The phrase “the ratio of the difference between the observed count and the expected count to the standard deviation of the expected count” sounds like a tongue twister, but it’s actually easier explained with an equation. One issue with the above calculators is that they are biased estimators. Troll Station follows a different local time during parts of the year. Whether seeking admission to a high school, college, or graduate program, or attempting to obtain a professional license or certification for a trade, it is difficult to achieve such goals without sitting for some kind of standardized exam or high-stakes test.
