When analyzing numerical data, you may often be looking for some way to get the 'typical' value. For this purpose, you can use the so-called measures of central tendency that represent a single value identifying the central position within a data set or, more technically, the middle or center in a statistical distribution. Sometimes, they are also classified as summary statistics.
The three main measures of central tendency are Mean, Median and Mode. They all are valid measures of central location, but each gives a different indication of a typical value, and under different circumstances some measures are more appropriate to use than others.
How to calculate mean in Excel
Arithmetic mean, also referred to as average, is probably the measure you are most familiar with. The mean is calculated by adding up a group of numbers and then dividing the sum by the count of those numbers.
For example, to calculate the mean of numbers {1, 2, 2, 3, 4, 6}, you add them up, and then divide the sum by 6, which yields 3: (1+2+2+3+4+6)/6=3.
In Microsoft Excel, the mean can be calculated by using one of the following functions:
- AVERAGE- returns an average of numbers.
- AVERAGEA - returns an average of cells with any data (numbers, Boolean and text values).
- AVERAGEIF - finds an average of numbers based on a single criterion.
- AVERAGEIFS - finds an average of numbers based on multiple criteria.
For the in-depth tutorials, please follow the above links. To get a conceptual idea of how these functions work, consider the following example.
In a sales report (please see the screenshot below), supposing you want to get the average of values in cells C2:C8. For this, use this simple formula:
=AVERAGE(C2:C8)
To get the average of only 'Banana' sales, use an AVERAGEIF formula:
=AVERAGEIF(A2:A8, 'Banana', C2:C8)
To calculate the mean based on 2 conditions, say, the average of 'Banana' sales with the status 'Delivered', use AVERAGEIFS:

=AVERAGEIFS(C2:C8,A2:A8, 'Banana', B2:B8, 'Delivered')

How to find median in Excel
Median is the middle value in a group of numbers, which are arranged in ascending or descending order, i.e. half the numbers are greater than the median and half the numbers are less than the median. For example, the median of the data set {1, 2, 2, 3, 4, 6, 9} is 3.
This works fine when there are an odd number of values in the group. But what if you have an even number of values? In this case, the median is the arithmetic mean (average) of the two middle values. For example, the median of {1, 2, 2, 3, 4, 6} is 2.5. To calculate it, you take the 3rd and 4th values in the data set and average them to get a median of 2.5.
In Microsoft Excel, a median is calculated by using the MEDIAN function. For example, to get the median of all amounts in our sales report, use this formula:
=MEDIAN(C2:C8)
To make the example more illustrative, I've sorted the numbers in column C in ascending order (though it is not actually required for the Excel Median formula to work):
In contrast to average, Microsoft Excel does not provide any special function to calculate median with one or more conditions. However, you can 'emulate' the functionality of MEDIANIF and MEDIANIFS by using a combination of two or more functions like shown in these examples:
How to calculate mode in Excel
Mode is the most frequently occurring value in the dataset. While the mean and median require some calculations, a mode value can be found simply by counting the number of times each value occurs.
For example, the mode of the set of values {1, 2, 2, 3, 4, 6} is 2. In Microsoft Excel, you can calculate a mode by using the function of the same name, the MODE function. For our sample data set, the formula goes as follows:
=MODE(C2:C8)
In situations when there are two or more modes in your data set, the Excel MODE function will return the lowest mode.
Java Program To Calculate Mean Median Mode And Range
Mean vs. median: which is better?
Generally, there is no 'best' measure of central tendency. Which measure to use mostly depends on the type of data you are working with as well as your understanding of the 'typical value' you are attempting to estimate.
For a symmetrical distribution (in which values occur at regular frequencies), the mean, median and mode are the same. For a skeweddistribution (where there are a small number of extremely high or low values), the three measures of central tendency may be different.
Since the mean is greatly affected by skewed data and outliers (non-typical values that are significantly different from the rest of the data), median is the preferred measure of central tendency for an asymmetrical distribution.
For instance, it is generally accepted that the median is better than the mean for calculating a typical salary. Why? The best way to understand this would be from an example. Please have a look at a few sample salaries for common jobs:
- Electrician - $20/hour
- Nurse - $26/hour
- Police officer - $47/hour
- Sales manager - $54/hour
- Manufacturing engineer - $63/hour
Now, let's calculate the average (mean): add up the above numbers and divide by 5: (20+26+47+54+63)/5=42. Easyconnect vpn for mac. So, the average wage is $42/hour. The median wage is $47/hour, and it is the police officer who earns it (1/2 wages are lower, and 1/2 are higher). Well, in this particular case the mean and median give similar numbers.
But let's see what happens if we extend the list of wages by including a celebrity who earns, say, about $30 million/year, which is roughly $14,500/hour. Now, the average wage becomes $2,451.67/hour, a wage that no one earns! By contrast, the median is not significantly changed by this one outlier, it is $50.50/hour.
Agree, the median gives a better idea of what people typically earn because it is not so strongly affected by abnormal salaries.
This is how you calculate mean, median and mode in Excel. I thank you for reading and hope to see you on our blog next week!

posted 16 years agoDefintion of 'mode' --> The mode of a set of data is the value in the set that occurs most often.
Chase-
So, you're trying to calculate the mode of a set of data, and you don't want to use an array. What have you tried? Where are you having trouble? What part are you not able to 'get'? We'd love to help you, but we're not going to do the work for you. If you'd like to post your code and specifically explain what the problem is -- we'd be more than happy to help you de-bug the problem and maybe even offer some alternative solutions. How's that sound?
In the mean time, Im moving this to Java In General (Beginner) forum, where I think its more appropriate. Good luck!

Now you have a handful of small problems:
How do you go through your input set?
How do you keep a counter for each number?
Where do you remember the highest counter so far?
Where do you remember the number that got the highest count?
And if you really want to blow your instructor away, show em this: http://www.cs.utexas.edu/users/moore/best-ideas/mjrty/index.html (Shucks, that only works if there is a MAJORITY number, I think)
Have fun! Don't take my word for that plain language algorithm. See if you can do better!

People here love to help, but i'm not sure what your problem is. just telling us 'it doesn't work' doesn't do any good. If the code isn't too long, you can use the code tags and post what you written so far, and someone will probably give you some suggestions.

posted 16 years agoi don't know what you mean by 'what system should he use'.
there really isn't a lot of math involved in figuring out the mode. you need to scan all the input values, and count how many times each unique value appears. for example, if the 10 input numbers are:
5,8,2,3,6,5,1,8,0,8
since 8 occurs more than any other number, the mode is 8. the only math involved is simple addition and doing some comparisons (i.e. is one value greater than another).
when you say 'he has the input wrote', is he saving all 10 input numbers, so they can all be accessed later? or is he incrementing a counter for each as it is input?
again, it's much easier to help if you POST THE CODE. there are probably hundreds of ways to do this, but without knowing what path you've started, everybody is just making blind guesses on how to help you get further along.

Stan James has already posted pseudocode for the algorithm you can use. Now all you need to do is change it into Java code.
If you still don't understand, please post the code you already have and what problems you've encountered in trying to implement the code. You should also try writing out an explanation, in your native language, of the steps you should take to find the answer. Perhaps it will help to do an example by hand. Then you can more easily see what steps are needed.
