In statistics , the correlation ratio is a measure of the relationship between the statistical dispersion within individual categories and the dispersion across the whole population or sample. The measure is defined as the ratio of two standard deviation s representing these types of variation. The context here is the same as that of the intraclass correlation coefficient , whose value is the square of the correlation ratio. Definition Suppose each observation is y sub xi sub where x indicates the category that observation is in and i is the label of the particular observation. Let n sub x sub be the number of observations in category x and math overline y x frac sum i y xi n x math and math overline y frac sum x n x overline y x sum x n x , math where math overline y x math is the mean of the category x and math overline y math is the mean of the whole population. The correlation ratio eta letter eta is defined as to satisfy math eta 2 frac sum x n x overline y x overline y 2 sum x,i y xi overline y 2 math which can be written as math eta 2 frac sigma overline y 2 sigma y 2 , text where sigma overline y 2 frac sum x n x overline y x overline y 2 sum x n x text and sigma y 2 frac sum x,i y xi overline y 2 n , math i.e. the weighted variance of the category means divided by the variance of all samples.

The higher the lighting ratio, the higher the contrast of the image the lower the ratio, the lower the contrast. Light can be measured in footcandles . A key light of 100 footcandles and a fill light of 100 footcandles have a 1 1 ratio a ratio of one to one . A keylight of 800 footcandles and a fill light of 200 footcandles has a ratio of 4 1. The ratio can be determined in relation to F stop s since each increase in f stop is equal double the amount of light 2 to the power of the difference in f stops is equal to the first factor in the ratio. For example, a difference in two f stops between key and fill is 2 squared, or 4 1 ratio. A difference in 3 stops is 2 cubed, or an 8 1 ratio. No difference is equal to 2 to the power of 0, for a 1 1 ratio. In situations such as motion picture lighting sometimes the lighting ratio is described as key plus fill to fill alone.

The higher the ratio, the greater risk will be associated with the firm s operation. In addition, high debt to assets ratio may indicate low borrowing capacity of a firm, which in turn will lower the firm s financial flexibility. Like all financial ratios, a company s debt ratio should be compared with their industry average or other competing firms. Total liabilities divided by total assets. The debt asset ratio shows the proportion of a company s assets which are financed through debt. If the ratio is less than 0.5, most of the company s assets are financed through equity. If the ratio is greater than 0.5, most of the company s assets are financed through debt. Companies with high debt asset ratios are said to be highly leveraged, not highly liquid as stated above. A company with a high debt ratio highly leveraged could be in danger if creditors start to demand repayment of debt.

It is expressed as follows math mbox Current ratio frac mbox Current Assets mbox Current Liabilities math For example, if WXY Company s current assets are 50,000,000 and its current liabilities are 40,000,000, then its current ratio would be 50,000,000 divided by 40,000,000, which equals 1.25. It means that for every dollar the company owes in the short term it has 1.25 available in assets that can be converted to cash in the short term.

The motion ratio of a mechanism is the ratio of the displacement of the point of interest to that of another point. The most common example is in a Suspension vehicle vehicle s suspension , where it is used to describe the displacement and forces in the spring device springs and shock absorbers . The force in the spring is roughly the vertical force at the contact patch divided by the motion ratio, and the wheel rate is the spring rate divided by the motion ratio squared. This is described as the Installation Ratio in the reference. Motion Ratio is the more common term in the industry, but sometimes is used to mean the inverse of the above definition. Motion ratio in suspension of a vehicle describes the amount of shock travel for a given amount of wheel travel. Mathematically it is the ratio of shock travel and wheel travel. The amount of force transmitted to the vehicle chassis reduces with increase in motion ratio. A motion ratio close to one is desired in vehicle for better ride and comfort. One should know the desired wheel travel of the vehicle before calculating motion ratio which depends much on the type of track the vehicle will run upon. How to decide the motion ratio? It basically depends on 3 factors a Bending Moment To reduce the bending moment the strut point should be near to the wheel. b Suspension Stiffness The suspension tends to get stiff when its inclination of the shock absorber to horizontal tends to 90 deg. c Half Shafts In Rear suspension the wheel travel is constrained by the angle limitations of the universal joints of the half shafts.

When a vehicle is being driven along a road in a straight line its wheels rotate at virtually identical speeds. The vehicle s body also travels along the road at this same speed. When the driver applies the brakes in order to slow the vehicle, the speed of the wheels becomes slightly slower than the speed of the body, which is travelling along under its own inertia . This difference in speed is expressed as a percentage, and is called slip ratio . The ideal slip ratio for maximum deceleration is 10 to 30 .

unreferenced date August 2010 Selection ratio refers to the ratio of the number job positions to the number of job applicants and is used in the context of selection and recruitment . It is typically assumed to be a number between 0 and 1 where a number closer to zero implies that there are many applicants for any one position. The selection ratio provides information about the value of assessment tools, such as interviews, work samples, and psychometric tests. When the selection ratio is close to one, most applicants will need to be hired in order to fill the available positions. As such knowing that one applicant is likely to perform better than another is of limited value. In contrast when the selection ratio is closer to zero, assessment tools have greater value in indicating which subset of job applicants are likely to perform best. Estimates of the selection ratio can form part of estimates of utility for a given selection and recruitment system.
