**What are the pros and cons of using the mean as a 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).

## 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.[7] Therefore, it is not an appropriate measure of central tendency for skewed distribution.[8] Mean cannot be calculated for nominal or nonnominal ordinal data.

**What are the advantages and disadvantages of mean and median?**

Advantages and disadvantages of averages The mean takes account of all values to calculate the average. Very small or very large values can affect the mean. The median is not affected by very large or very small values. If there is an even number of numbers, the median is found by averaging the two middle numbers.

### What is the purpose of central tendency?

**What is the formula of central tendency?**

Calculate the Central Tendency for this. Solution: Arithmetic Mean is calculated using the formula given below. Arithmetic Mean = ∑x / N. Arithmetic Mean = (5 + 2 + 5 + 6 + 7 + 98 + 1009 + 45 + 34 + 5 + 6 + 56 + 89 + 23) / 14.

**Why mode is the simplest measure of central tendency?**

The mode is the value that occurs the most frequently in your data set. In fact, the mode is the only measure of central tendency that you can use with categorical data—such as the most preferred flavor of ice cream. However, with categorical data, there isn’t a central value because you can’t order the groups.

#### What is the difference between mean and median?

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

#### What does the median tell you?

WHAT CAN THE MEDIAN TELL YOU? The median provides a helpful measure of the centre of a dataset. By comparing the median to the mean, you can get an idea of the distribution of a dataset. When the mean and the median are the same, the dataset is more or less evenly distributed from the lowest to highest values.

**Why use the mean instead of median?**

When you have a normally distributed sample you can legitimately use both the mean or the median as your measure of central tendency. The more skewed the distribution, the greater the difference between the median and mean, and the greater emphasis should be placed on using the median as opposed to the mean.

**How do you compare mean and median?**

The “mean” is the “average” you’re used to, where you add up all the numbers and then divide by the number of numbers. The “median” is the “middle” value in the list of numbers. If no number in the list is repeated, then there is no mode for the list.
