# How far can common sense take us in the field of data?

Can you put a number on that?
How far can common sense take us in the ﬁeld of data? At ﬁrst glance, not quite. The discipline
Might be vital but it’s also highly technical, and filled with pitfalls and counterintuitions. Statistics may feel like numerical alchemy, incomprehensible into muggles– black magic, also.

This will not do. If we’re ready to go with our brains rather than with our courage, any people may think clearly about the world by using statistics. And since a lot of the world– from US electoral polling information to the spread of Sars-Cov-2 into the expectation of economic recovery — can reliably be perceived through a statistical individuality, that’s just too.
A useful ﬁrst step is to ﬁnd out what exactly the numbers are measuring. For instance: some studies suggest that playing violent video games causes violent behaviour. Before you leap to overeat — or deny — this conclusion, ask yourself whether you know what’s being claimed. What’s the deﬁnition of a violent video game? (Pac-Man devours sentient monsters, which seems violent. But maybe the researchers had something somewhat edgier in your mind )
To proceed into the question of real- world violence: each time there’s a mass shooting in the united states, we are reminded that almost 40,000 people there are killed by guns each year. It’s a shocking number — but a number of these deaths occur during mass shootings, and more than half have been suicides. The problem is huge and pressing, but it isn’t always the problem that we assume.
Such questions suggest that the topic of data is even more confusing than we believed. Perhaps this is accurate, but there’s nothing particularly technical about the replies. These are questions about the planet and the words we use to describe it. There’s not any jargon here.All we want is some curiosity about what lies below the numbers.
And if we don’t have any curiosity,I am not sure there’s a cure for it. The next step is more fun: faced with a statistical claim, ﬁnd
A means to put it into context. Is it going up or down in comparison to last week, or last year, or even a decade ago? Is it big or little, compared with something more familiar?
Not all such efforts make sense. The bigger the debt, the larger the pile. This might help to create a sense of alert but it does not do much for clarity.
In 2011, NPR’s”Weekend Edition” attempted to exemplify that the US federal debt by stating,”If you stack up 14.3 trillion dollar bills, the heap would stretch to the moon and back twice.” That does not help. Really, it’s triply unhelpful, since most of us lack an intuitive grasp either of how far away the moon is of how many dollar bills there are into the lawn, and even if we’d both we’d still be stuck with the question of if \$14.3tn was a worryingly big debt or not.
More useful would be to consider about their debt as a sum per individual. In the conclusion of 2019, US federal debt was nearly \$23tn, which will be about
\$70,000 per US resident.I do not know if that is less or more alarming than attempting to measure it out in excursions to the moon but it is surely significantly more enlightening. A couple of moments witha search engine and a calculator will tell you this works out as 30 pence per person in the UK per year.
Everybody should familiarise themselves witha few standard truth about the world. If you understand the population of this country you live in, or it is about 3,500 kilometers from London to New York, you can utilize these landmarks to orient yourself if limiting a statistic for your ﬁrst time. When you meet a strange amount, ” says Matt Parker, the author of Humble Pi, you can use these more familiar numbers to make a debut so that you understand the stranger.I love that way of putting it, not least because it suggests that each number is a potential friend instead thana traitor waiting to become exposed.
I’m all in favor of expertise,such as statistical experience. But in most cases it is neither necessary nor suﬃcient.
