 ## What is mean and its merits and demerits?

1) Arithmetic mean rigidly defined by Algebraic Formula.

2) It is easy to calculate and simple to understand.

3) It is based on all observations of the given data.

4) It is capable of being treated mathematically hence it is widely used in statistical analysis..

## What are the disadvantages of models?

Disadvantages of modelling and simulation The cost of a simulation model can be high. The cost of running several different simulations may be high. Time may be needed to make sense of the results. People’s reactions to the model or simulation might not be realistic or reliable.

## Why mean is important?

The mean is an important measure because it incorporates the score from every subject in the research study. The required steps for its calculation are: count the total number of cases—referred in statistics as n; add up all the scores and divide by the total number of cases.

## What is a disadvantage of using the median?

Disadvantages. It does not take into account the precise value of each observation and hence does not use all information available in the data. Unlike mean, median is not amenable to further mathematical calculation and hence is not used in many statistical tests.

## What are the pros and cons of using the mean as your measure of central tendency?

The mean is the arithmetic average of the scores of a distribution. 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).

Advantage means that it provides a beneficial function to something. A disadvantage means that it prevents beneficial functions.

## What is the advantage of using mean?

Arithmetic mean is simple to understand and easy to calculate. It is rigidly defined. It is suitable for further algebraic treatment. It is least affected fluctuation of sampling.

## What are examples of disadvantages?

The definition of a disadvantage is an unfavorable situation or something that puts someone in an unfavorable situation. An example of a disadvantage is a baseball player not being able to play. An example of a disadvantage is a baseball team’s star player having to sit out because of an injury.

## What is a disadvantage of using the mean?

The important disadvantage of mean is that it is sensitive to extreme values/outliers, especially when the sample size is small. Therefore, it is not an appropriate measure of central tendency for skewed distribution. Mean cannot be calculated for nominal or nonnominal ordinal data.
