Sprains (including anterior cruciate ligament tears) and strains also accounted for the largest proportions of injuries in competition and practice requiring ≥7 days before return to full participation, (52.1% and 47.8%, respectively) and the largest proportion of injuries requiring surgery (57.7% and 52.9%, respectively). If the numerator is the number of women (179) who attended a clinic and the denominator is all the clinic attendees (341), the proportion of clinic attendees who are women is 179 ⁄ 341, or 52% (a little more than half). It is calculated by dividing one interval- or ratio-scale variable by the other. The speedometer of a car indicates the car’s speed or rate of travel in miles or kilometers per hour.

Proportionate mortality is the proportion of deaths in a specified population during a period of time that are attributable to different causes. Between 1971 and 1975, as part of the National Health and Nutrition Examination Survey (NHANES), 7,381 persons ages 40–77 years were enrolled in a follow-up study. For example, one could calculate the proportion of persons enrolled in a study among all those eligible (“participation rate”), the proportion of children in a village vaccinated against measles, or the proportion of persons who developed illness among all passengers of a cruise ship. Sometimes students want an alternative explanation of an idea along with additional practice problems. It is used as a measure of the severity of illness: the death-to-case ratio for rabies is close to 1 (that is, almost everyone who develops rabies dies from it), whereas the death-to-case ratio for the common cold is close to 0.

In epidemiology, proportions are used most often as descriptive measures. In epidemiology, ratios are used as both descriptive measures and as analytic tools. Death-to-case ratio is the number of deaths attributed to a particular disease during a specified period divided by the number of new cases of that disease identified during the same period. As a fraction, a ratio can be treated like any other fraction. Common frequency measures are ratios, proportions, and rates. Lines ℓ and j are perpendicular.

Joy Li. Hyattsville, Maryland: National Center for Health Statistics, 2003; 9:30–3. High patient-to-nurse ratios are strongly associated with emotional exhaustion, job dissatisfaction and fatigue. For these epidemiologists, a rate describes how quickly disease occurs in a population, for example, 70 new cases of breast cancer per 1,000 women per year. This is called solving for “X” or solving for the unknown. 2015 CFA Level 1 Practice Exams-Volume 2. A short summary of this paper. If the F1 crickets were crossed to homozygous recessive crickets (i.e., DdEe x ddee) the progeny would be DdEe, Ddee, ddEe, and ddee in equal proportions -- i.e., 1/4 of the progeny will be able to see, and 3/4 will be blind. Ratios and Proportions. Proportions can easily be converted to ratios. These proportions are not rates because the denominator is all deaths, not the size of the population in which the deaths occurred. Check your answers, Geometry 7.1.
