Researches about theory

1_R. Give your best description of the many reaching out of statistics, in its various form, as a branch of math (Probability theory, etc.), as a set of methodologies used in many other disciplines, as an essential tool to deal with any sort of data, make reports and provide governance tools. Discuss whether it can be considered a “science” and what is the “scientific method” (what is a “theory” and what is a “hypothesis”). What is the role of Statistics in Math and Science?

Applications

1_A. Create – in both languages C# and VB.NET – a program which does the following simple tasks to get acquainted with the tool:

– when a button is pressed some text appears in a richtexbox on the startup form
– when another button is pressed animate one or more balls (possibly of different colors and sizes) within a rectangle

Application 1_A


This video showing how application 1_A works (in both C # and vb-net).

The form is composed by:

  • two buttons;
  • a label;
  • a comboBox;
  • a richTextBox;
  • a timer;
  • two pictureBox.

Pressing the “Text” button will make some text appear in the richTextBox.

Pressing the “Start/Stop” will set the timer property enabled to true or false; with each tick of timer1 the ball moves in two directions until it meets an edge of the rectangle. As we can see in the video, ball is able to move at 5 different speeds, which will set its speed to a defined value.

Research about theory 1_R


Statistics is a mathematical science about the collection, analysis, interpretation or explanation, and presentation of data. It applies to a wide variety of academic disciplines, from the physical and social sciences to the humanities. Statistics are also used for making informed decisions. Statistical methods can be used to summarize or describe a collection of data. In addition, patterns in the data may be modelled in a way that accounts for randomness and uncertainty in the observations, and then used to draw inferences about the process or population being studied.
