# Statistics Formulas

## Statistics Formulas

Statistics are an integral part of Mathematics, and they are also a part of the Economics curriculum in some classes. The topic holds importance because it lays the foundation for upcoming classes and a number of courses after school. Students in school tend to not take this topic very seriously because there are other challenging concepts in the subject. However, this concept is also equally important for future classes and even examinations. Students start with learning the Statistics Formula, and it is not very challenging. Most schools rely on the recommended textbooks for teaching, but those might not always be enough. Relying on textbooks can be beneficial, but doing so exclusively may be detrimental.

### Statistical Formula

Students can learn about the Statistics Formula from textbooks, but having a supplementary learning option is always helpful. Learning online is the new trend, but the internet is full of sources, which makes it challenging to choose a reliable source. Learning online requires a reliable and trustworthy source. Extramarks is one of the most popular and reliable learning platforms. The study guides and learning modules on the website cover all the important topics, and explain them in great detail. The detailed analysis of the chapters and topics helps students retain the knowledge and perform better in examinations. The notes, along with the textbooks, cover all the topics holistically and make students less intimidated by concepts like the Statistics Formula. This reduces exam stress and helps students learn and retain all the concepts thoroughly.

What is statistics?

The study of data gathering, analysis, interpretation, presentation, and organisation is known as statistics. In other words, gathering and summarising data is a mathematical discipline. Additionally, statistics can be considered a subfield of applied mathematics. However, uncertainty and variation are two crucial and fundamental concepts in statistics. Only statistical analysis can determine the uncertainty and variation in various fields. The probability, which is a key concept in statistics, essentially determines these uncertainties.

Statistics are described as “Numerical statements of facts in any department of inquiry placed in relation to each other,” according to statistician Sir Arthur Lyon Bowley.

Statistics, according to Merriam-Webster, are “classified facts representing the conditions of a people in a state, especially facts that can be stated in numbers or any other tabular or classified arrangement.”

The measures of central tendency and dispersion are among the fundamental concepts in statistics. The mean, median, and mode are the central tendencies, and the variance and standard deviation are the dispersion.

The mean represents the mean of the observations. When observations are arranged in order, the median value is in the middle. The most frequent observations in a data set are identified by their mode.

The degree of spread among the data collections is measured by variation. Data dispersion from the mean is measured by the standard deviation. The variance is equal to the square of the standard deviation.

The formula in statistics

There are multiple Statistics Formula for students to learn. These formulas can be tough for the students to learn and understand in one sitting. Having a good learning source can help students have clear concepts, but choosing a good source can be challenging. Learning from the Extramarks platform allows students to focus on the Statistics Formula individually, and they can have better clarity before the exams. These challenging Statistics Formula are made easy with the interactive learning modules on the platform. These learning modules are curated by academic experts, and they are experienced in developing interactive study guides to make learning easier.

Students can access the entire Statistics Formula Sheet on the Extramarks platform.

### Solved Example

Solved examples are a good option for students who want to learn with the help of applications of the Statistics Formula. These solved examples are found in the textbooks recommended by the school and the education board. Students can learn and then practise with the help of the solved examples and textbook questions.
