Measure of Central Tendency

The arithmetic mean is usually skewed towards the larger values in the data set. Therefore, to avoid this inherent bias towards smaller values, the …

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 …

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 …

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 …

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 …

Descriptive statistics describe or summarize relevant characteristics of a sample and aid in the analysis of data of interest. When analyzing large …

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 …

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 …

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, …

Sometimes, data gathered from an experiment on a large sample or population are organized into concise tables. In such cases, the frequency of the …

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 …

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 …

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 …
