Welcome to MooMooMath where we upload a new Math video everyday. In this video I would like to talk about what an outliers and how the affect measure of center.
An OUTLIER is when one data value is much greater
or much less than the rest of the data values in the
set.
An OUTLIER may affect a measure of center.
Determine how the outlier affects the median and the mean in the
following quiz scores.
55, 88, 90, 93, 94
Indentify the outlier yes it is 55
Next Find the median
Determine how the outlier affects the median by finding the median WITHOUT the outlier included.
MEDIAN = WITHOUT THE OUTLIER
Is as follows.
Did the median change? By how much? 1.5
Next, Calculate the mean
Determine how the outlier affects the mean by finding the mean
WITHOUT the outlier included.
MEAN = WITHOUT THE OUTLIER
Did the mean change? yes By how much? 7.25
Which measure of center changed MORE with the outlier?
The mean
WHEN THERE IS AN OUTLIER, IT IS BEST TO USE THE
MEDIAN
No outlier use mean when finding the measure of center
of comparing the measure of center
