25 Numbers Journalists Should Know

25 Numbers Journalists Should Know
A few days ago, I asked friends and colleagues on listservs to suggest
25 relatively generic numbers journalists should know in order to be
responsible, effective reporters and editors. You sent along the great
suggestions included below. A handful of folks, however, responded to
make two points:
· It is more important to know where to find pertinent numbers than it
is to know specific numbers, and
· It is more important to know appropriate calculations – say, how to
compute percent of change – that can be applied to specific numbers once
they are found.
Yes, points well taken. But I don’t think any of these are mutually
exclusive. Here’s why.
Any statistical analysis begins with classifying and counting. That
process is only relevant if put in some context. If I tell you that
Santa Fe, New Mexico has about 68,000 people, that number by itself has
little meaning in terms of scale. Is 68,000 big or small? How do I
tease some information out of that lonesome statistic? Ah, but when we
can ask how does it compare to other cities in the state, region or
nation meaning and information start to bubble up?
The second analytic step is estimation. This is helpful – perhaps
necessary - to have some ballpark figure to help the analyst determine
if his/her calculations are correct or “make sense.” If the city
manager tells a reporter that the town has been growing by about .5
percent per year since 2000, she could not estimate the amount of growth
or its current aggregate unless she had a baseline number of 68,000.
So we think that (a) journalists should always have some relevant –
and fairly accurate – ballpark figures in mind to help with context
(Yes, some of these will vary from beat to beat); (b) journalists should
know where and how to find the historic and current statistics; (c)
journalists should know how to do some fairly elementary arithmetic to
tease information out of the data.
Thanks to all for your contributions.
