Which period is considered to be the most sensitive for language development?
The sensitive period for spoken language is from 7 months to 3 years of age. It begins when the child first creates sounds by mimicking mouth movements, and progresses over time, as they learn to form words and simple sentences. The sensitive period for learning to write is from 3.5 to 4.5 years of age.
When a correlation coefficient of 0.80 is found between factor A and factor B the most accurate interpretation is that?
4) When a correlation coefficient of -0.80 is found between factor A and factor B, the most accurate interpretation is that A) there is a very weak relationship between the two factors. B) a decrease in factor A is strongly related to an increase in factor B.
When studies are based only on observations the results should be expressed as quizlet?
one event is strongly related to another event. When studies are based only on observations, the results should be expressed as: descriptions.
What is considered a strong correlation?
The relationship between two variables is generally considered strong when their r value is larger than 0.7. The correlation r measures the strength of the linear relationship between two quantitative variables.
Which of the following would be considered a very strong negative correlation?
A correlation coefficient of -0.8 indicates an exceptionally strong negative correlation, meaning that the two variables tend to move in opposite directions. The closer the coefficient is to -1.0, the stronger the negative relationship will be.
At what age is it easier to learn a second language?
Well, all researchers agree that the earlier a child starts learning a second language, the better, for more reasons than one. Some researchers say that second language acquisition skills peak at or before the age of 6 or 7.
What age do you stop learning languages?
They concluded that the ability to learn a new language, at least grammatically, is strongest until the age of 18 after which there is a precipitous decline. To become completely fluent, however, learning should start before the age of 10.
What is a good correlation?
Values always range between -1 (strong negative relationship) and +1 (strong positive relationship). Values at or close to zero imply a weak or no linear relationship. Correlation coefficient values less than +0.8 or greater than -0.8 are not considered significant.
Which of the correlation value is reliable?
Correlation coefficients It measures the relationship between two variables rather than the agreement between them, and is therefore commonly used to assess relative reliability or validity. A more positive correlation coefficient (closer to 1) is interpreted as greater validity or reliability.
What is the percentage of white teachers in the US?
