# What are two measures of central tendency?

## What are two measures of central tendency?

There are three main measures of central tendency: the mode, the median and the mean. Each of these measures describes a different indication of the typical or central value in the distribution.

**What are the two measures of dispersion?**

Range, interquartile range, and standard deviation are the three commonly used measures of dispersion.

**What are the two measures of dispersion variability?**

Measures of Dispersion or Variability Measures of dispersion describe the spread of the data. They include the range, interquartile range, standard deviation and variance.

### What is central dispersion?

Measures that indicate the approximate center of a distribution are called measures of central tendency. Measures that describe the spread of the data are measures of dispersion. These measures include the mean, median, mode, range, upper and lower quartiles, variance, and standard deviation.

**What is the difference between central tendency and dispersion?**

Central tendency gets at the typical score on the variable, while dispersion gets at how much variety there is in the scores. When describing the scores on a single variable, it is customary to report on both the central tendency and the dispersion.

**What is dispersion and measures of dispersion?**

Dispersion is the state of getting dispersed or spread. Statistical dispersion means the extent to which numerical data is likely to vary about an average value. In other words, dispersion helps to understand the distribution of the data.

#### What is the best measure of central tendency and dispersion?

The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data is normally distributed.

**What is tendency and dispersion?**

Central tendency is described by median, mode, and the means (there are different means- geometric and arithmetic). Dispersion is the degree to which data is distributed around this central tendency, and is represented by range, deviation, variance, standard deviation and standard error.

**What is measure of dispersion?**

A measure of dispersion indicates the scattering of data. It explains the disparity of data from one another, delivering a precise view of their distribution. The measure of dispersion displays and gives us an idea about the variation and the central value of an individual item.

## What are the common examples of measures of statistical dispersion?

Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range.

**Which is a measure of dispersion?**

Standard deviation, Range, Mean absolute difference, Median absolute deviation, Interquartile change, and Average deviation are examples of measures of dispersion.

**What is the difference between measures of central tendency and dispersion?**

Measures of central tendency are mean, mode and median , whereas measures of dispersion are variance, standard deviation and interquartile range (it explains the extent to which distribution stretched or squeezed).

### What is dispersion and central tendency?

**Why we have to study dispersion together with measures of central tendency?**

While measures of central tendency are used to estimate “normal” values of a dataset, measures of dispersion are important for describing the spread of the data, or its variation around a central value. Two distinct samples may have the same mean or median, but completely different levels of variability, or vice versa.

**What are the best measures of central tendency?**

Mean is the preferred measure of central tendency when data is normally distributed.

#### How do you calculate the measure of central tendency?

Measures of Central Tendency. The central tendency of the dataset can be found out using the three important measures namely mean, median and mode. Mean. The mean represents the average value of the dataset. It can be calculated as the sum of all the values in the dataset divided by the number of values.

**What are the common measures of central tendency?**

Central Tendency : Center of the data set. In one of the previous posts on probability distribution and Histograms,we spoke about the frequency distribution of a data set.

**What is the best measure of central tendency and why?**

If you have a symmetrical distribution of continuous data,all the three measures of central tendency hold good.
