A test in which the statistic used has a t-(Student) distribution, occurring, for instance, in the following problems.-test of the equality between the mean of a normal population and a specified value, based on the mean observed on a sample taken from this population, the variance of the population being estimated from the sample;-test of the equality between the means of two normal populations having the same variance based on the means observed on two independent samples taken from these population, the common variance being estimated from these samples;-test applying to the value of a linear regression or correlation coefficient.  1, record 3, English, - t%2Dtest

La ligne de régression, qui peut être courbe ou droite, suscite certains problèmes d'appellations; en fait, nombre d'utilisateurs et d'ouvrages spécialisés n'hésitent pas à nommer la courbe, «droite», et vice versa. Il faut également se méfier d'un faux ami, line of regression [et regression line dans son sens spécifique], ne correspond pas au générique français «ligne de régression» mais bien à DROITE DE RÉGRESSION.  1, record 4, French, - ligne%20de%20r%C3%A9gression

[In one study] the parent holding the baby apparently could see the stimuli and, therefore, potentially influence the baby's behaviour... It is essential in work of this type that both the holder and observer be "blind". Moreover, in the completed work, the test phase was designed so that recovery to novelty could not be distinguished from regression to the mean... Babies in the seven groups that the applicants propose to compare are likely to be at different phases of habituation after 12 trials. As a consequence, it would be difficult to interpret any differences in their reaction to the novel stimulus presented... Such differences could be due to differential reinforcing effectiveness of the stimulus....  1, record 5, English, - recovery%20to%20novelty

The relationship between encoding, discriminative capacities and perinatal risk status in 4 - 12-month old infants : response decrement and recovery to a novel visual stimulus was examined in [these infants]. High (HR) and low (LR) perinatal risk groups were compared to well babies. For abstract stimuli, well babies showed response decrement and recovery to novelty; LR infants revealed some decrement, but no recovery ... Using face stimuli, all groups showed decrement and recovery [Source: PASCAL database].  2, record 5, English, - recovery%20to%20novelty

The line used to describe the relationship between Y and X is generally obtained from sample data and is called the estimated regression line. It expresses the average relationship between the variable X and Y. The estimated regression line provides an estimate of the mean level of the dependent variable Y, when the value of X is specified.  1, record 9, English, - estimated%20regression%20line
