DRAWING CONCLUSIONS

As it was explained in the previous entry, "CURIOUS NBA STATISTICS", statistics is "a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data".

The application of statistical procedures dates back to the year 3050 before Christ, when a register of population and wealth was carried out in Egypt in order to prepare the construction of the pyramids. Later, Egyptians, Greeks and Romans also carried out some censuses with tributary, social and military purposes, and much later, in the sixteenth century, statistical inventories were published in Germany, Italy and France.

Although initially the statistics arises from the elaboration of censuses, its application is currently extended to numerous fields, such as agriculture, biology, politics, psychology, education and so on. However, there are many people who for lack of critical sense of a statistical nature are very easily impressed by surprising statistical coincidences that have nothing surprising. So, for this reason, it is quite important to draw conclusions before giving final conclusions.

According to the previous reasoning, it will be exposed some statistical examples of not giving premature conclusions and I would like you to share your opinion, in the comments section, about that non statistical relation.

Statistics show that almost all traffic accidents occur between vehicles that travel at moderate speed. However, very few of that traffic accidents occur at more than 150 km per hour. Does this mean that it is safer to drive at high speed?

A recent psychopedagogical study has shown that children with large feet can read better than those with small feet. Is foot size a good tool to measure the ability of reading in children?

In 1984 many more people died in Spain due to traffic accidents than in 1960. Is this enough to affirm that it was more dangerous to travel in 1984 than in 1960?

COUNTRIES´ SIZE

We have spent our entire lives looking at the wrong map: the Mercator projection ,which is the most frequently one used on the world maps. It enormously distorts the size of the countries or territories closest to the poles (essentially, those that are in the northern hemisphere) and, in comparison with it, it minimizes those that are closed to Ecuador, especially, South America and Africa. That explains why we have been mistakenly thinking that Greenland is similar in size to Africa, when in fact it is fifteen times smaller! [ Mercator projection of the world ] Moreover, a new projection to measure the countries was used at the beginning of the eighties in order to solve Mercator projection´s problematic: Gall–Peters projection . However, it was a terrible idea because it incurred a series of topographical errors. [ The Gall–Peters projection of the world map ] This distorting effect is inevitable due to the Earth is a sphere and not a disk, as some people believe

PLAYFUL ACTIVITIES TO WORK THE CONCEPT OF MEASUREMENT IN CLASS

Sometimes, mathematics can be difficult to understand by students due to the complexity of it, and also this problematic can be presented in the concept of measurement. For this reason, I would like to expose three useful and playful activities that can deal with this situation. 1. MEASUREMENT LADDER The concept of metric unit change is a problematic issue for students because they are not aware of what the process itself supposed. As a result of this, they are not able to identify when a multiplication or division is involved in the metric unit change process. MEASUREMENT LADDER is a playful technique that is oriented to solve this problematic issue. The simile of a ladder will be used to explain the jump from one unit of length (mass or capacity) to another. So, when we would go up from meters to kilometers we have to divide by 10 for each step we climb and on the other hand, when we would go down, we carry out the same process but multiplying by 10. To make even more p

THE EFFECT OF MEASUREMENT IN MUSIC

Does it exist any connection between mathematics and music?, and if so, how does it affect us? As surreal as it turns out, the relationship exists. To understand it, we have to go back to ancient Greece, specifically Pythagoras. He was who discovered the importance of numbers in music and the relationship between this discipline and mathematics. The word mathematics comes from the Greek word μάθημα, which means "knowledge". Pythagoras and his followers divided this science into four areas: arithmetic, geometry, astronomy and MUSIC . For this reason, we could affirm that the Pythagorean philosophers were the ones who laid the foundations of our current music. Nowadays, mathematics has to do even more with acoustics than with composition and the use of mathematics in composition is historically limited to the simplest operations of measuring and counting. As a result of that, we could affirm that we feel emotions and feelings through songs because of their mathematical
