• Java Program To Calculate Average

I do not have an algortihm but calculating the mean is pretty easy. Just sum up all the numebrs together and then divide them by the total numebr of numbers.

Median is also pretty easy. Turbosquid models. Just sort the collection (there are classes that do it for you) and get the middle number (by dividing the total numbr of elements by 2 and accessing that element).

Mode might be a bit tricky but you can scan the whoel colelction and keep track of all occuring numbers. Havign a hashtable where a numebr is a key and the value is the tiem this number occurs is a good solution. Hope you got an idea. Does this mean I wont be able to get the median using a TreeMap? >>I've already given you the code for doing just that.

How to create a mean, median, and mode calculator? The first example that I provided is a program that calculates mean, median and mode. How to Write a Program in Java to Calculate the Mean. Calculating Mean is very important in day-to-day life. Mean, or mean average, is used along with many other mathematical operations and is an important thing to know. How to calculate Standard Deviation through a Java program. Mean; Median; Mode.

Java Program To Calculate Average

>> > I can't see how your code calculates the median. And to elaborate more, you can't just get the median if you divide the size of the hash by 2 since duplicate doubles will be acumulated under the same key. Think about how the median changes here: 10 10 10 10 20 30 where the median is 10 while in a hash's case it would be: 10 20 30 where median is 20 since hash's size will be the number of the keys not the number of the values.
