oulier means something that sticks out in math, like in the number 50, 51, 53, 54, & 100... 100 is the outlier
What else can I help you with?
Disadvantages of the mean in statistics?
the mean is affected by outliers
What is most sensitive to outliers in statistics?
Mean.
Why is the mean the best to use for outliers?
just cuz
Is absolute mean deviation affected by outliers?
Yes.
What is the effect of extreme value on mean?
Outliers pull the mean in the direction of the outlier.
How does the outlier affect the mean and median?
The mean is better than the median when there are outliers.
What are the limits on outliers?
there are no limits to outliers there are no limits to outliers
Which measure of central tendency is robust when outliers are present?
mean
How can you determine which measure of central tendency is best for the set if data?
Mean- If there are no outliers. A really low number or really high number will mess up the mean. Median- If there are outliers. The outliers will not mess up the median. Mode- If the most of one number is centrally located in the data. :)
What are the measurements that fall beyond three standard deviations from the mean?
They are observations with a low likelihood of occurrence. They may be called outliers but there is no agreed definition for outliers.
When is the median more useful than the mean?
When the distribution has outliers. They will skew the mean but will not affect the median.
How can the median and mean be different?
You will notice a difference in the data if you have outliers. The mean of a set is going to be heavily influenced by outliers due to the mean being dependant on the quantity of each unit (i.e. 2 cats, 7 cats, 300 cats, etc.) The median, however, is not influenced by outliers because it accounts for the number of units rather than the quantity associated with the units.
