The mean is most often used as the central tendency. Other methods of arriving at the central tendency include finding the median and the mode. If scores are organized from the lowest to the highest, or the highest to the lowest, the median score is the middle score. Half of the grades are below this score and half are above. The mode is the most frequent score.
Places are parts of Earth's surface endowed with meaning by humans.
Each place possesses a distinctive set of tangible and intangible characteristics that help to distinguish it from other places. Its physical characteristics include climate, landforms, soils, hydrology, vegetation, and animal life. Its human characteristics include language, religion, political systems, economic systems, population distribution, and quality of life. The identity of people is influenced by the character of the place they come from. Personal identity, community identity, and national identity are rooted in place and attachment to place.
