In our first class we looked at how journalists started with no data and figured out a way to answer the question they had
In our second class we thought about where to find data that was the basis of a newspaper column.
Today we're looking at the data that exists, but upon closer inspection, seems to be innacurate through miscounting or possibly blatant manipulation.
In the year 2009, the Baltimore police reported 158 rapes.
First question when presented a number is asking: how significant is 158?
Like we did when we analyzed homicide numbers, the easiest way to check is to put the number in historical context.
Compare 2009's 158 rapes with years before it.
Just looking at the prior decade, it looks like 158 is in the norm since 2002.
However, there is a noticeable drop since 2000.
It looks like Baltimore's seen a drastic drop since the '80s and '90s.
A high of 749 in 1992 compared to 159 in 2009?
That's an 80 percent drop.
Is that significant in context?
Where should you go?

Look up rape stats US-Total for 1992 and 2009 just like Baltimore.
FORMULA CHECK
How do you calculate percent change?
(Value 2 - Value 1/ Value 1) * 100 = Percent Change
According to the FBI, there were 109,062 rapes in 1992 versus 89,241 in 2009.
So (109062-89241/89241) x 100 = 18 percent drop.
If Baltimore's population shrank by 80 percent, that would explain the 80 percent drop in rapes. Google it.
What if Baltimore PD just got really good at their jobs?
How would you check that with data?
What could you compare?

Formula time.
Ratio is Rape/Murders.
Where does Baltimore rank?
Baltimore's rape to homicides statistic is so low that it's one of the few cities in which there are more homicides than rape reports.
More homicides than rapes: Nationally, there are five rapes for every murder committed. Out of 272 cities with a population of 100,000 or more, Baltimore is one of five recording more murders than rapes in 2009.
If the number of sexual assault reports had really dropped, then the reports detectives would drop, but also the calls reporting them.
The Sun couldn't get the number of 911 calls tied to rapes before 2003, so can't see if there's a correlating drop in reports.
However, they were able to get more specific details for timeperiod of data they got, revealing:
that four in 10 calls to 911 during [the past 5 years] never made it to detectives specializing in sex crimes, having been dismissed by police officers at the scene with no report taken.
For the reports that eventually reached Baltimore detectives,
marked unfounded by detectives, meaning police believed the victim was lying.
Going back to at least 2004.
“Why is it that women in the greater Baltimore area are more disposed to lying about sexual assault than anyplace else in America?” asked Branson of Turn Around. “Is it in the water? What exactly would make us the ones most likely to tell a story about being sexually assaulted?”
Interviews with detectives: more “unfounded” reports was because of better police work.
Current and former sex offense detectives in Baltimore defended their investigations. Part of their mission, they say, involves rooting out illegitimate complaints that in the past would result in wasted effort and false arrests.
and
“The bottom line is, the case is only unfounded when the investigative facts prove the crime did not occur,” said Uzarowski, who retired from the department this month. “It's not an opinion. It's not anything other than where the facts fall.”
Dig deeper.
The reporter analyzed the rape report numbers by individual detectives.
The Baltimore squad that investigates sexual assaults and child abuse comprises 50 detectives. One of them, Detective Anthony Faulk Jr., is responsible for one-fifth of the unfounded reports, shelving 14 cases last year, including the alleged attack in midtown. No other detective had more than six such cases, and some have none. Attempts to reach Faulk through the department and police union were unsuccessful.
But it does raise some doubt about better police work being the answer.
If the drop was due to better police work, how can one detective affect such a lopsided rate?
Luck? He's doing a better job?
Or, as critics charge, no standard for evaluating rape claims exist thus making it easier for detectives to dismiss valid cases.
I can't tell you that we would have seen that by yourselves.
Rape is different from other crimes. Not only does it involve a violation more profound than any other crime but it also comes with a social stigma that forces victims to relive the pain again and again. No one suggests that a victim of a carjacking was really asking for it. No one asks whether an assault might really have been consensual. When a robbery victim is on the witness stand, the most private details of her life are not dissected under cross examination.
Look at that gap. How many valid accusations were dismissed? How many more would be ignored if not for the Sun's investigation?
All this data, some good, some unreliable, were accessible to all levels of authority.
But just because it's there doesn't mean it's known or understood.
