By jim frost 65 comments. probability distributions are statistical functions that describe the likelihood of obtaining possible values that a random variable can take. in other words, the values of the variable vary based on the underlying probability distribution. suppose you draw a random sample and measure the heights of the subjects. By jim frost 1 comment. the empirical rule in statistics, also known as the 68 95 99.7 rule, states that for normal distributions, 68% of observed data points will lie inside one standard deviation of the mean, 95% will fall within two standard deviations, and 99.7% will occur within three standard deviations.

By jim frost 6 comments. the exponential distribution is a continuous probability distribution that models variables in which small values occur more frequently than higher values. small values have relatively high probabilities, which consistently decline as data values increase. statisticians use the exponential distribution to model the. By jim frost 3 comments. the weibull distribution is a continuous probability distribution that can fit an extensive range of distribution shapes. like the normal distribution, the weibull distribution describes the probabilities associated with continuous data. however, unlike the normal distribution, it can also model skewed data.

Learning statistics can be easy. my approach is to use plain english, concepts, and graphs to help you understand. it does not have to be hard! nonlinear regression model of electron mobility by density. if you’d like to know more about me, my background, and my view of statistical analysis, please read: about me. Related post: understanding probability distributions and probability fundamentals. the nuts and bolts of using z tables. using these tables to calculate probabilities requires that you understand the properties of the normal distribution. while the tables provide an answer, it might not be the answer you need. By jim frost. statistical power in a hypothesis test is the probability that the test can detect an effect that truly exists. if an effect truly exists at the population level, it’s entirely possible that a test based on a sample can fail to detect this effect. the higher the power, the more likely the test can detect a true effect.
