareroot''' of '''variance'''. <br />
It describes how spread out the data are.<br />
|-<br />

<br />
'''Fish Feed '''<br />
<br />
A fishery is testing four feed formulations on its fish: '''A, B, C''' and '''D'''<br />
<br />
Length (mm)<br />
<br />
Weight (lbs)<br />
<br />
Girth (mm)<br />
<br />
| | '''Fish Feed '''<br />
<br />
Let us look at an example.<br />
<br />
A fishery is testing four types of feed formulations on its fish: '''A, B, C''' and '''D'''.<br />
<br />
Data to be collected after feeding the fish for 6 months are:<br />
<br />
Length in millimeters<br />
<br />
Weight in pounds<br />
<br />
Girth in millimeters<br />
<br />
Let us look at some of these data.<br />
|-<br />
| | '''Slide Number 9'''<br />
<br />
'''Fish Feed Data'''<br />
<br />
<br />
[[Image:]]<br />
| | We will use these data for our '''analyses'''.<br />
<br />
Please download the '''code file''', '''Fishery-data''', provided along with this '''tutorial'''.<br />
|-<br />
| | '''Slide Number 10'''<br />
<br />
'''Box Plot'''<br />
<br />
[[Image:]]<br />
| | '''Box Plot'''<br />
<br />
'''Box plot''' is a standardized way of showing data, based on the '''five number summary'''.<br />
<br />
'''Minimum''' and '''maximum''' values are the '''whiskers''' of the '''box plot'''.<br />
<br />
The '''box''' spans first to third '''quartiles'''.<br />
<br />
The segment inside the box shows the '''median'''.<br />

| | '''Least Squares Linear Regression (LSLR)'''<br />
<br />
Changing an independent variable '''x''' changes the dependent variable '''y'''.<br />
<br />
'''LSLR''' predicts '''y''' based on '''x''' value.<br />
<br />
'''Least Squares Regression Line (LSRL)''' is also called the '''best fit line'''. <br />
<br />
It is given by '''y = b<sub>0</sub> + b<sub>1</sub>x'''.<br />
<br />
'''b<sub>0</sub>''', the '''y intercept''', is a '''constant'''.<br />
<br />
'''b<sub>1</sub>''', the '''slope''', is the '''regression coefficient'''.<br />
<br />
<br />
'''Coefficient of determination R<sup> </sup>squared'''<br />
<br />
'''R<sup> </sup>squared''' ranges from 0 to 1.<br />

|-<br />
| | Point to the red line that is drawn through some points.<br />
| | Note the red line that is drawn through some points in the '''Scatterplot'''.<br />
|-<br />
| | Point to length plotted on '''x-axis''', weight on '''y-axis'''.<br />
| | Length is plotted along '''x-axis''' and weight along '''y-axis'''.<br />
|-<br />
| | Point to equation is given in red, '''y= 0.08x-48.39'''.<br />
| | This is the '''best fit line''' that passes through as many points as possible.<br />
<br />
Its equation is given in red, '''y= 0.08x-48.39''', at the bottom.<br />
|-<br />
| | Point to '''R<sup>2'''</sup> value of 0.7722.<br />
| | Note that '''R<sup> </sup>squared''' value for this line is 0.7722 in the '''Statistics window.'''<br />
<br />
The closer '''R squared<sup> '''</sup>value is to 1, the better is the prediction of '''y''' from '''x''' by the equation.<br />
<br />
This ''' R<sup> </sup>squared''' value indicates good fit between the model and the actual data.<br />
|-<br />
| | Select other '''regression models''' to see effects on '''R<sup>2'''</sup>.<br />
| | Select other '''regression models''' to see effects on the '''R<sup> </sup>squared''' value.<br />
|-<br />
| | Point to the lower '''Residual Plot'''.<br />
| | The lower plot is the '''Residual Plot'''.<br />
<br />
It shows '''residuals''' along the '''y-axis''', '''length''' along the '''x-axis'''.<br />
<br />
'''Residuals '''are the differences between observed and predicted values of all points.<br />
<br />
Absence of '''U''' shape in the '''scatterplot''' means that '''linear regression''' is appropriate for these data.<br />

<br />
Point to equation '''y= 9.91x + 684.3'''.<br />
| | Observe that the '''best fit line''' and many '''statistics''' change.<br />
|-<br />
| | Point to '''r''', '''R<sup>2</sup> '''and '''rho (ρ)'''.<br />
| | The only statistics that remain the same are '''r''', '''R<sup> </sup>squared '''and '''rho (ρ)'''.<br />
<br />
Note that '''r''' and '''rho''' are greater than 0.8, indicating positive '''correlation'''.<br />
<br />
Weight increases as length increases for fish given '''feed C'''.<br />
<br />
The relationship is strong and well predicted by the '''best fit lines'''.<br />

|-<br />
| | Point at the line in the '''Scatterplot'''.<br />
| | If you choose '''x''' values below the '''x-intercept''' of the line, you will get negative values of '''y'''.<br />
<br />
To get logical predictions, we will enter '''x''' values above the '''x-intercept'''.<br />
|-<br />
| | In '''Symbolic Evaluation''', type in a value for '''x''' and press '''Enter'''.<br />
