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 measures of central location is affected most by extreme values?
The mean is most affected. Mode and Median are not influenced as much by outliers.
When is the mean used as a measure of central tendency?
When there aren't extreme values (outliers)
What are the characteristics of a good measure of central tendency?
Properties of a good measure of central tendency are:-It should be rigidly defined.It should include all observations.it should be simple to understand and easy to calculate.it should be capable of further mathematical treatment.It should be least affected by extreme observations.it should possess sampling stability.
What is a good measure of central tendency if a data set contains extreme values that may be the result of incorrect measurement?
The median.
Which of three three measures of central tendency is most affected by extreme scores.?
mean
What is the measure of central tendency that is least affected by extreme values?
the variance

What measures of central location is affected most by extreme values?
The mean is most affected. Mode and Median are not influenced as much by outliers.
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.
What effect does the outlier have on the mean?
An outlier can significantly skew the mean of a dataset, pulling it away from the central tendency of the majority of the values. If the outlier is much larger or smaller than the other data points, it can lead to a misleading representation of the average. This sensitivity to extreme values makes the mean less robust compared to other measures of central tendency, such as the median, which is less affected by outliers.
Importance of measures of central tendency?
Measures of the general value are a common need. Average, Median, and Mode are the three commonest.Average is the arithmetic average of all the values.Median is the actual measurement which is midwaybetween the extreme values, and is often closest to the average.Mode is the commonest value.Other indicators of central tendency, may ignore all value beyond say, three standard deviations, and thus ignore the contribution by the extreme, and uncommon, values.
When is the mean used as a measure of central tendency?
When there aren't extreme values (outliers)
Is median affected by extreme values?
No, the median is not affected by extreme values, or outliers, in a data set. The median is the middle value when the data is arranged in order, meaning it remains stable even if the highest or lowest values change significantly. This makes the median a more robust measure of central tendency compared to the mean, which can be skewed by extreme values.

How can the mean affect the outlier?
The mean is sensitive to outliers, as it is calculated by summing all values and dividing by the number of values. A single extreme value can significantly skew the mean, making it higher or lower than the central tendency of the majority of the data points. Consequently, the presence of outliers can misrepresent the overall data distribution and lead to misleading interpretations. In contrast, measures like the median are less affected by outliers, providing a more accurate reflection of the data's central tendency in such cases.
When is mode the better measure?
The mode is the better measure of central tendency when dealing with categorical data, where we want to identify the most common category. It is also useful in skewed distributions or when there are outliers, as it is not affected by extreme values. Additionally, the mode can be the only measure of central tendency applicable for nominal data, where mean and median cannot be computed.
