Risk analysis is a systematic process of identifying, assessing, and managing potential risk factors. Its main parts include risk assessment, risk management, and risk information communication.
It’s the part of a fraction in math, referring to the number written above the fraction line, usually an integer.
Fractal geometry is a branch of geometry that studies irregular geometric shapes. Its main focus is on describing and studying complex structures that are self-similar (parts resemble the whole) and have non-integer dimensions, which is why it’s often called 'the geometry of nature'.
Fractal is a geometric term officially proposed by mathematician Benoît B. Mandelbrot in 1975. It refers to a complex geometric shape that has self-similarity and usually a non-integer (fractional) dimension. It's considered a mathematical language for describing irregular forms in nature and is also called 'the geometry of nature.'
Analyzing data usually refers to using statistical methods to organize, study, and summarize a large amount of collected data, extracting useful information and forming conclusions to help with business or operational decisions. In English, it's commonly called Data Analysis or Analyze Data.
A fraction line is the horizontal line drawn between the numerator and the denominator. Sometimes, this line can also appear as a slash '/', with the numerator on the left and the denominator on the right.
