What is the F ratio test and how is it different from Chi square square test?
A F-ratio test compares 2 variances and tell if they are significantly different. A Chi-square test compares count data.
56 is 64 percent of what number?
lets see...lets apply a simple ratio... (56/f) = (64/100) 64(f) = 5600 87.5 = f = your answer O.O

What is phenotypic ratio?
It is the ratio of physical characteristics of parents and the potential offspring traits. It is the ratio of physical characteristics of parents and the potential offspring traits.
What is F ratio?
Computing F-ratioThe F-ratio is used to determine whether the variances in two independent samples are equal. If the F-ratio is not statistically significant, you may assume there is homogeneity of variance and employ the standard t-test for the difference of means. If the F-ratio is statistically significant, use an alternative t-test computation such as the Cochran and Cox method.

Is the f distribution negatively skewed?
In general the distribution of F-ratio means what
What is F-ratio?
The F-ratio is a statistical ratio which arises as the ratio of two chi-square distributions.If X and Y are two random variables which are independent and approximately normally distributed, then their variances have chi-squared distributions. The ration of these chi-square distributions, appropriately scaled, is called the F-ratio.The F-ratio is used extensively in analysis of variance to determine what proportion of the variation in the dependent variable is explained by an explanatory variable (and the model being tested).
Possible to obtain a negative value for an F-ratio?
no.
What is the actual ratio of the phenotypic characteristics red 93 white 36?
The ratio of red to white phenotypic characteristics is approximately 93:36, which simplifies to 31:12 when divided by their greatest common factor of 3.
