Statistics is a discipline that deals with data, facts, and figures from which meaningful information is inferred. It involves gathering, summarizing, and analyzing data to understand trends and patterns. Statistics can be divided into two main types: descriptive statistics, which summarize data, and inferential statistics, which make predictions or inferences about a population based on a sample
But, reading statistical income information can be full of pitfalls. One needs to look at the mean and median. Both give useful information. By comparing the two, one can ascertain if there are outliers that affect the results.
Example:
If a sample of 10 physicians has one earning $1,000,000 and the other nine earning $100,000, the average (mean) income is $190,000; but the median income is $100,000.
Just using this information alone, one can tell there are some outliers that could affect the results.

Example:
“Lies, damned lies, and statistics” is a phrase describing the persuasive power of statistics to bolster weak arguments, “one of the best, and best-known” critiques of applied statistics. It is also sometimes colloquially used to doubt statistics used to prove an opponent’s point.
-Benjamin Disraeli [1st Earl of Beaconsfield]
