Descriptive statistics are useful because they allow you to understand a group of data much more. 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. The technique you use for inferential statistics is a bit different from the ones you use with descriptive statistics. Inferential statistics involves you taking several samples and trying to find one that accurately represents the population as a whole.
Descriptive and Inferential Statistics 3 The Department of Statistics and Data Sciences The University of Texas at Austin This tutorial describes the use of SPSS to obtain descriptive and inferential statistics. In the first section you will be introduced to procedures used to obtain several descriptive statistics. These are Descriptive Statistics and Inferential Statistics.
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.

For example we could calculate the mean and standard deviation of the exam marks for the 100 students and this could provide valuable information about this group of 100 students. In this type of statistics the data is summarised through the given observations.
The summarisation is one from a sample of population using parameters such as the mean or standard deviation. Descriptive statistics is a way to organise represent and describe a collection. Descriptive Statistics is a discipline 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. Descriptive Statistics collects organises analyzes and presents data in a meaningful way.
Descriptive and Inferential Statistics When analysing data such as the grades earned by 100 students it is possible to use both descriptive and inferential statistics in your analysis. Typically in most research conducted on groups of people you will use both descriptive and inferential statistics to.
