Statistical significance. In statistical hypothesis testing, [1][2] a result has statistical significance when a result at least as "extreme" would be very infrequent if the null hypothesis were true. [3] More precisely, a study's defined significance level, denoted by , is the probability of the study rejecting the null hypothesis, given that ...
Dog intelligence or dog cognition is the process in dogs of acquiring information and conceptual skills, and storing them in memory, retrieving, combining and comparing them, and using them in new situations. [1] Studies have shown that dogs display many behaviors associated with intelligence. They have advanced memory skills, and are able to ...
Coren's book presents a ranked list of breed intelligence, based on a survey of 208 dog obedience judges across North America. [10] When it was first published there was much media attention and commentary in terms of both pros [11] and cons. [12] Over the years, Coren's ranking of breeds and methodology have come to be accepted as a valid description of the differences among dog breeds in ...
Analysis of variance. Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means. ANOVA was developed by the statistician Ronald Fisher.

In 2012, there were 83.3 million dogs and about 47% of households had a dog. [ 48 ] 70% of the owners had only one dog, 20% of the owners had two dogs, and 10% of the owners had three or more dogs. [ 48 ] In 2017 there was an average of 1.5 pet dogs per household.
Physiological relevance is a scientific concept that refers to the applicability or significance of a particular experimental finding or biological observation in the context of normal bodily functions. This concept is often used in biomedical research, where scientists strive to design experiments that not only yield statistically significant ...
Statistical significance test: A predecessor to the statistical hypothesis test (see the Origins section). An experimental result was said to be statistically significant if a sample was sufficiently inconsistent with the (null) hypothesis. This was variously considered common sense, a pragmatic heuristic for identifying meaningful experimental ...
