![]() A contrast is a summary of treatment means that is of interest in an experiment. The data from the experiment are used to evaluate the treatments.Īnother term for the conidence coeficient.Īn estimator that converges in probability to the true value of the estimated parameter as the sample size increases.Ī linear function of treatment means with coeficients that total zero. Central tendency is usually expressed by a measure of location such as the mean, median, or mode.Ī subset selected without replacement from a set used to determine the number of outcomes in events and sample spaces.Īn experiment in which the treatments (experimental conditions) that are to be studied are included in the experiment. The tendency of data to cluster around some value. The estimator is obtained from the posterior distribution.Ī graphical display of data in which the box contains the middle 50% of the data (the interquartile range) with the median dividing it, and the whiskers extend to the smallest and largest values (or some deined lower and upper limits). See ProbabilityĪn estimator for a parameter obtained from a Bayesian method that uses a prior distribution for the parameter along with the conditional distribution of the data given the parameter to obtain the posterior distribution of the parameter. Eficient computer algorithms have been developed for implementing all possible regressionsĪ set of rules that probabilities deined on a sample space must follow. Key Statistics Terms and definitions covered in this textbookĪ fractional factorial experiment with k factors tested in a 2 ? p fraction with all factors tested at only two levels (settings) eachĪ method of variable selection in regression that examines all possible subsets of the candidate regressor variables.
