Dr. Phillips is a cognitive-developmental psychologist who studies how children learn mathematical principles. His current inter

est is in studying how children learn multiplication. He recruits 54 second-graders who have not yet learned how to multiply numbers to participate in his study. He is curious as to whether different teaching styles lead to better mastery of the subject. One condition (A) involves having students read a chapter on multiplication from their textbook. One condition (B) involves having students watch a video of cartoon characters explaining multiplication. One condition (C) involves having students being taught multiplication from a teacher. One condition (D) involves having students being taught multiplication by a fourth-grader. In all conditions, participants spend 30 minutes learning the fundamentals of multiplication and are then given the same 15-question multiplication test. The number of questions answered correctly is recorded. Explain why Dr. Phillips cannot conduct a within-groups design.

Deal$ stores sell a wide variety of low-priced merchandise: party supplies, cleaning products, toys, food, housewares, and healt
Lerok [7]

Answer:

The correct answer is Demographic segmentation by Income

Explanation:

In marketing Demographic segmentation implies segmentation of the market in groups by certain factors, like for example, race, age, education, income, religion, etc... to exploit the demographics in their advantage this marketing study helps to identify where would a product or service sell more, or where is convenient to open up a business.

Now in this particular case, Deal$ stores are using income segmentation by selling products of a certain (in this case lower) price, the whole attractive of Deal$ stores is the lower price and not the quality of the products sold there, thats why income segmentation is present, because they are literally aiming at one specific kind of customer that wants really low prices.

IrinaK [193]
Madison’s outlook on the intrinsic power potentials of the three branches of government is that no branch should be more controlling than the next. Madison supposed in balancing the division of powers between the three branches, where their powers were one and the same. Madison stated that a tough and powerful government is wanted, but an inadequate government is also significant where no branch is prevailing. Due to Madison and his thought of checks and balances within the three branches of government, our government is more equipped than it was before. His plan involved getting rid of circumstances where a majority is united by a common interest, where the human rights of the minority are timid.
