Explain Mode, Median, & Mean. Give examples and any references.?

Mode is most occuring. I always remember it because like M for most and O for occuring. \n1 3 4 4 4 4 4 5 6 6 6 \n \n4 would be the mode\n\n\nMedian is like middle number. median.. middle. they just kinda go together. you line them up in order then cross the end ones off until there is only one left. if there are two of them left then add them up and divide by two.\n \n2 3 4 5 6 7 8\n \nfive would be the median\n\n\nMean is average. i always remember it by ME Average? haha kind of doesnt make sense but hey it works for me. thats when you add all the numbers up and divide the sum by how many numbers there are \n\n1 2 3 4 5 6 \n\nso 1+2+3+4+5+6 = 21 / 6 =  3.5\n\nso the mean is 3.5

Mean: 113\nMedian: 108-116\nMode: 108-116\n\nThe mean was the hard one, I actually took the middle score from each range (eg 90-98=94) and multipled it by the number of times it occured (eg 94x6=564) and added all 5 (564+2266+4816+3388+1170= 12204). Then divided it by the frequency (6+22+43+28+9=108). Total (12204/108= 113). It's impossible to find a mean of a set of ranges, you need exact figures.\n\nThe mode is the most commonly occuring range, the median is the central range. These figures can't be accurate without the full actual IQ scores. But based on the figures provided, the mean, median and mode are as I stated above. If you provide the exact figures I'll work out the exact mean, mode and median.

You put the numbers from least to greatest.\nthen you get to the number that is in the middle of the set. (it's easy to do this by crossing off the numbers on the outsides till you get to the middle)\n\nStep A) 23, 25, 26, 30, 37, 39\nStep B) 25, 26, 30, 37\nStep C) 26, 30\n in this case you have 2 middle numbers, so you average them (add them together, divide by two)\n26+30=56\n56 divided by 2 is\n28\nSo yes, 28 is your median.

To elaborate further, your mode does tell you what the most common value in your data is, but, like the median, it's a somewhat arbitrary value.  For example, take the data set 1,2,2,3,7.  Both the mode and the median are 2, and the mean is 3.  Now take the data set 1,2,2,25,50.  Again, the mode and the median are both 2, but the mean is now 16.  Now, say that second data set represents the number of shark attacks that have happened in the past 5 years off the coast of a beachfront property you're thinking about buying.  I'd much rather know the mean number of shark attacks, not the mode or the median, wouldn't you?

Take the average of the absolute value of each of the numbers minus the mean...\n\n( |2.44-2.23| + |3.54-2.23| + |1.37 - 2.23|  + |1.5 - 2.23| + |2.3-2.23| )/5

Hi! I'm a statistician and I use http://www.statsoft.com as well as cheap textbooks from Half Priced Books in my area. Both seem to help. If you have a specific question, feel free to email me. Don't know how much good I'll be because I use fancy software for my analysis, but I'll try.

nothing, mean is just a different word for average.  the median and mode have different meanings though.  the median is the number right in the middle of all the data, the range is the lowest number to the higest number in the data, and the mode is the number that occurs most often.\n\n"bradsgranny" down there is COMPLETEY wrong, the MODE, like i said, is the number that occurs most often, not the mean...people should check their sources before they write something that is entirely WRONG.

Descriptive Statistics do no intend to "fit" a distribution on the data or to predict new observations given the data.\nInstead, it pretends to "describe" the data in terms of its central tendency measures (mean, median, etc.) as well as dispersion statistics (variance,  rank, inter-quartile rank, etc.), bias statistics, etc.\nSummaries like histograms are also a good example of descriptive statistics.

