 # Question: Which Measure Of Central Tendency Is Most Influenced By Outliers Quizlet?

## Which measure of central tendency is the most appropriate and why?

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..

## Which of the following is the most influenced by outliers quizlet?

Which of the measures of central tendency is most influenced by outliers in your data? The mean is strongly influenced by outliers because it is the average of the scores and it is not resistant. The median is resistant.

## Can a data set have the same mean median and mode?

Some quantitative data sets do not have medians. A data set can have the same mean, median, and mode. When each data class has the same frequency, the distribution is symmetric. … For a symmetric distribution, the standard deviation and mean are equal.

## Which of the following is a measure of central tendency that is resistant to outliers?

The median is more resistant to outliers. The median and mean have slightly different interpretations. Both tell about where the “typical” or “central” value in a distribution is found. For a symmetric distribution such as the normal distribution, the mean and the median are the same number.

## Which is a better measure of central tendency mean or median?

Mean is the most frequently used measure of central tendency and generally considered the best measure of it. … Median is the preferred measure of central tendency when: There are a few extreme scores in the distribution of the data.

## Which of the following are measures of central tendency quizlet?

The most common measures of central tendency are mean, median, and mode. The RANGE is also used to describe a set of data.

## What is most influenced by outliers?

Only the arithmetic mean which is the sum of the observations over the number of observations is likely to be affected in a large way. An outlier can drastically affect the mean as it will hold a larger weight to other observations since it is so far away from the median.

## What is affected by outliers in statistics?

An outlier is an unusually large or small observation. Outliers can have a disproportionate effect on statistical results, such as the mean, which can result in misleading interpretations. … In this case, the mean value makes it seem that the data values are higher than they really are.

## Which measure of central tendency is most influenced by outliers?

MeanMean is the only measure of central tendency that is always affected by an outlier. Mean, the average, is the most popular measure of central tendency.

## Which measure of central tendency is most affected by a skewed distribution?

medianFor normally distributed data, all three measures of central tendency will give you the same answer so they can all be used. In skewed distributions, the median is the best measure because it is unaffected by extreme outliers or non-symmetric distributions of scores. The mean and mode can vary in skewed distributions.

## Which of the following is not a measure of central tendency group of answer choices?

Standard deviation is not a measure of Central tendency.

## Which of the following are the three most common measures of central tendency?

You can think of it as the tendency of data to cluster around a middle value. In statistics, the three most common measures of central tendency are the mean, median, and mode. Each of these measures calculates the location of the central point using a different method.

## Which relation among three measure of central tendency mean median and mode is correct?

Thus, the empirical relationship between the three measures of central tendency is 2 Mean = 3 Median – Mode. Hence, option (a) is the correct answer.

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

Advantages and disadvantages of measures of central tendencyThe figure produced will be one that is actually in the set of numbers which is not always true for other measures of central tendency e.g. in a sequence of 3 6 3 11 4 3, the mode = 3. This number we can see is present in the sequence. … It is the only measure of central tendency which is useful for nominal data.

## Which of the following measures of central tendency is least influenced by outliers?

What is the most appropriate measure of central tendency when the data has outliers? The median is usually preferred in these situations because the value of the mean can be distorted by the outliers. However, it will depend on how influential the outliers are.
