Which measure of central tendency is robust when outliers are present?
mean
How does the outlier affect the mean median and mode?
An outlier can significantly impact the mean, as it skews the average by pulling it toward its value, potentially misrepresenting the data set's central tendency. The median, however, remains largely unaffected by outliers, as it is determined by the middle value(s) of a sorted data set. The mode, which represents the most frequently occurring value, may also be unchanged if the outlier does not occur frequently. Overall, while the mean can be distorted by outliers, the median provides a more robust measure of central tendency in such cases.
Which measure of central tendency is most influenced by outliers?
The mean is the measure of central tendency most influenced by outliers. Since it is calculated by summing all values and dividing by the number of values, extreme values can significantly skew the result. In contrast, the median and mode are less affected by outliers, making them more robust measures in such situations.
If a data set has many outliers which measure of central tendency would be the BEST to use?
In a data set with many outliers, the median is the best measure of central tendency to use. Unlike the mean, which can be significantly affected by extreme values, the median provides a more accurate representation of the central location of the data. It effectively divides the data into two equal halves, making it robust against outliers. Therefore, the median offers a clearer understanding of the typical value in such cases.

The measure of central tendency that is most affected by a few large or small numbers is?
The mean is the measure of central tendency that is most affected by a few large or small numbers. The median is more robust for extreme values.
What is the appropriate measure of central tendency for age?
The appropriate measure of central tendency for age is the median. This is because age is a continuous variable and can have outliers or extreme values, which can skew the mean. The median provides a more robust estimate of the center of the distribution.
Why is arithmetic mean considered as the best measure of central tendency?
The arithmatic mean is not a best measure for central tendency.. It is because any outliers in the dataset would affect its value thus it is considered not a robust measure.. The mode or median however would be better to measure central tendency since outliers wont affect it value.. Consider this example : Arithmatic mean dan mode from 1, 5, 5, 9 is 5.. If we add 30 to the dataset then the arithmatic mean will be 10 but the mode will still same.. Mode is more robust than arithmatic mean..

What is the difference in using mean and median for confidence intervals?
The mean is sensitive to outliers and skewed data, which can distort the confidence interval, making it wider or narrower than it should be. In contrast, the median is a robust measure of central tendency that is less affected by extreme values, providing a more reliable confidence interval in skewed distributions. Therefore, using the median can yield a more accurate representation of the data's central tendency when the dataset contains outliers. Choosing between mean and median depends on the data's distribution characteristics and the specific analysis requirements.
What is the median temperature?
The median temperature is the middle value of a dataset when the temperatures are arranged in ascending order. If there is an odd number of temperature readings, the median is the middle one; if there is an even number, it is the average of the two middle values. This measure helps to understand the central tendency of temperature data, providing a more robust figure that is less affected by outliers compared to the average.
Is robust a verb or noun?
The word robust is an adjective, a word to describe a noun as strong, healthy, or successful: robust health, a robust economy, a robust business.The noun form for the adjective is robustness.
When was Robust Redhorse created?
Robust Redhorse was created in 1870.
