What does F ratio mean?
Also know, what is the F ratio?
The F-ratio is the ratio of the between group variance to the within group variance. It can be compared to a critical F-ratio, which is determined by rejecting or accepting the null hypothesis, which determines whether or not there are no differences between groups.
Also Know, can F value be less than 1? The short answer is that F is < 1 when there is more variance within groups than between. If F value is less than one this mean sum of squares due to treatments is less than sum. of squares due to error. Hence, there is no need to calculate F the null hypothesis is true all the samples are equally significant.
Simply so, what does a high F value mean?
If you get a large f value (one that is bigger than the F critical value found in a table), it means something is significant, while a small p value means all your results are significant. The F statistic just compares the joint effect of all the variables together.
What does an F value of 1 mean?
The F-distribution is used to quantify this likelihood for differing sample sizes and the confidence or significance we would like the answer to hold. A value of F=1 means that no matter what significance level we use for the test, we will conclude that the two variances are equal.