Is this for homework?? Well anyways, I had math MCAS today and that was on it. As you see the others have already answered so I have no need to type it all over again. But I will anyways. The range is the difference between the largest and smallest numbers like. 2, 4, 6, 6, 7, 8, 9, 9, 10, 12. You would do 12-2=10. For the median you would put the numbers in order greatest to least. Like if it was this:6, 7, 4, 2, 6, 9, 12, 8, 9, 10; you would make it this:2, 4, 6, 6, 7, 8, 9, 9, 10, 12 and then cross them off like in pairs like 2 and 12, 4 and 10, 6 and 9, ect. until you get to the middle. The median is the middle number. If you have an even amount and there's two in the middle(like in my example) you would put down the halfway point between both numbers. Like for 7 and 8, the answer would be 7 and a half; for 7 and 9 it would be 8; and so on. I hope I have helped with this incredibly long message.

range=highest value-lowest value\nthere are three averages\nmean is total of all the items/no of items\nmedian is the middle value\nmode is the most repeated value

Median is the "resultin the middle" Mean is the average of all results\n\neg:  7 results:\n\n\n1  2  1  9   9   9   9\n\nThe Median is 9\nThe mean is 5.7\n\nIncidentally the modeal is the numberthat occurs most - eg:\n\n1  2  5  5  3498  2323\n\nThe modal of this is 5 - the only number in fact which appears more than once. As you can see, except in VERY odd circumstances, the modal result is grotesquely misleading as an "average"\n\nHaving explained some of your question, I will let others answer the other bits, you multiple-askers you :)

The Mean is the average.  You have 22 numbers; add them up and divide by two to get the mean.  In this case, that gives 87.38\n\nThe median is the "middle" value.  Since you have 22 numbers, 11 of them will be below the median, and 11 will be above.  In your case, the 11th biggest number is 87.9 and the 12th biggest number is 88.  The median could be anything in between, but is generally taken to be the average of these two- or 87.95\n\nThe mode is the most common value.  In your case, each value occurs only once, except for 91.7 which occurs twice.  Therfore, 91.7 is the mode\n\nUpper and lower quartiles are similar to the median; The lower quartile is the value below which 1/4 of your values lie, and the upper quartile is the value above which 1/4 of your values lie.  Since you have 22 numbers, the lower quartile is the value between the 5th and 6th largest numbers (82 and 83.6), and the upper quartile is the value between the 17th and 18th largest numbers (92.9 and 94.2).  That makes 82.8 and 93.55\n\nThe range is the minimum value to the maximum value, or {68 to 98.2}\n\nTo get the variance, first subtract the mean from each value.  Then, take the square of each of these new values.  Then, add up all these squares.  Finally, divide this sum by the number of values (22 in your case).  This should give a variance of 51.22 with your numbers.\nNOTE:  The above formula is for "population variance", and is generally used when your numbers represent an entire population.  If your numbers represent a sample of a population, you should use the "Sample Variance", which has the same formula except that you divide by the number of values minus one (21 in your case).  With your numbers, this should give a sample variance of 53.66.\n\nThe standard deviation is just the square root of the variance.  Like the variance, there is a "population standard deviation" (7.16 in your case) and a "sample standard deviation" (7.33 in your case)

As far as I understand average and mean are the same thing.  Average is adding up the numbers in a set of data and divinding by the number of numbers you added up.  Example: 3, 6, 3 add up to 12, divide that by 3 and your average is 4.  The mode is the number that appears the most often.  In the set of numbers I gave as an example 3 is the mode.  Range of data is finding the difference between the highest and lowest number.  In the set of numbers above I would take 6 - 3 = 3. so three is the answer.  Good luck!

the mode of a set of numbers is the number that occurs most often.  for example, in the set 2, 4, 5,8, 8, 9, the mode is 8, as it occurs twice and the others only once.  another example: 7, 9, 9, 2, 5, 5, what is the mode?  there are actually two, 5 and 9, because the both occur the most.  if all numbers occur the same number of times, then there is no mode.\ncheck your math book and ask your teacher for more explanation.\nall you have to do is count the numbers, some people find that it helps to put them in order, so that they can be sure not to miss any. (instead of 7, 9, 9..., rewrite as 2, 5, 5, 7, 9, 9, this is also helpful when doing mean and median)\ngood luck on your work!  i like that you didn't include the actual problem, that shows that you really want to learn, not just take the easy way out.

Hi,\n\nA fitted value is the mean (Average)\n\nOf a statistics, I know it's confusing sometimes!!\n\nCheers!!\nHope that helps!!
