The two broad categories of summarizing and analyzing data are referred to as descriptive and inferential statistics. You could probably tell by the name what these two types represent. While descriptive statistics summarize the characteristics of a data set, inferential statistics help you come to conclusions and make predictions based on your data.. Both descriptive and inferential statistics rely on the same set of data. Descriptive statistics play a central role in putting inferential statistical analyses into context.Every research study that uses inferential statistics should have a section presenting descriptive statistics related to the sample.The p-values associated with treatment effects should be interpreted within the context of the measures of descriptive statistics generated in the inferential analyses. It summarises the data through numbers and graphs. In this course, you will learn how to organize and summarize data. Chapter 2: LO2-1 Frequency Table; LO2-2 Chart Types. It makes inference about population using data drawn from the population. While statistical inferencing aims to draw conclusions for the population by analyzing the sample. Are descriptive statistics and inferential statistics one and the same? Descriptive statistics and inferential statistics has totally different purpose. It allows us to compare data, make hypothesis and predictions. An introduction to inferential statistics. 1C. Descriptive Statistics Descriptive statistics are numbers that are used to summarize and describe data. Inferential statistics are statistics methods that analyze a sample which is a subset of a population to make inferences and predictions about a population.
