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.
What are the limits on outliers?
there are no limits to outliers there are no limits to outliers
Which of the following is least affected if an extreme high outlier is added to your data mean median or standard deviation or ALL?
The median is least affected by an extreme outlier. Mean and standard deviation ARE affected by extreme outliers.
What do box and whisker plots tell you about data that measures of central tenancy do not?
The box and whisker plot informs you of the 5 number summary, which comprises of the minimum and maximum, the median, and the first and third quartiles. The minumum and maximum give you the range, which is not given by measures of central tendancy. also, if it a modified box and whisker plot, outliers will be marked separatley from the rest of the plot, outliers are also not included in the measures of center.
Is range is not considered to be an index of despersion?
The sample range could be used as an index of dispersion. However, there are objections. One is that this statistic is obviously sensitive to outliers. Another is that for many population distributions there are measures with much better characteristics, even ignoring the problem of outliers.
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.
Disadvantages of the mean in statistics?
the mean is affected by outliers
Is absolute mean deviation affected by outliers?
Yes.
What is affected by extreme outliers?
Extreme outliers can greatly distort statistical measures such as the mean and standard deviation, making them less representative of the data. They can also impact the accuracy of predictive models by leading to overfitting. In some cases, outliers may signal data quality issues or the presence of unexpected patterns in the data that warrant further investigation.
How do outliers affect measures of center?
Outliers can significantly skew measures of center, such as the mean, by pulling the average in their direction, which may not represent the overall data well. For instance, a single extremely high or low value can distort the mean, making it less reflective of the typical values in the dataset. In contrast, the median is more robust against outliers, as it focuses on the middle value, thus providing a more accurate measure of central tendency in such cases. Overall, the presence of outliers necessitates careful consideration when interpreting measures of center.
What are the limits on outliers?
there are no limits to outliers there are no limits to outliers
Is the mean a better measure of location when there are no outliers?
Yes, the mean is generally a better measure of central tendency when there are no outliers, as it takes into account all values in the dataset and provides a mathematically precise average. In the absence of outliers, the mean reflects the true center of the data distribution effectively. However, in the presence of outliers, the median might be preferred since it is less affected by extreme values.
Which of the following is least affected if an extreme high outlier is added to your data mean median or standard deviation or ALL?
The median is least affected by an extreme outlier. Mean and standard deviation ARE affected by extreme outliers.

What are the rehabilitation measures for the flood affected?
