Rounding Data
The result of rounding off a number such as 72.8 to the nearest unit is 73, because 72.8 is closer to 73 than at 72. Similarly, 72.8146 rounded to the nearest hundred or two decimal position is 72.81, because 72.81 72.8146 closer to than to 72.82.
In rounding off the nearest keratusan 72.465, we are faced with a problem as far as 72.465 from 72.46 and 72.47. Has become the custom in such cases...
Requirements for Data Analysis
Nonparametric test is used when the assumptions of parametric tests are not met. The most common assumption in the parametric test is a random sample from a normally distributed population, the data is homogeneous, and linear. If these assumptions are met, or at least a little deviation to the assumption, then the parametric test is still reliable. But if the assumptions are not met then an alternative...

What level of Significance and Confidence Levels?
In the discussion the term statistical significance level (significance level) and level of confidence (confidence level) and is often used.
The level of significance (alpha) indicates the probability or the chance of errors set of researchers in making decisions to reject or support the null hypothesis, or can be defined as well as error rates or error rates are tolerated by the researchers, is...
The Concept Degrees of Freedom
The term number of degrees of freedom (degrees of freedom) is defined as the total number of observations in the sample (= N) minus the number of control (linear) free or limitation (restriction) is placed on earlier observations. In other words, the number degrees of freedom is the number of free observations of a total of observations N. So the general formula for determining the degrees of freedom...
