What Is Inferential Statistical Analysis. Inferential statistics draws alidv inferences about a population based on an analysis of a representative sample of that population. In such analyses there is a specific focus on the independent variables and you want to make sure you have an interpretable model. For instance your example on a study to examine whether smoking causes lung cancer is inferential. Inferential statistics is when you are trying to understand what causes a certain outcome.
In some instances its impossible to get data from an entire population or its too expensive. Inferential statistics provides a way to draw conclusions about broad groups or populations based on a set of sample data. Inferential statistics draws alidv inferences about a population based on an analysis of a representative sample of that population. A large number of statistical tests can be used for this purpose. The results of such an analysis are generalized to the larger population from which the sample originates in order to make assumptions or predictions about the population in general. Inferential statistics focus on analyzing sample data to infer the population.

Visualize your data and make informed decisions quickly. In a nutshell inferential statistics uses a small sample of data to draw inferences about the larger population that the sample came from. The process of inferring insights from a sample data is called Inferential Statistics. In some instances its impossible to get data from an entire population or its too expensive. Inferential statistics is one of the two statistical methods employed to analyze data along with descriptive statistics. Inferential statistical analysis involves objectively and quantitatively summarizing the data determining which data patterns are significant and making inferential statements about system performance.
