Inferential statistics focus on how to generalize the statistics obtained from a sample as accurately as possible to represent the population. Statistics is concerned with developing and studying different methods for collecting, analyzing and presenting the empirical data.. Inferential Statistics Descriptive statistics are used to describe quantitative data sets whereas inferential statistics are utilized to draw quantitative conclusions (i.e., … While descriptive statistics summarize the characteristics of a data set, inferential statistics help you come to conclusions and make predictions based on your data..

Descriptive statistics are likely to be 100% accurate because there are no assumptions being made about the raw data that is used. Inferential statistics measure relations and effect.

What are inferential statistics? Descriptive Statistics vs. Inferential Statistics Lecture Slides are screen-captured images of important points in the lecture. We want to make a quantitative research find out if there is a relationship between the nutritional status of a child and the mathematical score obtained. In contrast, inferential statistics always make inferences about a large population based on a smaller sample. We earlier mentioned a situation where statistician has to stand at the entrance of a mall to carry out a survey.

Descriptive statistics does not allow drawing conclusions beyond the information we already have or reaching verdicts regarding hypotheses we may have. Some examples of inferential statistics commonly used in survey data analysis are t-tests that compare group averages, analyses of variance, correlation and regression, and advanced techniques such as factor analysis, cluster analysis and multidimensional modeling procedures. Descriptive statistics: As the name implies, descriptive statistics focus on providing you with a description that illuminates some characteristic of your numerical dataset. Descriptive statistics uses the data to provide descriptions of the population, either through numerical calculations or graphs or tables. Marcelina763 TEACHER.

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. Revised on January 21, 2021. The measures of descriptive statistics obtained from the analysis of the sample are known as parameters when applied to the population, and they represent the whole population. Flashcards.
