What do you do if there is two medians in a set of data?
Go halfway between the two. If your two medians are, say, 27 and 29, the median is 28 :)
What can you do when there are two medians in a set of numbers?
Then all you do is add those two medians and then divide them by 2.
What is cumolative frequency curve?
A cumulative frequency curve is a graph that shows the cumulative frequency of a data set. This type of graph can present data, such as medians and quartiles. Another name for this curve is an Ogive.
What should you do if you have two medians?
If there is an even number of data points in a set, there will two numbers which "share" the position of being the median; in this case the numbers are added together and the result divided by 2, to give the median for that set.
If you have more than one median what do you do?
If you have an even set of data then there are two middle numbers or medians. Average those two and create a median. Example: 2,3,4,7,9,10 4 and 7 are in the middle. (4+7)/2=5.5 5.5 is the median even though it is not one of the numbers in the data set.
