Measure of Central Tendency

Harmonic Mean
The arithmetic mean is usually skewed towards the larger values in the data set. Therefore, to avoid this inherent bias towards smaller values, the …
Weighted Mean
While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the …
Root Mean Square
If in an experiment, data values have a probability of being both positive and negative, neither the arithmetic mean, the geometric mean, nor the harmonic …
Midrange
A somewhat easy to compute quantitative estimate of a data set’s central tendency is its midrange, which is defined as the mean of the minimum and …
Types of Skewness
If the frequency distribution of a data set is more inclined towards smaller or larger values, the distribution is said to be skewed. If data values are …
What is Central Tendency?
Descriptive statistics describe or summarize relevant characteristics of a sample and aid in the analysis of data of interest. When analyzing large …
Arithmetic Mean
The arithmetic mean is the most commonly used measure of the central tendency of a data set. It is defined as the sum of all the elements constituting the …
Geometric Mean
The mean is a measure of the central tendency of a data set. In some data sets, the data is inherently multiplicative, and the arithmetic mean is not …
Trimmed Mean
While measuring the mean of a data set, care needs to be taken when associating the mean to its central tendency. The same goes for the arithmetic mean, …
Mean From a Frequency Distribution
Sometimes, data gathered from an experiment on a large sample or population are organized into concise tables. In such cases, the frequency of the …
What is a Mode?
The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set. There can be more than one …
Median
Besides mean, the median is a widely used measure of central tendency. Typically, median is defined as the central or middle value of a data set, measured …
Skewness
The measures of central tendency calculated from a data set may not reveal much about its intrinsic distribution. If a plot is made of the data …
A Microfluidic Technique to Probe Cell Deformability
Here we detail the design, fabrication, and use of a microfluidic device to evaluate the deformability of a large number of individual cells in an …
Applying an eMASS Customization Program as a Research Tool to Evaluate Consumer Benefits
As many scholars and practitioners study personalization and relationship marketing, it is important to provide personalization such as mass customization …
Rapid Repetition Rate Fluctuation Measurement of Soliton Crystals in a Microresonator
Temporal solitons have attracted great interest in the past decades for their behavior in a steady state, where the dispersion is balanced by the …
