Somehow I missed all the surveys.

23, but 24 in less than a month, so do with that as you will

My 5th grader is learning average, median and mode. I understand average, but what is median vs. mode? And, will this be on the test?

I'm 20.

Still feel like I'm 17 though.

Also is below 21 ages 18-21? and same for 21 and up? 21-30 years old and so forth?

This is a cool project. Based on this data, values of manual wagons and Miata's are going to skyrocket in 5-9 years once the 21-30 y/o's get some disposable income.

nope, everything is exactly as it says, anything 21 and below, anything 18 and below, anything 30 and up and so forth.

To get 40 to 50, just do 11-4=7 people are age 40 - 49.

Mean is the average. Median is the middle number. Mode is the most frequent number. :)

just to clarify, to get 21 - 29, you have subtract the 30 and up, so that makes 89-44=45 people.

Nice, I like reading statistics, but only do them when needed. It would be nice if you do something else, like what is the average fuel efficiency of the Oppo car fleet.

Another 21-29 here. I'm 22 to be more specific.

davedave1111 > ttyymmnn
11/20/2013 at 16:37

I was only half-joking. The median is the middle value, so the strip down the middle of the road being called the median helps remember.

I'm guessing a fifth grader's a bit young to understand the link between la mode and the mode being the most 'popular/fashionable' number in the list.

What helps with all this kind of thing is if you actually understand why, rather than just trying to remember definitions. When I was at school the sets of numbers they demonstrated with were really dumb, leaving me wondering why you'd use any average other than the mean. When you have a situation where it's actually appropriate, it makes much more sense.

A good example is the average number of wheels on a car. The mean is a hair under four, because there are a few three-wheelers out there, and so-on, but nearly no cars with more than four. The mode, though, is four. If you're a wheel/tyre manufacturer, and want to know how many tyres to package in a set, it's the mode that's useful to you, not the mean.

That's a great description, since I have always wondered why those other measurements would be useful. Thanks.

I read your reply to my son, who sort of understood, but something caught my attention that I missed the first time I read it. You wrote,

leaving me wondering why you'd use any average other than the mean.

and it struck me then that mean, median and mode are all averages. I was always under the impression that mean and average were the same thing. So if I read you correctly, mean is a type of average, in the way that median and mode are also types of averages.

Normally when people say average, they mean the mean, but in fact there are lots of types of averages - many more than just the three common ones.

Statisticians talk about a 'central tendency' of a data set, but what they're actually on about is simply the most typical item in a list - the one that best represents the whole list.

Obviously, what is 'best' depends on why you're trying to generalise the results in the first place.

There's a whole list of different averages here:

http://en.wikipedia.org/wiki/Measures_…

It's not exhaustive, by any means. The point of some of them is more obvious than others.

" Truncated mean – the arithmetic mean of data values after a certain number or proportion of the highest and lowest data values have been discarded."

That one's relatively easy to imagine a use for. Say you wanted the average of the tyre profiles people use, but you wanted to know what was typical, so you excluded the stancers with ridiculously stretched tyres at one end, and the mudders with huge off-road tyres at the other.

Wikipedia actually has a decent explanation for why you might use the geometric mean:

For example, the geometric mean can give a meaningful "average" to compare two companies which are each rated at 0 to 5 for their environmental sustainability, and are rated at 0 to 100 for their financial viability. If an arithmetic mean was used instead of a geometric mean, the financial viability is given more weight because its numeric range is larger- so a small percentage change in the financial rating (e.g. going from 80 to 90) makes a much larger difference in the arithmetic mean than a large percentage change in environmental sustainability (e.g. going from 2 to 5). The use of a geometric mean "normalizes" the ranges being averaged, so that no range dominates the weighting, and a given percentage change in any of the properties has the same effect on the geometric mean. So, a 20% change in environmental sustainability from 4 to 4.8 has the same effect on the geometric mean as a 20% change in financial viability from 60 to 72.

Another average you might be familiar with from amps and stereos and so-on is RMS. That's used with electric current because AC is positive half the time and negative half the time, so the mean would be zero. RMS turns all the values positive, so gives the result you'd naturally think of as the average electric current in the system.

One thing that maybe isn't obvious is that you might use different averages on the same data, when looking at different things.

Imagine you're a company with a load of clients, and you do a customer satisfaction survey. You could just take a straight-up mean. If you wanted to take into account that some clients were bigger than others, you could use a weighted mean, where you multiply their satisfaction score by their bill. If you wanted to just analyse the middle-ranking clients, you might go for a truncated mean.

At the end of the day, all statistical techniques are just ways of looking at a big pile of data and trying to summarise it. How you summarise it depends on what you want the summary for.
