# Is learning Statistics Essential for data science beginners?

·

Statistics is an essential component of any data science project. Data scientists must grasp the core concepts of descriptive statistics and probability theory, including probability distribution, statistical significance, testing of hypotheses, and regression.

Statistics and Data science:

The foundation of machine learning and data science is entirely based on statistics. As a result, it is critical to thoroughly understand the fundamentals of statistics to solve real-world problems.

If you've never worked with statistics before, we'll walk you through the concepts you need to know to succeed in data science. To know what to apply where, you must be at ease while learning mathematical equations, statistical formulas, and theories. It is difficult, to be sure, but it is worthwhile to learn the subject.

From exploratory data analysis to hypothesis testing, statistics play a critical role in solving many problems across various industries and sectors, particularly for data scientists.

Basic Statistics Terminologies:

Certain terminologies must be understood in order to master statistical tools for data science. They are as follows:

Population: A population is a set of resources from which we can collect data. Sample: A sample is a subset of the population that is used for data sampling and inferential statistics to predict the outcome. Variable: A variable can be a number, a characteristic, or a quantifiable quantity. It is also known as a data point. Probability Distribution: A probability distribution is a mathematical concept that primarily gives the probabilities of occurrence of various possible outcomes for a statistical experiment. Statistical or population parameter: A statistical or population parameter is a quantity that aids in indexing a family of probability distributions, such as a population's mean, median, or mode.

Types of Statistics:

Descriptive statistics: Descriptive statistics is a concept that allows us to analyze and summarise data and organize it in the form of numbers, graphs, bar plots, histograms, pie charts, and so on. Descriptive statistics are simply methods for describing existing data. It converts raw observations into meaningful data that can be interpreted and used further. When it comes to learning descriptive statistics, concepts like standard deviation and central tendency are widely used around the world.

Inferential Statistics – On the other hand, inferential statistics is an important concept that deals with drawing conclusions based on small samples taken from the entire population. For example, during an election poll, people frequently want to predict the exit poll results, so they will conduct a survey in various parts of the state or country and record their opinion. They tend to draw conclusions and make inferences based on the information they have gathered to predict results for the entire population.

Conclusion:

Statistics is one of the most important tools in Data Science. It is considered as the grammar of science, especially in computer and data science.
