## What is the difference between measures of central tendency and measures of dispersion for summarizing data with suitable example?

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 measure of central tendency and measure of location?

Central tendency (sometimes called “measures of location,” “central location,” or just “center”) is a way to describe what’s typical for a set of data. Central tendency doesn’t tell you specifics about the individual pieces of data, but it does give you an overall picture of what is going on in the entire data set.

What is the difference between measures of dispersion and measures of variability?

While a measure of central tendency describes the typical value, measures of variability define how far away the data points tend to fall from the center. A low dispersion indicates that the data points tend to be clustered tightly around the center. High dispersion signifies that they tend to fall further away.

### 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 are the different measures of central tendency with example?

Another measure of central tendency is the median, which is defined as the middle value when the numbers are arranged in increasing or decreasing order. For example, if we had four values—4, 10, 12, and 26—the median would be the average of the two middle values, 10 and 12; in this case, 11 is the median.

What is the best measure of central tendency?

The mean
The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. For data from skewed distributions, the median is better than the mean because it isn’t influenced by extremely large values.

## What you mean by central tendency?

Central tendency is defined as “the statistical measure that identifies a single value as representative of an entire distribution.” It aims to provide an accurate description of the entire data. The mean, median and mode are the three commonly used measures of central tendency.

## What are the five measures of dispersion?

Examples of dispersion measures include:

• Standard deviation.
• Interquartile range (IQR)
• Range.
• Mean absolute difference (also known as Gini mean absolute difference)
• Average absolute deviation (or simply called average deviation)
• Distance standard deviation.

What is the best measure of dispersion?

Standard deviation
Standard deviation (SD) is the most commonly used measure of dispersion. It is a measure of spread of data about the mean.

### What are the three measures of central tendency?

Measures of central tendency are numbers that describe what is average or typical within a distribution of data. There are three main measures of central tendency: mean, median, and mode.

### What is an example of a measure of central tendency?

Measures of Central Tendency. Measures of central tendency are numbers that tend to cluster around the “middle” of a set of values. Three such middle numbers are the mean, the median, and the mode. For example, suppose your earnings for the past week were the values shown in Table 1.

What are measures of dispersion?

In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range.

## What is an example of central tendency?

Central tendency bias (sometimes called central tendency error) is a tendency for a rater to place most items in the middle of a rating scale. For example, on a 10 point scale, a manager might place most of his employees in the middle (4-7), with a few people getting high(8-10) or low(1-3) rated performances.
