Anyone notice the smell in town the last week? Went for a walk a couple of evenings as I live close by and it was just awful, like before the main drainage scheme.

I did come across a couple of people openly pi55ing on Patrick St so maybe that and the heat had something to do with it.

I've gotten a stagnant water smell and sometimes a sewage smell around the place the last couple of weeks, alright.

More likely that due to the shutdown, combined with the dry weather, drains aren't getting their normal water flow to flush them through .

Do engineers "love it"?

There is a plane, due to take off, it has 50 passengers. The passengers consist solely of couples with young children.

The pilot is worried about the weight limits, now which do you want, your beloved median or the not very representative mean?

I never said that engineers *only* use median. Of course average/mean is used as well, perhaps more so. It really depends on the context. In some contexts median is more useful. For example, in my own business, the median size of a file on a disk is more relevant than the average.

When it comes to a plane-load of passengers, load control calculations will work off average. Median isn’t so useful for weights of humans because the outliers aren’t so extreme. The average human weighs 62kg but the heaviest human ever was only 440kg (7x the average). In real estate though, while the average house price in Cork is €220k, there are lots of properties costing €2.2M (10x average) and even a few costing €22M (100x average). Median comes into its own when the outliers are more extreme and the distribution is asymmetric.

Median IS an average, as is the mean and the mode. There is no one 'average'.

I was just answering an earlier poster who claimed engineers love the median. This imo is just plain silly.

I love pizza too and I eat it all the time. And I’d be happy to explain to somebody newly arrived from Mars what pizza is. But that doesn’t mean that I only eat pizza or even that I eat it more than other foods. One does not need to be monogamous when it comes to foods and statistical tools.

I don't think that the median is the appropriate one to use in the current context.

My earlier post wasn’t claiming that median was more appropriate for the current context. I was just being nice and trying to clear up the confusion about what median was by using an example everyone could understand. Apologies for having upset you so much...

Jesus H Christ you can’t win. I originally wrote the above using the more technically correct word “mean” and deliberately re-wrote it to avoid sounding so engineery, and used the man-in-the-street word “average”. Again, apologies for having offended so many of you pedants with a well-meant attempt to explain the concept of median to those who didn’t understand it. FFS.

noticed this a few weeks ago - esp around Daunt Square - paul street..

i wonder is it because they are not allowed to hang out in hostels etc anymore either? due to social distancing? heard something on the radio about a lot of them only getting breakfast - then they have to get out - not sure though..
but I am wondering why they are so obvious now also - are they hanging around town more or is it that they are just more obvious as there are less people around?
in any event I feel sorry for them - the guards are flat out patrolling them

More obvious I'd say as the city centre footfall is gone,beggars ate bad enough,this TROLLOP about my own age ( I've 60)
calmy dropoed her drawers about 20 metres away from me yesterday on Carrigaline park,not as if she couldn't see me I was up on a strider machine, disgusting,yes she was partly covered on one side but all was visible to anyone near me

It's nice to see my inner pain in learning statistics played out on the Internet in all its glory.

And that was when I was twelve.

Really, estimate the mass of the 8 planets in the solar system, using the median mass.

This sort of grand all encompassing statement is just something :rolleyes:

The truth of the matter (which I think you can't disagree with) is that when distributions are highly skewed, point estimators are on their own are just not that useful at all.

Btw, thanks for the apology I guess, even though I think you called me a pedant in the next post. I can assure you, I only come on here to amuse myself when bored and don't take any of it to heart.

These examples don’t help you Timsey.

No, but non-essential outlets should be shut for the duration of the lock-down.

Crisps and chocolate are other non-essential goods, shut off those parts of the shop. Hell, if you're going by essential, let's just have a few loaves of bread, and some milk & water at the front of the shop, people will be in and out in seconds.

You same Hell-bent on misrepresenting what I’m saying. You can come up with all the clever examples you like of where median is an inappropriate or even useless stat and I won’t argue with you. I will just repeat that in certain scenarios it is the ideal stat, and - where it is available - I love it in those cases.

As an aside, your behaviour here is representative of the kind of thing that puts so many off participating in online forums. Somebody writes a well-meaning post to try to clear up some point of confusion for people who don’t have a technical background. The post is widely-thanked and presumably received by most in the spirit in which it was intended. But then along comes clever-boots who just wants to “amuse myself when bored” (your words) and decides to make obscure arguments that are not at all enlightening to the people originally confused. Why would anyone ever bother trying to help when they face the prospect of that type of pedantic BS? Over and out.

The lough absolutely packed today, people having picnics, kicking ball with their friends. Ive closed my business costing me a small fortune, playing by the rules, why can't others. Stay the **** inside the quicker this is over and we can enjoy our summer with little restrictions.

Really? They're the type that think they can't catch the virus.

In other words you are trolling?
Coz you either really don't understand anything about stats or when it is appropriate to use one method over the other or you are deliberately misrepresenting the obvious to troll people.

I'll give you the benefit of the doubt on trolling and day you just don't have a clue what you are talking about.

No. I live in the city centre. This is not the usual.

Also.
Shall we move on from the stats?

Got a lot better since they stopped the Lee being an open sewer 15 years ago.

On Easter Sunday, I think they're all closed.
Tesco and Lidl are definitely closed.

Aldi was open on St Patrick's day so, maybe.
Edit, Aldi closed, too.

Most tesco are open from what I know. Aldi and Lidl all closed.

Tesco and Supervalu open according to another thread.

Same with Mahon.
