Related to Central Tendency: standard deviation, measures of dispersion


number used to represent or characterize a group of numbers. The most common type of average is the arithmetic meanmean,
in statistics, a type of average. The arithmetic mean of a group of numbers is found by dividing their sum by the number of members in the group; e.g., the sum of the seven numbers 4, 5, 6, 9, 13, 14, and 19 is 70 so their mean is 70 divided by 7, or 10.

1 In statistics, a type of average. In a group of numbers as many numbers of the group are larger than the median as are smaller. In the group 4, 5, 6, 9, 13, 14, 19, the median is 9, three numbers being larger and three smaller.

; modemode,
in statistics, an infrequently used type of average. In a group of numbers the mode is the number occurring most frequently. In the group 1, 4, 5, 5, 6, 6, 6, 6, 9, 9, the mode is 6 because it occurs four times and the others only once or twice.

in maritime law. (1) General average—property damage caused intentionally to a ship or its cargo to avoid danger to both or to forestall losses (for instance, the jettison of cargo or of ship provisions to lighten the ship in trying to get off a sandbank). The USSR Trade Navigation Code defines general average as losses suffered as a consequence of intentional and reasonable emergency expenditures and sacrifices to save a ship or its cargo from danger. The losses incurred in the case of general average are distributed proportionally according to the value of the ship, freight, and heavy loads.

(2) Particular average—unintentional damage caused to a ship or its cargo or in connection with their movement; the losses in the case of particular average are borne by those who suffered them or by those who are responsible for having caused them.

In Soviet legislation questions relating to general and particular average are regulated by the USSR Trade Navigation Code. In international trade, relations arising out of general average are regulated by the York-Antwerp Rules (the 1950 edition). These rules are applied only according to an agreement between the parties included in their contract of affreightment.




1. the result obtained by adding the numbers or quantities in a set and dividing the total by the number of members in the set
2. (of a continuously variable ratio, such as speed) the quotient of the differences between the initial and final values of the two quantities that make up the ratio
3. Maritime law
a. a loss incurred or damage suffered by a ship or its cargo at sea
b. the equitable apportionment of such loss among the interested parties

The first two measures of central tendency, the mean and the median, work well with data that represent some quantity, such as time expended and work units produced.
Calculate the quarterly means (or calculate the measures of central tendency for the time periods you have chosen).
Therefore, many researchers report the median RT as a central tendency parameter, because it is less susceptible to departures from normality (i.
The primary goal of this article is to evaluate the reliability of the midpoint of the central tendency as a measure of consensus.
I think that measures of central tendency need to be personalized to accomplish student buy-in.
Three common measures of central tendency are arithmetic mean, mode and median.
For example, measures of central tendency are one of the most important topics: students should be enabled to find the way of determining median value intuitionally, as well as to estimate the reason why it is so different from mean and mode, for example.
For example, statistical fundamentals (such as the normal distribution and probability) are presented within the context of sampling theory early on in the text, which lays the groundwork for the later chapter on quantitative data analysis, which discusses issues of central tendency, dispersion, and statistical inference.
Within any particular operational mode, climate is robust, possessing natural variability around a dynamic central tendency, alongside the capacity to absorb significant impacts without changing its fundamental operation.
Having laid out the statistical roadmap, the next few chapters cover the essential statistical tools: dataframes, central tendency, variance (this topic, Crawley suggests, is the most important one in the book because of its central importance in statistical analysis), the statistics of single and double samples.
The aim of the paper is to show that using a fraction of a central tendency as the poverty line restricts the evolution of poverty statistics to be stable when the inequality is stable.
htm) were administered as part of a larger online survey that also examined conceptual and procedural understandings of central tendency and standard deviation (questions 2, 4, and 6), and attitudes toward statistics (a separate survey).
