The wordaverageis of course also very commonly used in more general ways. In math, though, it’s helpful to use more specific terms when determining the most representative or common value in a set of numbers. To illustrate the difference, let’s look at an example set of seven values: ...
Statistics is all about understanding complicated sets of data with fewer and more representative values, like averages. Means and medians are both measures of central tendency, meaning they provide a single value that can give a general picture about a data set. Data sets often need additional ...
If the average is higher than the median, that means the data is right-skewed, meaning the tails of the distribution above the median are longer than below. Average incomes are above median incomes, for example, because it is not possible to make less than 0 in income and some people hav...

The line overxis abar(akaoverbar): a horizontal line written above a mathematical symbol to give it some special meaning. In this case it represents the mean of the setx. Another way of writing it: x̄=1n∑i=1nxix̄=1n∑i=1nxi ...
Some tax credits are "refundable." This means that if the credit reduces your tax bill below $0, the government will send you a check to cover the difference. Other credits are "nonrefundable," meaning that they cannot reduce your tax bill below $0. ...

The digital SAT is section-adaptive, meaning that you will get a harder or easier second module of Math or Reading and Writing depending on how you performed on the first section. If you get the easier second module, your top score will be capped, although there is a lot of overlap in...
In mathematics and statistics, average refers to the sum of a group of values divided byn, wherenis the number of values in the group. An average is also known as amean. Like themedianand themode, the average is a measure of central tendency, meaning it reflects a typical value in a ...
