Psychology Glossary. Correlation Coefficient. This is a measure of the direction (positive or negative) and extent (range of a correlation coefficient is from -1 to +1) of the relationship between two sets of scores. Scores with a positive correlation coefficient go up and down together (as with smoking and cancer).
Den (room) A den is a small room in a house where people can pursue activities in private. In the United States, the type of rooms described by the term den varies considerably by region. It is used to describe many different kinds of bonus rooms, including studies, family rooms, home offices, libraries, home cinemas, or even spare bedrooms. In some places, particularly in parts of the British Isles, a small den may be known as a snug.
A lair is a wild animal's den. If you ever find yourself in a forest and face to face with a bear trying to lure you into his lair, beware! He may be plotting to eat you. The noun lair has its roots in the Old English leger, meaning âbed, couch, place of lying down.â It eventually became an âanimalâs denâ in the early 15th century. A person can have a lair, too, like the photo-covered basement of a serial killer, or a less scary person might have a cozy lair lined with plush carpet. Always poke a stick into a lair before going in, because you never know what sort of beast is lurking inside.
