Descriptive statistics describe what is going on in a population or data set. Inferential statistics use samples to draw inferences about larger populations.
Descriptive Statistics collects organises analyzes and presents data in a meaningful way.
What is descriptive and inferential statistics. Descriptive statistics use summary statistics graphs and tables to describe a data set. This is useful for helping us gain a quick and easy understanding of a data set without pouring over all of the individual data values. Inferential statistics use samples to draw inferences about larger populations.
Descriptive statistics describe what is going on in a population or data set. Inferential statistics by contrast allow scientists to take findings from a sample group and generalize them to a larger population. The two types of statistics have some important differences.
Descriptive statistics is the term given to the analysis of data that helps describe show or summarize data in a meaningful way such that for example patterns might emerge from the data. Descriptive statistics do not however allow us to make conclusions beyond the data we have analysed or reach conclusions regarding any hypotheses we might have made. Both descriptive and inferential statistics have their benefits and shortcomings.
Descriptive statistics are great for a small population. You can accurately produce numbers for the population without worrying about being off or making any errors but you cant make any conclusions that go beyond the population that you have. In brief Descriptive statistics analyze the big data with the help of charts and tables.
It never attempts to use a sample to reach a conclusion. On the contrary in Inferential statistics researchers test the hypothesis. Heshe studies the sample and reaches the conclusions of the population.
This blog is based on Descriptive and Inferential statistics. The primary difference between descriptive and inferential statistics is that descriptive statistics measure for definitive measurement while inferential statistics note the margin of error of research performed. In Maths Statistics is a method of interpreting analysing and summarising the data.
Hence the types of statistics are categorised based on these features. Descriptive and inferential statistics. Based on the representation of data such as using pie charts bar graphs or tables we analyse and interpret it.
Difference between descriptive and inferential statistics According to Houser 2009 descriptive statistics are the statistical steps that are followed to describe the totality of study. He goes on to say that the data that are used on study could be gathered from either a. Descriptive and inferential statistics each give different insights into the nature of the data gathered.
One alone cannot give the whole picture. Together they provide a powerful tool for both description and prediction. Categorizing Statistics The study of statistics can be categorized into two main branches.
These branches are descriptive statistics and inferential statistics. Whats the difference between descriptive and inferential statistics. Descriptive statistics summarize the characteristics of a data set.
Inferential statistics allow you to test a hypothesis or assess whether your data is generalizable to the broader population. Whats the difference between descriptive and inferential statistics. Descriptive statistics summarize the characteristics of a data set.

That focuses on drawing conclusions about the population on the basis of sample analysis and observation. Descriptive Statistics collects organises analyzes and presents data in a meaningful way. While descriptive statistics are a way to review exact numbers inferential statistics allows for generalizations to be made.
Rather than taking a sample and applying it to a whole population as a specific number inferential statistics provides conclusions and generalizations. When analysing data such as the grades earned by 100 studentsit is possible to use both descriptive and inferential statisticsin your analysis. Typically in most research conducted ongroups of people you will use both descriptive and inferential statistics toanalyse your results and draw conclusions.
So what are descriptive andinferential statistics. And what are their differences. This video tutorial provides an introduction into descriptive statistics and inferential statisticsMy Website.
Descriptive statistics goal is to make the data become meaningful and easier to understand. Meanwhile inferential statistics is concerned to make a conclusion create a prediction or testing a hypothesis about a population from sample. To achieve the descriptive statistics purpose there are two form of analyses which we could use.
