in statistics, a confidence interval is defined as an interval estimation, and it calculates the probability, where the parameter that falls between the two sets of values. it measures the degree of certainty or uncertainty in the sampling method process. most of the time, the confidence ...
In statistics, a confidence interval (CI) or confidence bound is an interval estimate of a population parameter. Instead of estimating the parameter by a single value, an interval likely to include the parameter is given. Thus, confidence intervals are used to indicate the reliability of an ...

You can adjust the statistical calculations during a Positional Accuracy Assessment session by modifying the confidence level. This is the level of confidence for the evaluation layer. The value for this field can be 90, 95, or 99. The statistics are recalculated appropriately when this value is...
Z value. This can usually be done with a table in an appendix of a statistics text book. For reference, the Z value for a 95 percent confidence level is 1.96, while the Z value for a 90 percent confidence level is 1.65, and the Z value for a 99 percent confidence level is 2.58. ...
Before we can truly understand what a confidence interval and level really are, we must delve into some important background terminology. In statistics, there is something called the point estimate. A point estimate is the value of a sample statistic (such as the sample mean in our lesson)...

The overall calculation for the Upper Limit and Lower Limit is given below. For 90% Confidence Interval= (3.30 – 1.645 * 0.5 / √100) to (3.30 + 1.645 * 0.5 / √100) Confidence Interval=3.22 to 3.38 Therefore, the Confidence Interval at a 90% confidence level is 3.22 to 3.38. ...
