Range divided by standard deviation
WebbChildren were divided into low-level (<−0.67 SD) and nonlow-level (≥−0.67 SD) groups based on IGF-1 standard deviation scores (IGF-1SDS). The association between IGF-1 and BMI as categorical and continuous variables was explored by Binary logistic regression, the restrictive cubic spline model, and the generalized additive model. WebbAll other calculations stay the same, including how we calculated the mean. Example: if our 5 dogs are just a sample of a bigger population of dogs, we divide by 4 instead of 5 like …

Webb19 apr. 2024 · Two standard deviations equal 2 X 10 = 20. Consequently, Chebyshev’s Theorem tells you that at least 75% of the values fall between 100 ± 20, equating to a range of 80 – 120. Conversely, no more than 25% fall outside that range. An interesting range is ± 1.41 standard deviations.
