What is wrong about good measure of central tendency?

Measures of central tendency does not give the overall picture and they can be misleading. Central tendency are greatly influenced by other factors. Such as mean by outliers. For this reason it’s better to use measures of dispersion with central tendency.

What is the main disadvantage of using mean as a measure of central tendency?

The mean is the only measure of central tendency where the sum of the deviations of each value from the mean is always zero. On the other hand, the one main disadvantage of the mean is its susceptibility to the influence of outliers.

What are the advantages and disadvantages of measures of central tendency?

Advantages and disadvantages of measures of central tendency

• Good to use with ordinal data.
• It is generally unaffected by anomalies and so safer to use with extreme values.

How measures of central tendency are used in research?

The measures of central tendency allow researchers to determine the typical numerical point in a set of data. The data points of any sample are distributed on a range from lowest value to the highest value. Measures of central tendency tell researchers where the center value lies in the distribution of data.

Why are the measures of central tendency necessary to describe a set of data?

Measures of Central Tendency provide a summary measure that attempts to describe a whole set of data with a single value that represents the middle or centre of its distribution. It’s important to look the dispersion of a data set when interpreting the measures of central tendency.

Which is not the best measure of central tendency?

Summary of when to use the mean, median and mode

Type of Variable	Best measure of central tendency
Nominal	Mode
Ordinal	Median
Interval/Ratio (not skewed)	Mean
Interval/Ratio (skewed)	Median

What are the pros and cons of using the mean as a measure of central tendency for this test?

Mean is the most popular measure of central tendency. Pro: Generally the best measure of central tendency because, it utilizes all the scores. Con: Very sensitive to outliers (extreme scores).

Why not use only median as a measure of central tendency?

The median is usually preferred to other measures of central tendency when your data set is skewed (i.e., forms a skewed distribution) or you are dealing with ordinal data. However, the mode can also be appropriate in these situations, but is not as commonly used as the median.

What are the drawbacks of central tendency methods?

It is a positional average and does not consider the magnitude of the items. It neglects the extreme values. It is not dependent on all the observations, so it cannot be considered as their good representative. In case there is a big variation between the data, it will not be able to represent the data.

What is the disadvantage of using the sum of squared deviations for measuring variability?

Standard deviation (SD) is the most commonly used measure of dispersion. It is a measure of spread of data about the mean. SD is the square root of sum of squared deviation from the mean divided by the number of observations. The disadvantage of SD is that it is an inappropriate measure of dispersion for skewed data.

Why are measures of central tendency important to descriptive statistics?

These three central tendency measures indicate the central point around which all the data gather. That is why it is one of the two essential parts of descriptive statistics. So with central tendency, we know the center of the distribution of data. With dispersion, we know how spread the data are.

Which measure of central tendency is considered most reliable?

Mean is generally considered the best measure of central tendency and the most frequently used one.
