Bidimensional statistics study, correlation, etc.

Posted by ricardogm on May 17th, 2018

Hi

Today you are going to decide the topic for your statistic study. It has to have two variables, and the goal is to check if there’s any correlation between the two characteristics. So have a meeting with your team partners and choose the idea for your study. The minimum requirements for the survey are:

Two variables (quantitative, of course).

  • Minimum number of data for the survey: 30 individuals. 
  • The study should be something about La Luz or Avilés, or our school.
  •  Nobody (people, animals or plants) should be harmed or offended in the making of this study.
  • The study should be written in a powerpoint or word file.
  • It has to have graphs and calculations.(You can use Geogebra for that)
  • It must have:
    • A frontpage with your names and the title.
    • An introduction explaining the goal of the study.
    • All the data in one or several tables.
    • Graphs and images.
    • Calculations.
    • Conclusion.
  • The deadline for all this is june the 4th.

I don’t mind if the variables you choose are funny or absurd, as long as they don’t offend anyone. In fact, a bit of fun is something to be thankfull. Think about it and send me a mail with your ideas.

As an example, I’m showing you how to use geogebra to work with two statistical variables, using examples of your book. Pay attention.

Introducción a la derivada

Posted by ricardogm on May 14th, 2018

 

Muy buenas

Hoy os presentamos este concepto tan importante en el cálculo: la derivada de una función. Las dos construcciones que siguen tratan de ilustrar el concepto:

Efectivamente, la derivada no es más que la medida de la pendiente. Veamos otra más cercana a la definición que usaremos:

Y seguimos haciendo ejercicios de límites. Podemos empezar, por ejemplo, por el 19, ayudándonos de Geogebra para representar.

Statistics with Excel and Geogebra

Posted by ricardogm on May 3rd, 2018

Hi

0. First things first:

3. We are going to learn to use excel and geogebra in our statistical studies. I’m going to give you some instructions (copy them in your notebook) and some exercises to solve (from your textbook). Pay attention. Please send me an excel document and a geogebra file at the end of the class.

Appendix: some useful links:

1. estadistica-excel.pdf (This is a tutorial)

The histograms in excel are poorly implemented, in my opinion. Geogebra does a much better work. Follow the instructions in this example:

Math poems

Posted by ricardogm on April 23rd, 2018

Sole Soul

I

once

thought we

were one, that

you were my soul mate

until I realized that our

joint passion for a specific salt water flatfish

cooked in meuniere sauce was not sufficient to maintain a long lasting relationship

Copyright © D.W. Rodgers | Year Posted 2018

Why is the poem above a math poem? It’s a difficult question…

Zero, the hero

Put one, before, nine numbers of zero,

and take one off, have nine numbers of nine.

Grows a number ten times, zero, the hero.

Put one, before, nine numbers of zero.

Centre of integers, is the number zero,

to the left and right, may go endless, fine.

Put one, before nine numbers of zero

and take one off, have nine numbers of nine.

************

Zero and one make the computer byte.

Zero is the dark and one is bright.

That is what the cycle of day night,

Zero and one make the computer byte.

From the zero and one, gets its life,

on binary system, computer does thrive.

Zero and one make the computer byte.

Zero is the dark and one is bright.

1000000000-1 = 999999999

Funciones a trozos y otras

Posted by ricardogm on April 22nd, 2018

Muy buenas

1. Hoy vamos en primer lugar a aprender a crear funciones a trozos en geogebra. Para las funciones a trozos os recuerdo que hay que utilizar el comando Función, de esta manera:

Función[ <Función>, <Valor inicial>, <Valor final> ].

Pondremos los valores para cada tramo y listo. Prestad atención a la explicación.

Con esta técnica haremos los ejercicios 12 y 13 de la p. 268. Podéis hacer todos los apartados en un sólo archivo, ocultando las funciones sucesivamente. Copiad también las gráficas en la libreta.

2. Ahora pasaremos a la página 253 del libro, y resolveremos en la libreta los ejercicios 1 y 2. Podéis ayudaros con Geogebra. Basta con utilizarlo para representar las funciones que queráis. Me enviáis el archivo (usad el truco de ocultar para no borrar las funciones)

Y como es Día del Libro, homenaje a Forges:
