How do you determine how the outlier affects the mean median mode and range?

Calculate the mean, median, and range with the outlier, and then again without the outlier. Then find the difference. Mode will be unaffected by an outlier.

Which is affected more by the outlier the ranger or the interquartile range?
The Interquartile Range because it affects how much space is left between the median on either side....So there you go! I hope that I helped You... : D
What is an outlier when finding the median?
an outlier can be found with this formula... Q3-Q1= IQR( inner quartile range) IQR*1.5=x x+Q3= anything higher than this # is an outlier Q1-x= anything smaller than this # is an outlier
What is an example of a outlier range?
1,2,3,4,20 20 is the outlier range
What is an outlier in stats?
An outlier, in a set of data, is an observation whose value is distant from other observations. There is no exact definition but one commonly used definition is any value that lies outside of Median ± 3*IQR IQR = Inter-Quartile Range.
What is the calculation that you use to find an outlier?
There is no agreed definition of an outlier. There are some definitions based on the median (Q2) and the quartiles Q1, and Q3.Let the inter-quartile range, IQR = Q3 - Q1.A number is a n outlier if it is:less than Q1 - k*IQR orgreater than Q3 + k*IQR.A popular choice for k is 1.5
How does the outlier affect the mean median mode and range?
The outlier is capable of affecting mean median mode and range it affects mean because the average has changed if affects median because you have to cross out 1 more letter it doesn't affect mode it does affect range because an outlier is a number that i far away from the other numbers * * * * * It does not affect the median.

How does the outlier change the mean median mode and range with these numbers 5 13 13 15 18 20 20 20?
Mean: 15.5 Median: 16.5 Mode: 20 Range: 15
What is an example of a outlier range?
1,2,3,4,20 20 is the outlier range
How does an outlier effect the range?
An outlier will have a huge affect on the range as the range is the largest value minus the smallest value.

Does an outlier have a greater effect on the standard deviation or interquartile range?
On the standard deviation. It has no effect on the IQR.
Explain the difference between the range and the outlier?
Range is the largest minus the smallest value in the data set. An outlier is a value that is far away from the majority of the data.
If you take off the outlier does it make the mean change?
Yes, it will. An outlier is a data point that lies outside the normal range of data. This means that if it is factored in the mean will move in the direction the outlier is, really high if the outlier was high, and really low if the outlier was low.
How does the outlier affect the median of this data?
An outlier is 1.5 times the mean, when you are taking an average it may give an inaccurate representation of the data. It usually does not affect the median.* * * * * The above definition of an outlier is total rubbish! It is necessary to have a measure of the central tendency (mean or median) AND spread (standard deviation or inter quartile range - IQR) to define an outlier.If Q1 and Q3 are the lower and upper quartiles, then outliers are normally defined as observations lying below Q1 - k*IQR or above Q3 + k*IQR. There is no universally agreed definition of outliers and hence no fixed value for k. But k = 1.5 is often used.
