The importance of "time" in analysis
by Brad Myrstol |
This short video is intended to help everyday people interpret basic crime statistics. In this video, data on rates of larceny theft in 熊猫在线视频 for 1985鈥�2016 are used to demonstrate the importance of time in analyzing whether crime is trending upward, trending downward, or remaining flat. If we use short timeframes (one year, five years), we would conclude that larceny theft rates in 熊猫在线视频 have gone up. But if we use longer timeframes 鈥� 10 years all the up to 30 years 鈥� our conclusions change: larceny theft crime in 熊猫在线视频 has actually decreased over over the 30-year period from 1985 to 2016. Using longer timeframes, we see that cime rates fluctuate up and down over time, and we're also able to make more accurate judgments of long-term trends. If our timeframe is too short, we run the risk of reaching faulty conclusions about crime trends. A transcript of this program is available.
