In statistics, what is standard deviation and sample standard deviation? If a population of measurements has a mean of 2.45 inches and a standard deviation of 0.15 inches: What are the values at +/-3 standard deviation? How to compute the population standard deviation and sample standa...
Given a mean of 8 and a standard deviation of 0.7, within how many standard deviations of the mean do the values 7.7, 8.4, 9, 8, and 6.9 fall? The mean of a list of numbers is 16.7 and the standard deviation is 0. What does this imply?
Standard error can either be high or low. In the case of high standard error, your sample data does not accurately represent the population data; the sample means are widely spread around the population mean. In the case of low standard error, your sample is a more accurate representation of...
Psychometric tests are seldom used in isolation and represent just one of the methods used by employers in the selection process. The usual procedures for selecting candidates still apply. For example, a job is advertised and you are invited to send in your resume, which is then checked to se...
Yellow Beltsrepresent everyone else on the team. They're not immersed in the details of the project and therefore don't require the same level of Six Sigma training or skill. That said, though, Yellow Belts are essential. They do apply some elements of the Six Sigma methodology as they he...
The finding of high variability of different leadership behaviors within one leader across one week contrasts more traditional perspectives on leadership. These perspectives assume that leadership behaviors represent leaders' stable behavioral tendencies over time that are driven by stable leader characteristics...
Despite the improvement of exploration of the variability in differences, a limitation of the traditional Bland–Altman analysis is that it does not allow for exploring each measurement separately. Most of the time, as previously reported in the measurement theory, none of the two measurements can ...
Snow models can be classified into two main categories: models that represent snow cover conceptually and those where snow cover is represented physically. Conceptual models include those where snow melt is simulated based on a degree-day equation such as CEMANEIGE [9] or the model developed by ...

A two-tailed test is designed to determine whether a claim is true or not given a population parameter. It examines both sides of a specified data range as designated by the probability distribution involved. As such, the probability distribution should represent the likelihood of a specified outc...
