What is an f ratio in statistics?
frequentcy
The F-ratio is a ratio of what?
Applied to focusing lenses and mirrors, including telescopes, binoculars, and cameras, the focal ratio or 'F-number' is (the focal length of the lens or mirror) divided by (its aperture or diameter)
Define measurement and characteristics of measurement?
Define these Levels of Measurement.NominalOrdinalInterval/Ratio
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.
What are the defining characteristics of the Ratio Level of Measurement?
Equal intervals between points of that scale and a true zero
What characteristics of a ratio define it as a rate?
When the second element of the ratio is 1.
In analysis of variance the magnitude of the mean differences from one treatment to another will contribute to the numerator of the f-ratio the denominator of the f-ratio both neither?
the numerator of the F-ratio
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 the actual ratio of the phenotypic characteristics red 93 white 36?
Monohybrid ratio i. e. 3 : 1
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).
Define measurement and characteristics of measurement?
Define these Levels of Measurement.NominalOrdinalInterval/Ratio
Possible to obtain a negative value for an F-ratio?
no.
What is the RPM suppose to be at when accelerated 100km?
That is dependant on the ratio of the differential. The ratio is usually selected by the automotive engineer who is calculating the performance requirements and engine displacement/torque along with maximum and nominal engine RPM. It can be as low as 1800 RPM and depending on the engine characteristics, the engineer could have determined that it should be 3500 RPM or more.
