In descriptive statistics, measurements such as the mean and standard deviation are stated as exact numbers. When you have collected data from a sample, you can use inferential statistics … Descriptive and inferential statistics are two broad categories in the field of statistics.In this blog post, I show you how both types of statistics are important for different purposes.

Interestingly, some of the statistical measures are similar, but the goals and methodologies are very different. Thus, the goals of inferential statistics are to estimate and/or predict. Descriptive statistics analyse data to help describe, show or summarise it in a meaningful way. Learn vocabulary, terms, and more with flashcards, games, and other study tools. While descriptive statistics are used to present raw data in an accurate way, inferential statistics are used to apply inferences derived from a data sample to the larger data population. For example, these procedures might be used to estimate the likelihood that the collected data occurred by chance (that is, to make probability predictions) It is saying that something works … A good example of inferential statistics in action is the prediction of the results of an election prior to the voting by means of polling. Descriptive statistics are designed to describe a sample, and is contrasted with Inferential Statistics which is designed to draw conclusions from the sample to the larger population. There are two types, called populations and samples. 2.)
