What Is The Difference Between Descriptive And Inferential Statistics

Rather than being used to describe the data itself inferential metrics are used to reveal correlation proportion or other relationships present in the data.

The two types of statistics have some important differences. 21 08 2020 statistics is a branch of mathematics dealing with the collection analysis interpretation and presentation of masses of numerical data. Inferential statistics makes inferences about a larger population. The term implies that information has to be inferred from the presented data.

Inferential statistics involves studying a sample of data. Unlike descriptive statistics this data analysis can extend to a similar larger group and can be visually represented by means of graphic elements. Descriptive statistics make only summarization of the properties of the sample from which data were acquired but in inferential statistics the measure from the sample is used to infer properties of the population. A sample of the data is considered studied and analyzed.

Descriptive statistics use summary statistics graphs and tables to describe a data set. On the contrary in inferential statistics researchers test the hypothesis. Inferential statistics allow you to use data to make predictions or inferences based upon the data. Difference between descriptive and inferential statistics last updated.

The primary difference between descriptive and inferential statistics is that descriptive statistics is all about illustrating your current dataset whereas inferential statistics focuses on making assumptions on the additional population that is beyond the dataset under study. 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. In inferential statistics the parameters were obtained from a sample but not the whole population.

These are descriptive statistics and inferential statistics. Inferential statistics by contrast allow scientists to take findings from a sample group and generalize them to a larger population. Descriptive and inferential statistics are two broad categories in the field of statistics. What are inferential statistics.

Descriptive statistics describe what is going on in a population or data set. Inferential statistics use samples to draw inferences about. Therefore always some uncertainty exists compared to the real values. This is in clear contrast to descriptive statistics.

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.
