As a whole, statistics can be divided into two main categories. They are descriptive and inferential. They are different, but both are important in the field of the Social Sciences. Both descriptive and inferential statistics can help Social Scientists get a snapshot of either a certain population or sample of a population. The crux of the differences between descriptive and inferential statistics are how they are defined, how they are applied by Social Scientists and the amount of care a Social Scientist must take in using them.

Descriptive statistics has been defined by C. Urdan (2010) as “statistics used to describe the characteristics of a distribution of scores" (p. 10). An addition to that definition is the fact that descriptive statistics “summarize the data with the purpose of describing what occurred in the sample” (Allua & Thompson, 2009). Descriptive statistics is literally just the numbers for that population or sample. One example of this is saying “suicide is a big factor [in premature deaths of people with mental illnesses], accounting for 30 to 40 percent of early deaths. But 60 percent die of preventable or treatable conditions” (Garey, 2013). As you can see, descriptive statistics draw no conclusions about the data collected, it is just the what is collected.

Inferential statistics are “statistics, derived from sample data, that are used to make inferences about the population from which the sample was drawn” (Urdan, 2010, p. 11). Inferential statistics “refer to the use of sample data to reach some conclusions (i.e. makes some inferences) about the characteristics of the larger population that the sample is supposed to represent" (Urdan, 2010, p. 2). An example of an inferential statistic would be saying "9...

... Scientists and the amount of care a Social Scientist needs to take in order to properly utilize them. It is important to know the distinctions between descriptive and inferential statistics because without knowing the differences, a Social Scientist could run the risk of improper use of their collected data. Proper use of data is key to being a worthwhile Social Scientist and helps to advance the field of Social science.
