median



                                  median


Hi,
  Today we are going to talk about median.The definition of median is the middle value when the values are written in numerical order.If a data set has an even number of values,the median is the mean of the two middle values.we will be doing some practice next paragraph.That is what median is.


lets do the problem 23,24,25,27,28,19,30.first we put the numbers in order.19,23,24,25,27,28,30.Then we find the middle.25.That is how you find median.thank you.
