I just read this and found it interesting!!

Pay close attention to the last few paragraphs. I think someone has finally began to figure out a few things. Also there is a link about Obama's actions doing next to nothing to help.

The average median time for police to respond to these incidents (where data was available) is three minutes.

 

 

WTH is "Average Median" ??

“This tells us that citizens and bystanders have a very real and active role in stopping these events,” Nichols said. “If we can properly prepare and educate civilians, maybe we can get to where 90 percent are stopped by civilians long before the police arrive.” Interesting.....

I found it very interesting also jacob. All this time they have been preaching gun control and now all of a sudden they are realizing that citizens that are on the scene when i begins can end it much faster with much less lives lost. Note how careful they were to not mention armed citizens but the story pretty much speaks for itself what they are talking about..............jmho

[jacob]

The story was blatantly a statist, anti gun piece...The writer must have brain farted when he included that little tidbit...kinda made the whole pro 2A point 2 sentences. ...

[bersaguy]

yea but being a  pro gunner guy anyone that is pro gun can see the real point of those few sentences. Had it not been for those couple of sentences in it I would not have posted it.........jmho

[jacob]

I understand....There is always a moment of truth in a lie...

WTH is "Average Median" ??

The "Median" is the number in the middle of a range of values. i.e. in {1,3,5,7,9} the Median is 5 because it is in the middle of the set. In a range of values with an even number of values there is no technical median so one must be calculated. This is done my attaining the mean(average) of the two middle most numbers in the series and is often refereed to as an "Average Median" i.e. in the set {1,3,5,7,9,11} the "Average Median" is 6 and is refereed to as such since it is the mathematical center of the set of numbers but not a member of the set itself.

 

 

Since there were 110 active shooter events studied, there may have in fact not been an actual event in the study with a 3 min. response time so they are letting you know it was calculated from the two center most response times in the set.

I will readily agree with your explanation of how to calculate the median for a data set that has an even number of elements, but in over 30 years of studying and teaching mathematics, I have yet to see "average median" used in that context.  Maybe this is something new?

Unfortunately, there is no statistical term as they describe.

 

Taking the average of the two center values (and only if an even set of values are indicated) is still only - the median.

 

It matters not how they calculated the median (by center value, or average of two closest to center), the statistical term is still the same.

 

It just shows that the writers and editors do not understand the information before them.

 

Heck, they could have printed the mode and made just as much sense.

... I guess using the term "interquartile range" correctly would be completely out of the question then? ;)

[npgunner]

Let's follow the logic ... 

 

"the study found that almost half of the active shootings are over before officers arrive"

 

so let's offer new training to lots of officers ... 

 

then present a story where an armed officer ALREADY STATIONED AT THE SCHOOL may have prevented a shooting getting worse as evidence that the training is likely to work ...   :screwy:  seems to me, we should be promoting officer training and placing more armed guards at the school; maybe the NRA is on to something

 

for what it's worth ... i do like that the story points out that citizens can have an active role in these situation, but wish they promoted a more active role then "run, hide, [then] fight [as a last option]" and that the story at least mentions that someone with a gun may have prevented a situation from getting worse

I know im going out on a limb but maybe it's an average of average response times from different agencies.

It's a statistic by the statistician that went hunting with that Biologist and the Chemist.

When you build a model based on fear, not on actual data, and you build an infrastructure to perpetuate it, you get the

current policing system we have today. SWAT teams are a necessity, just not for every street corner. That ALLERT training

thing seems to be a step in the right direction if it is meant for your every day cop. It used to be that there were no SWATs.

Cops were all there was. Laws get in the way they conduct themselves, and some court decisions go as far as saying they

are actually not meant to protect and serve. I'd say cops have a rough job ahead, with each shift, somewhat like the laws

us citizens have to face not knowing whether we are criminals or not.

 

We expect too much from the police, and they have too much crap to keep up with as well. I don't envy them, at all. That

Sheriff's Deputy who effectively stopped the latest school shooting showed that time is the issue. Get rid of the gun free

crap and empower the citizen, once again. Give the cop the right tools to do his job and quit militarizing.

[Guest theconstitutionrocks]

OF COURSE they didn't include drug deals and gang activity. Doing so would have forced them to admit that, while there may be fewer casualties per incident than mass shootings, the number of those are so high that the total casualty count is enormous.

 

I kind of look at this like plane crashes. When they happen they are usually VERY bad with high or total loss of life, but they are also EXTREMELY rare (at least here in the US). The same can be said for lightning strikes or tornados. I think this is a solution in search of a problem and just one more tool being used by the antis to push their agenda while selectively ignoring the much larger and more pressing issue of gang violence.
