For example, 12-month price-to-earnings multiples in India are above 18 times, more than one standard deviation over their long-term median, indicating markets may be frothy and vulnerable if the central bank misreads inflation data and cuts interest rates aggressively, potentially fuelling a bubble.

"It's the longest half-life ever measured directly," Ph.D student Chiara Capelli from the University of Zurich who works on XENON told GizmodoResearchers aren't calling their results a "discovery," because their statistics didn't hit the five-standard deviation threshold particle physicists require in order to use that word.

More can be done with your database, such as better identifying outliers: If a backlog item lies significantly outside the standard deviation of time needed for comparable backlog items, you could study these cases in depth to identify hypotheses about important influences in order to inform future practices.

At this juncture, the S&P 500 is more than one standard deviation below its 50-day moving average for the first time since just before the U.S. presidential election in November, a typical indicator of "oversold" conditions, Raymond James market strategist Andrew Adams wrote to clients Monday morning.

Using Bollinger Bands to make trading decisions has a few obvious problems: They generally don't include enough periods to lend any statistical significance, the non-normal distribution of market returns means that standard deviation measures are of limited use and there is no evidence that a Bollinger Band-based strategy outperforms buying and holding.

As they describe in a paper in PsyArXiv Preprints, Sean Wilner and his colleagues at the University of Illinois at Urbana-Champaign have come up with a way of reconstructing, given the mean, standard deviation and number of data points in a result (all three of which are usually stated as part of such a result), all the possible data sets which could have given rise to that result.

If you go looking for bigotry as your explanation for every difference you see — you can read about this in Reich's book — if you have populations that have their means slightly different genetically, 80 percent of a standard deviation difference, you're going to see massive difference in the tail ends of the distribution, where you could have 100-fold difference in the numbers of individuals who excel at the 99.99 percent level.

At the Brookings Institution, Gershenson summarized some of the findings, based on surveys of kindergartners and school districts that experienced more snow days: Students who experienced more school days between the fall and spring tests made significantly larger achievement gains than their peers who experienced fewer schools days between tests [...] An additional month of schooling would increase the average student's achievement by 12 to 15 percent of a test score [standard deviation], which is similar in magnitude to the impacts of other potential education interventions.
