Practicing for your project

Posted by ricardogm on 24th May 2018

 

1. First of all, you are going to correct exercise 2 from the worksheet using geogebra. Send me the file.

2. Now we are going to practice a little about our statistics project. Use the last two problems from the worksheet as examples, and the goal is to use them the same way you are going to treat your data. For each example you should send me a Word document, or Powerpoint, but with the same structure as the final project. At the very least it should have:

1. Frontpage with your names and the title of the project.

2. Introduction (in another page). Explaining the goal of the project, what you want to know, how you got the data, etc.

3. Another page with the data, in table form.

4. Another page with graphics.

5. One more with all the calculations.

6. And one with the final conclusions.

As a bonus, this image links to some examples of terrible powerpoint design:

Bidimensional statistics study, correlation, etc.

Posted by ricardogm on 17th May 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 14th May 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 3rd May 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:
