To find the Positive Likelihood Ratio, divide sensitivity by (100 minus specificity). For the Negative Likelihood Ratio, divide (100 minus sensitivity) by specificity. Formula: Positive LR = SE ÷ (100 – SP)Negative LR = (100 – SE) ÷ SP Table of Variables Variable Meaning SE Sensitivity (%) SP Specificity (%) LR Likelihood Ratio What is…
To calculate the focal length (f), use the formula f=−R/2f = -R / 2, where RR is the radius of curvature. This formula is particularly useful for lenses and curved mirrors to determine their focal length based on the curvature. The Focal Width/Length Calculator is a practical tool for determining the focal length of lenses…
Multiply the cycling miles by 5,280, then divide by your average stride length to estimate the equivalent steps. The Cycling Miles to Steps Calculator is a handy tool for converting miles cycled into step equivalents. This conversion is particularly useful for fitness tracking, where steps are often used as a standard unit of physical activity….
To calculate Body Adiposity Index (BAI), divide your hip circumference (in centimeters) by your height (in meters) raised to the power of 1.5, then subtract 18 from the result Formula BAI = (HIP / (HEIGHT^1.5)) − 18 Variables Variable Meaning BAI Body Adiposity Index HIP Hip Circumference (cm) HEIGHT Height (m) What is a…
