How Sample Size Affects Standard Error - dummies

Suppose X is the time it takes for a clerical worker to type and send one letter of recommendation, and say X has a normal distribution with mean 10.5 minutes and standard deviation 3 minutes. The bottom curve in the preceding figure shows the distribution of X, the individual times for all clerical workers in the population. According to the Empirical Rule, almost all of the values are within 3 standard deviations .

Explaining the 68-95-99.7 rule for a Normal Distribution

Jun 04, 2018 · The normal distribution is commonly associated with the 68-95-99.7 rule which you can see in the image above. 68% of the data is within 1 standard deviation (σ) of the mean (μ), 95% of the data is within 2 standard deviations (σ) of the mean (μ), and 99.7% of the data is within 3 standard deviations (σ) of the mean (μ).

The D10, D50 and D90 are commonly used to represent the midpoint and range of the particle sizes of a given sample. Particle size distributions have been traditionally calculated based on sieve analysis results, creating an S-curve of cumulative mass retained against sieve mesh size, and calculating the intercepts for 10%, 50% and 90% mass.

Normal random numbers - MATLAB normrnd

r = normrnd(mu,sigma) generates a random number from the normal distribution with mean parameter mu and standard deviation parameter sigma. r = normrnd(mu,sigma,sz1,...,szN) or r = normrnd(mu,sigma,[sz1,...,szN]) generates a sz1-by-⋯-by-szN array of normal random numbers.

Distributions: Uniform, Normal, Exponential

When λ = 1, the distribution is called the standard exponential distribution. In this case, inverting the distribution is straight-forward; e.g., -nsample = loge(1-x) nsample = -loge(1-x) which is a closed form formula for obtaining a normalized sample value (nsample) using a random probability x.

Grain-size distribution curves of the original sand (prior to shearing) and the sheared sand from the shear zone are then compared. The mechanism of particle breakage is determined by a thorough examination of particle damage under constant normal load (CNL) and constant volume (CV) tests, considering both loose and dense samples.
