Statistic project

Posted by ricardogm on 17th May 2019

1. First of all, we are going to organize the teams for the statistic project. Tell me the members of each team and a name for it.

2. Now a little information about the project. It will be a Word document, or Powerpoint,  with, at least, this structure:

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.

3. Remember, we are going to study the relationship between two variables, posibly with a survey. You need al least 30 data points. Less than that, it’s anecdotal.

4. And we are going to learn to use geogebra in statistics, today with one variable, next friday with two. Pay attention

Ex.1 isolated data:

The number of occupants in passing cars are counted. The results are:

1 2 1 4 3 1 2 1 5 4
1 1 1 2 1 3 1 4 1 1
1 2 1 1 1 2 1 1 4 2
2 2 1 2 1 3 2 1 2 1

Ex. 2

A class of 40 students took a mock exam in maths. They were given percentage marks as follows:

73, 45, 62, 34, 59, 20, 48, 50, 78, 38, 52, 91, 57, 82, 46, 51, 62, 58, 39, 50, 72, 73, 63, 52, 41, 37, 28, 46, 71, 75, 36, 28, 44, 90, 51, 28, 60, 18, 47, 40.

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