Introduction to median and outliers calculator:
This article will help you to calculate median and outliers .A median of a data set is the middle item (if the number of items is odd) or the mean of the middle two terms (if the number of items is even), when the items are arranged in an order.
An outlier in a data set is that item which can be termed as the odd-man out.
Let us study in detail and try to build a sort of median and outliers calculator.
Median and Outliers Calculator – Outlier
As explained earlier, an outlier is a visibly abnormal item in a set of items in a data. Suppose a data is made of the ages of teachers in your school and expressed as,
(36, 38, 41, 40. 62, 37, 39).
You see that the age of one teacher is 62, way out from the age group of the remaining teachers. Hence the this item (that is, age 62) is an outlier in the set.
Let us try to find the median of the above data in two different ways. First by taking all the items as it is and second by ignoring the outlier.
You will find the median in the first case as 39 and in the second case as 38.5. This leads to the conclusion that an outlier does not greatly change the median of a data set. So in such circumstances, the median is better measure than the mean in a data set. Please express your views of this topic how to find the volume of a cone by commenting on blog
Median and Outliers Calculator – Median
Having said that the median of a data is more reliable than the mean, it is also important that you limit this conclusion only when you find some outliers in the data. Otherwise, still the mean of a data is stronger than the median. The following example will clarify this point.
A student’s score on a scale of 100 are as shown below, arranged in an ascending order.
10, 15, 30, 35, 95, 95, 100
The scores are erratic when you look at is without knowing further details of the data. It is quite possible, the student had some short comings in the beginning but successfully got over that and changed brilliantly.
The median (which is 35) does not reveal about the student’s improvement where as the mean ( which is about 54) indicates that.
