Unit And remember to use examples of descriptive statistics, not reasons to use descriptive statistics. Check your essay to make sure your Introduction Paragraph has a hook and a Thesis Statement. Check your essay to make sure it has three Examples Paragraphs. Check your essay to make sure it has a Conclusion Paragraph. Check your Conclusion Paragraph to make sure it has a Re-stated Thesis Statement and ends with something mildly witty or profound. Check your Re-stated Thesis Statement to make sure that it is ONE sentence that summarizes all three of your three examples.
It is quite hard to identify, whether the research relies on descriptive statistics or inferential statistics, as people usually, lacks knowledge about these two branches of statistics. As the name suggests, descriptive statistics is one which describes the population. On the other end, Inferential statistics is used to make the generalisation about the population based on the samples. So, there is a big difference between descriptive and inferential statistics, i. Basis for Comparison Descriptive Statistics Inferential Statistics Meaning Descriptive Statistics is that branch of statistics which is concerned with describing the population under study. Inferential Statistics is a type of statistics, that focuses on drawing conclusions about the population, on the basis of sample analysis and observation. What it does?
Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data. It is basically a collection of quantitative data. Descriptive Statistics : Descriptive statistics is a term given to the analysis of data that helps to describe, show and summarize data in a meaningful way. It is a simple way to describe our data. This type of statistics is applied on already known data. Inferential Statistics : In inferential statistics predictions are made by taking any group of data in which you are interested. It can be defined as a random sample of data taken from a population to describe and make inference about the population.
Statistics analysis provides you with the best information on methods to collect data. Data collection helps you make informed decisions in the workplace while rendering evidence that's beneficial in achieving your goals. The differences between descriptive and inferential statistics can assist you in delineating these concepts and how to calculate certain statistics. In this article, we will discuss what statistics is, what descriptive and inferential statistics is, the differences between these two concepts and frequently asked questions. Statistics is the method of learning from data, and it aids you in gathering and displaying your results.

However, the wikipedia page for statistical inference states:. For the most part, statistical inference makes propositions about populations, using data drawn from the population of interest via some form of random sampling.

Descriptive and Inferential Statistics
The field of statistics deals with collecting, exploring and presenting large amounts of data to discover underlying patterns and trends. Statistics is applied every day in many areas of our lives: business, industry, medicine and government—to facilitate making informed decisions in the presence of uncertainty and variation. For example, factory authorities use information from statistical quality control unit to know whether the length or weight of their products is within established standards. In this chapter, we present the basic steps of performing such statistical study which relies on employing a small, representative sample of products to make statistical inference of a wider population. We first describe methods of descriptive statistics which enable to capture the important features from sample data using tables, charts and graphs. Then, the described sampling distributions pave the way to inferential statistics, which allows us to draw conclusions about the whole population from which we took the sample.
Sign in. Statistics plays a main role in the field of research. It helps us in the collection, analysis and presentation of data. In this blog post we will try to learn about the two main branches of statistics that is descriptive and inferential statistics.

Together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data. Descriptive statistics are typically distinguished from inferential statistics. With descriptive statistics you are simply describing what is or what the data shows.
