Excerpt from 1975 Report of Random Sample Egg Production Tests, United States and Canada: Two-Year Combined Summary, 1973-74 and 1974-75, Range Group Rankings, 1974-75 All tests are conducted according to these basic principles. However, even the most carefully designed and conducted tests are influenced by errors of two kinds. The first kind of error is the chance deviation or unavoidable sampling error made when a small sample of eggs or chicks represents an entry; The other kind of error is due to uncontrolled or unknown environmental differences between entries that occur in spite of all efforts to treat all entries within a given test as nearly alike as possible. The differences between the results for two entries in a single test for a single year may be due to these chance variations rather than to a real difference in the performance capabilities of the two stocks. The effect of such errors in comparing stocks can be materially reduced by basing comparisons on the combined results of several tests over two or more years.
