As the name suggests descriptive statistics is one which describes the population. Typically in most research conducted ongroups of people you will use both descriptive and inferential statistics toanalyse your results and draw conclusions.

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. 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. It gives information about raw data which describes the data in some manner.
It makes inference about population using data drawn from the population. It helps in organizing analyzing and to present data in a meaningful manner. Both descriptive and inferential statistics help make sense out of row after row of data.
Use descriptive statistics to summarize and graph the data for a group that you choose. This process allows you to understand that specific set of observations. Descriptive statistics describe a sample.
Descriptive statistics are just descriptive. They do not involve generalizing beyond the data at hand. Generalizing from our data to another set of cases is the business of inferential statistics which youll be studying in another section.
Inferential statistics involves studying a sample of data. The term implies that information has to be inferred from the presented data. A sample of the data is considered studied and analyzed.
Unlike descriptive statistics this data analysis can extend to a similar larger group and can be visually represented by means of graphic elements. 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. 11 Descriptive Statistics A common first step in data analysis is to summarize information about variables in your dataset such as the averages and variances of variables. Several summary or descriptive statistics are available under the Descriptives option available from the Analyze and Descriptive Statistics menus.
Statistics is a division of mathematics that centers on the collection and evaluation of data which can be drawn upon to make conclusions Aron Aron Coups 2006 2. Two branches of statistics exist including descriptive and inferential domains. Extrapolation beyond the data is where the real difference emerges.
While descriptive statistics describe data inferential statistics allows you to make predictions from data. Below is an in-depth analysis of their differences. Outlines the features of populations and samples.
Use samples to make generalizations about larger populations. We have seen that descriptive statistics provide information about our immediate group of data. 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.
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. All statistical methods can be classified as descriptive or inferential statistics. Descriptive statistics refers to analysis of data in order to summarize the important characteristics of data in a meaningful way.
However descriptive statistics does not allow us to make any conclusions beyond the data. Expressive insights just measure the gathering you relegate for the trial implying that you choose to not factor in factors. Inferential insights represent examining blunders which may prompt extra tests to be led on a bigger populace relying upon how much data is required.
