How would the outlier affect the mean and median of the data?
An outlier will pull the mean and median towards itself. The extent to which the mean is affected will depend on the number of observations as well as the magnitude of the outlier. The median will change by a half-step.
Which measure of central tendency best describes the data set wit an outlier?
The median.
How The first quartile of a data set is 23 the median is 30 the third quartile is 33 and an outlier is 50. Which of these data values would be represented by a point in a modified box plot?
It is the outlier.
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.
The first quartile of a data set is 23 the median is 30 the third quartile is 33 and an outlier is 50. Which of these data values would be represented by a point in a modified box plot?
50
Given the following data 164 175 126 135 159 143 55 what effect will the outlier have on the median of the data if the outlier is excluded?
If the outlier is excluded the median of the data will be higher.
How does an outlier affect data?
it messes up the mean and sometimes the median. * * * * * An outlier cannot mess up the median.

Which lists the correct median for the data without the outlier?

It is the outlier.
How does the outlier effect the mean median and mode in a set of data?
There would be a difference to the median. The old number wouldn't be the median but the mode wouldn't change. If the outlier is a high value, it will cause the mean value to shift to the higher side, while a low valued outlier will drop the mean value to a lower number.
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 will happen if the outlier is taken out of a data set?
The mean is changed.
What will happen to the mean if the outlier 80 is taken out of the data set 30 35 80 35 30?
It will go down; with outlier, mean is 42 without outlier, mean is 32.5
What happens to the mean median and mode for the data shown if the outlier is eliminated 8 3 5 3 23 4 7?
The mean and median become smaller, the mode does not change.
What is an outlier in math and can you get rid of it?
An outlier, in a distribution of data points, is a value which does not fall within three standard deviations of the mean. You cannot, at least directly, remove an outlier without biasing the data itself, but you can choose different measures to try and soften their effects. For example, instead of using mean as a measurement for the central value of the data set, one can use median.
