Have you built a site on a Squarespace template such as Flatiron or Marquee supporting the concept of index pages or index collections?

CSS style rules let you bust into full-on, creative mode when designing websites on the Squarespace platform. The Squarespace promise is one of gorgeous template designs that you build out with drag-and-drop ease. Yet no matter how good the template, there is always just that one little tweak that you want to make, that wasn't accounted for by the template's designer. Knowing how to create and apply CSS rules helps you avoid the cookie-cutter look by customizing your site's design beyond the limited set of choices provided by the template.

Median is a measure of central tendency useful in describing the typical experience, or the typical case.

Oracle Database implements a family of STDDEV functions for computing the standard deviation from the mean. If you think of the mean as beginning to paint a picture of the underlying data, then standard deviation is another brush-stroke toward a fuller picture that will help you draw meaning from the data you're studying.
AVG is an aggregate function in SQL to compute the "average" of a set of values. More precisely, it computes the mean of those values. And even more precisely, AVG computes what is known as the arithmetic mean. But keep reading! Learning about "average" is like uncovering an iceberg. There's more to it than meets the eye.
The framing clause brings the "window" to window functions. It's an ideal solution when you can arrange a business question such that an answer comes from applying an aggregate function to a range of rows that slides or stretches smoothly as focus moves from one row to the next. Running sums and moving averages are just two examples of such problems.
Look to ROW_NUMBER, RANK, and DENSE_RANK anytime you are faced with a business question involving words or phrases such as "topmost" or "bottommost", "top N" or "bottom N", or that is otherwise answerable by ranking the rows in a result set according to some criteria that you can apply to one or more columns of data.
