Peer review does the same thing for science that the "inspected by #7" sticker does for your t-shirt: provides assurance that someone who knows what they're doing has double-checked it.

In science, peer review typically works something like this: A group of scientists completes a study and writes it up in the form of an article. They submit it to a journal for publication. The journal's editors send the article to several other scientists who work in the same field (i.e., the "peers" of peer review). Those reviewers provide feedback on the article and tell the editor whether or not they think the study is of high enough quality to be published. The authors may then revise their article and resubmit it for consideration.

Peer review and publication are time-consuming, frequently involving more than a year between submission and publication. Peer-reviewed articles provide a trusted form of scientific communication.

I included mixtapes if the artist was just short of the 35,000 words. Quite a few rappers don’t have enough official material to be included (e.g., Biggie, Kendrick Lamar). I used a research methodology called token analysis to determine each artist’s vocabulary. Dictionary of Statistics. Types of Statistical Tests. After looking at the distribution of data and perhaps conducting some descriptive statistics to find out the mean, median, or mode, it is time to make some inferences about the data.

As mentioned previously, inferential statistics are the set of statistical tests researchers use to make inferences about data. These statistical tests allow researchers to make inferences because they can show whether an observed pattern is due to intervention or chance. There is a wide range of statistical tests.
