Central tendency is a descriptive summary of a dataset through a single value that reflects the center of the data distribution. Along with the variability (dispersion) of a dataset, central tendency is a branch of descriptive statistics. The central tendency is one of the most quintessential conc...
Measures of central tendency have been widely used for summarising statistical data, with the mean being the most popular summary statistic. However, in re... K Aristodemou - 《Brunel University》 被引量: 1发表: 2014年 Central Tendency Measures This article defines three different measures of ...

The mode, though the most easily calculated, is the least useful of the measures of central tendency. It cannot be made the basis of any further statistical calculation, and it may give a misleading impression of where the majority of data in a distribution lie....
This paper presents two new estimators of the expectation of a random variable X, which are also unbiased and consistent as an arithmetic mean but more efficient. The first one is called center owing to the fact that its value is usually located between the mean and the median of the ...

However, in the case of infinite variance, there is no such clustering, and regardless of the scale on which measurements are made, there is no change in their central tendency; thus, all scales look the same. Physically, this means that it is difficult or impossible to put limits on the...

Another commonly used measure of central tendency in specific cases is the mode. Themodeis simply the most commonly occurring value. For example, in a class of 50 students graded on a scale of 1-5, the distribution may be as shown in the figure. The mode of this data is 4. ...
The frequency distribution with its graphic representations may adequately represent the status of the data, but it does not enable concise and definite comparison of the features of one distribution with those of another. In order to make such comparisons we need “measures ”of the condensation ...
