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. 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 allow you to test a hypothesis or assess whether your data is generalizable to the broader population.
Difference between descriptive and inferential statistic. In summary the difference between descriptive and inferential statistics can be described as follows. 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. Descriptive Statistics Inferential Statistics. 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. It allows us to compare data make hypothesis and predictions.
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 describes a situation while inferential statistics explains the likelihood of the occurrence of an event. Descriptive statistics explains the data which is already known to summarise sample. As you can see the difference between descriptive and inferential statistics lies in the process as much as it does the statistics that you report.
For descriptive statistics we choose a group that we want to describe and then measure all subjects in that group. 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. Inferential statistics generalizes the statistics obtained from a sample to the general population to which the sample belongs.
The measures of the population are termed as parameters. 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. The difference between descriptive and inferential statistics is the way it looks at data.
The descriptive statistics describe the population whereas inferential statistics take a sample of people for a particular pattern and generalizes it with the whole lot. 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. Descriptive vs inferential statistics. First lets discuss the basic differences between these two types of analysis.
The difference of goal. Descriptive statistics and inferential statistics has totally different purpose. Descriptive statistics goal is to make the data become meaningful and easier to understand.
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. In the inferential statistic one can get the outcome of the analysis by using the sample and can aggregate it to the whole population that the sample represents. Descriptive statistics give the information of a group we are studying.
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. What is the role of inferential statistics.

Moavia Aslam AMM 2B 1172016 2. To understand the simple difference between descriptive and inferential statistics all you need to remember is that descriptive statistics summarize your current dataset and inferential statistics aim to draw conclusions about an additional population outside of your dataset. Perhaps these concepts are most easily explained with some examples.
When we use descriptive statistics it is useful to summarize our group of data using a combination of tabulated description ie tables graphical description ie graphs and charts and statistical commentary ie a discussion of the results. We have seen that descriptive statistics provide information about our.
