बेतरतीब-नमूना इसके अंग्रेजी अर्थ का उदाहरण
If the observations can be ranked, and each observation in a pair is a random sample from a symmetric distribution, then the Wilcoxon signed-rank test is appropriate.
In frequentist terms, the parameter is fixed (cannot be considered to have a distribution of possible values) and the confidence interval is random (as it depends on the random sample).
A year later, the Boykin Spaniel Foundation did another 180-dog random sample for degenerative myelopathy, another inheritable disease which causes adult dogs to develop gradual, fatal deterioration of the spinal cord and results in death when the afflicted dogs are middle aged.
Since participants in an open-access poll are volunteers rather than a random sample, such polls represent the most interested individuals, just as in voting.
All cases who developed the outcome of interest during the follow-up are selected and compared with a random sample of the cohort.
If a test is more available to young and healthy people (for instance if people have to travel a long distance to get checked) then fewer people in the screening population will have negative outcomes than for a random sample, and the test will seem to make a positive difference.
Since the covariate is not measured for all participants, the nested case–control model is both less expensive than a full cohort analysis and more efficient than taking a simple random sample from the full cohort.
Then, they took a random sample of 428 responders and 295 nonresponders for medical record abstraction, and compared nonresponders against responders.
If the paired observations are numeric quantities (such as the actual length of the hind leg and foreleg in the Zar example), and the differences between paired observations are random samples from a single normal distribution, then the paired t-test is appropriate.
If it is possible to efficiently find random samples of a problem's solution space, as it is in the Traveling salesman problem, then it is straightforward for a randomized algorithm to find a solution that with high probability has high domination ratio: simply construct a set of samples and select the best solution from among them.
If the null hypothesis is true, that the median survival is 200 weeks, then, in a random sample approximately half the subjects should survive less than 200 weeks, and half should survive more than 200 weeks.
If people with a higher risk of a disease are more likely to be screened, for instance women with a family history of breast cancer are more likely than other women to join a mammography program, then a screening test will look worse than it really is: negative outcomes among the screened population will be higher than for a random sample.
Stephens (1987) discuss a test, based on the Anderson–Darling measure of agreement between distributions, for whether a number of random samples with possibly different sample sizes may have arisen from the same distribution, where this distribution is unspecified.
