While mastering more complex math concepts (such as calculus and beyond) expands your toolbox and teaches you how to handle problems, it can also be a roadblock that prevents you from moving forward on your path to becoming a data analyst.
Here are the three important branches of Maths which will help you become a data analyst.
The branch of mathematics known as statistics deals with gathering, analysing, presenting, and data interpretation. Despite the fact that they produce different results for different issues, statistics and probability are related and frequently taught together. The foundations for comprehending what data sets tell us are provided by statistics, which is the main dish of data analysis.
Measures of core tendency and variables of variability, which gauge various facets of a population, are further divisions of descriptive statistics that describe the features of a population.
Probability is the study of the likelihood that something will occur, and it is crucial for arriving at findings that can aid in making decisions in ambiguous circumstances. While statistics and probability are related and frequently combined for study, the two are used to reach different results.
Finding the possibility that a recession will happen, the likelihood that an illness is connected to the frequency of a gene, or even the likelihood that a visitor to a website will sign up for its newsletter are just a few of the numerous practical applications of probability in various industries.
The branch of mathematics known as linear algebra is used to solve linear equations with unknown values and serves as the basis for understanding machine learning.
While machine learning may not fall under the purview of a general data analyst's day-to-day tasks, both data pretreatment and data transformation involve the application of linear algebra's core ideas. Furthermore, learning linear algebra teaches you how to reason logically through a series of steps, which is helpful when conducting analysis that focuses on providing an answer to a particular issue or resolving a particular problem.
Vectors, matrix transformations, spaces, and different coordinate systems are all concepts in linear algebra. In data analysis, vectors can be used to determine how dissimilar a prediction from a data collection is from the expected result following data transformation. When data is transformed, it can be represented geometrically in a 2D and 3D space by using matrix transformations to change one vector into another. To guarantee that data is properly represented, other coordinate systems can be employed in data analysis to alter the visual representation of information.
