To learn statistics from a holistic point of view, students should have the knowledge of two branches of statistics. It is essential to learn and understand the whole idea of statistical analysis. The two branches of statistics are descriptive and inferential statistics. These branches of statistics follow a particular scientific approach that makes them equally important to every statistical student. Today, in this blog, we will discuss the branches of
statistics. Before we get started, let’s have a quick look at what statistics is? Statistics is the main branch of mathematics. Used to perform different operations, i.e., Data collection, organization, analysis, and so on. In other words, statistics is a form of mathematical analysis that uses quantitative models to give a set of experimental data or studies of real life. Statistics examine the methodology for collecting, reviewing, analyzing, and making data conclusions. Some statistical measures include the following:
Now, let’s move towards discussing the two branches of statistics, Descriptive and Inferential Statistics. Descriptive StatisticsDescriptive statistics is the first part of statistics that deals with the collection of data. People think it is too easy, but it is not that easy. The statisticians need to be aware of the design and experiments. They also need to select the correct focus group and keep away from biases. On the contrary, Descriptive statistics are used to do various kinds of analysis on different studies. Example of Descriptive StatisticsThe average score of the college students in the math test.The average age of the people who voted for the winning candidate in the last election.The average length of the statistics book. Descriptive statistics have two parts;
To help understand the analyzed data, the tendency measures and variability measures use tables, general discussions, and charts. Measures of Central TendencyCentral tendency measures specifically help statisticians evaluate the distribution center of values. These tendency measures are: Mean Mean is a conventional method used to describe the central tendency. Typically, calculate the average of values, count all values, and then divide them with the number of available values. Formula of Mean m= Sum of the terms/numbers of terms For Example: Calculate the mean of the following data:10, 10, 40, 50, 20 Median It is the result that is in the middle of a set of values. An easy way to calculate the median is to edit the results in numerical journals and locate the result that is in the center of the distributed sample. Formula of Median To solve the median, there are two formulas;
(n+1 / 2)th observation
median=(n/2)th + (n/2+ 1)th observation / 2 For Example 1: Find the median of 4, 1, and 7. For Example 2: Find the median of the data 2, 4, 6, 8, 10, 12. Mode The mode is the frequently occurring value in the given data set. For Example: Find the mode of the given data,4, 2, 4, 3, 2, 2 Measures of VariabilityThe variability measure helps statisticians to analyze the distribution that is spreading from a specific data set. Some of the variables of variability include quartiles, ranges, variances, and standard deviation. Also Read
Inferential StatisticsInference statistics are techniques that enable statisticians to use the information collected from the sample to conclude, bring decisions, or predict a defined population. Inference statistics often speak in terms of probability by using descriptive statistics. Besides, a statistician uses these techniques for data analysis, drafting, and making conclusions from limited information. That is obtained by taking samples and testing how reliable they are. Most future predictions and generalizations on a smaller specimen population study are in the inference statistics’ scope. Besides, most social sciences experiments deal with studying a small sample population that helps determine the community’s behavior. Designing a real experiment, the researcher can bring conclusions relevant to his study. When making conclusions, it should be cautious not to draw wrongly or biased. Example of Inferential Statistics Different types of inferential statistics include:

Frequently Asked QuestionsWhat are the branches of demography in statistics?Demography refers to the study of population, and it focuses on five aspects, which are as follows; What is the difference between the two branches of statistics?Statistics is divided into two major parts: descriptive and inferential statistics. Descriptive statistics represent what is going on in a population or data set. On the contrary, inferential statistics enables the statisticians to take findings from a sample group and generalize them to a larger population. Which branch of statistics deals with the techniques that are used to collect organize and present the data?Answer: The branch of statistics that involves organizing, displaying, and describing data is Descriptive Statistics. Explanation: Descriptive statistics aims at describing the data features and providing summaries of the whole or sample population of data collected.
What statistics are used to organize and present a set of data?Descriptive statistics are procedures used to summarize, organize, and make sense of a set of scores or observations. Descriptive statistics are typically presented graphically, in tabular form (in tables), or as summary statistics (single values).
What are the branch of statistics?There are three real branches of statistics: data collection, descriptive statistics and inferential statistics.
Which branch of statistics involves collecting organizing and summarizing data?Descriptive statistics is the branch of statistics that involves the organization, summarization and display of data.
