 `In ANOVA, what does F=1 mean?`
 ```F=1 means that the variance of means (factor) =variance of the error. The F distribution is the distribution of the ratio of two estimates of variance. It is used to compute probability values in the analysis of variance. The F distribution has two parameters: degrees of freedom numerator (dfn) and degrees of freedom denominator (dfd). The dfn is the number of degrees of freedom that the estimate of variance used in the numerator is based on. The dfd is the number of degrees of freedom that the estimate used in the denominator is based on. The dfd is often called the degrees of freedom error or dfe. In the simplest case of a one-factor between-subjects ANOVA, see http://davidmlane.com/hyperstat/A107688.html but in fact F is used to compare between the calculation and the tables to see if your hypotesis should be accepted or rejected.```
