Descriptive and Inferential Statistics

What is the difference between descriptive and inferential statistics?



Both descriptive and inferential statistics are both used in analysis of numeric data. Descriptive statistics are used to reveal patterns through this analysis. Descriptive statistics describe the group they belong to. Examples of descriptive statistics are frequency counts, ranges, means, median scores, modes, and standard deviations. A specific example would be: “The class had an average score of 90.2%”. Inferential statistics are used to draw conclusions and make predictions through this analysis. Inferential is about a larger group. Examples of inferential statistics are experiments, probability, population, sampling, and matching. A specific example is: “65% of Americans approve of the bill.”
