Answer:
B. Display a sense of musical phrasing
Explanation:
This is a very interesting question that, depending on who reads it, the answer may change, especially because when it comes to babies there is not an absolute consensus about what is really going on in their brains. Besides, with the day to day advances in neuroscience there is always something new we understand (or realize we dont understand at all!) about the brain. In my case, I got to answer B just by aplying some logic:
A) "Prefer nonspeech over human speech". There are two main reasons why i think this cannot be the correct choice: first, when babies are around 7 months they start trying to imitate verbal communication of their parents, and, second, because it seems very unrealistic to say that a baby (4-7 months old) is actually prefering one way of speech over another.
C) "Prefer pieces of music with awkward breaks rather than those with pauses between phrases". This is an answer we can certainly put aside because of it subjective and demeaning way of expressing (i.e "awkward breaks").
D) "Listening to a foreign language rather than their native tongue". Again, two reasons, first the "preference" assumption, and secondly, assuming a baby would understand the difference between two diferent tongues is laughable.
B) Display a sense of musical phrasing. I would think this is the correct choice, not only because the other possible questions are clearly faulty, but also because I have encountered with multiple articles in which the music importance in the language and cognitive development of the baby is shown.
Hope this helps!
Federal Communications Commission (FCC) regulates the television and radio industries.
Answer: Option B
Explanation:
The Federal Communication Commissions (FCC) exercises its control over radio frequency, broadband access, the usage of media in a safe and responsible manner etc. This is a government agency set by the Government of the United State of America to regulate the television and radio industries.
This body oversees the communications happening in other North American countries like Canada and Mexico. The Federal Communication Commission was implemented to replace the previously existing Federal Radio Commission.
Answer: B) (FCC) Federal Communications Commission
Explanation:
(a) 7 mph
(b) 11 mph
(c) 18 mph
(d) 25 mph
Is the dependent variable discrete or continuous?
What scale of measurement (nominal, ordinal, interval, or ratio) is used to measure the dependent variable?
Answer:
a) dependent variable = the effectiveness of study strategies based by the number of correct answers on a test (the different study strategies used)
b) discrete: finite and countable number of questions
c) ratio scale
Explanation:
Dependent variable: The variable being tested or measured in an experiment are dependent variables. In an experiment, the researchers are measuring at how alteration in the independent variable can lead to changes in the dependent variable.
Discrete variable: In a discrete variable, variables can only take a finite number of values. It includes qualitative variables. Whereas, few quantitative variables are also present i.e performance being ranked as 1, 2, 3, and so on.
The variable consists of four levels of measurement i.e nominal, ordinal, ratio, and interval.
Ratio scale: This type of variable measurement scale is quantitative. It allows the researcher to compare the differences or intervals. It possesses a zero point of origin.
The dependent variable is the number of correct answers on the test, which is a quantitative discrete variable measured on a ratio scale because it includes a true zero point and allows for comparing differences in the number of correct answers.
In the experiment conducted by Weinstein, McDermott, and Roediger (2010), the dependent variable is the number of correct answers recorded on the test following the study session. This variable reflects the participants' performance, which is expected to depend on the type of study strategy they used (whether they generated and answered questions after reading or simply read the passage a second time).
The dependent variable in this study is quantitative discrete because it is the result of counting - the number of correct test answers can be counted in whole numbers. It does not fall into the category of continuous variables because it is not a measurement that can take on any value within a range, like height or weight.
The scale of measurement used to measure the dependent variable is the ratio scale. This scale is used because the number of correct answers has a true zero point (indicating that no questions were answered correctly), and the differences between the values are meaningful and comparable. For example, a score of 10 implies twice as many correct answers as a score of 5.
