Benchmark Poll voter survey carried out immediately after polling stations left. The elections are a example.
Random Sample is a subset of individuals (the sample) selected entirely at random from a larger set (the population) by a process that ensures that: All individuals in the population are equally likely to be chosen for the sample.
In a political survey the margin of error varies depending on the candidate, that is, it depends on the geographic distribution of his constituency, so it is necessary that this type of survey be carried out within a confidence interval, value agreed by the client and the research institute .
In political research the standard of the confidence interval is 95%, what does that mean? This means that the candidate has a 95% chance of being within the margin of error and 2.5% of being above it and 2.5% of being below it. For example: suppose that in an election poll a candidate appears with 23%, taking into account the margin of error of 2.5%, he will be between 20.5% and 25.5%.
Because of this margin of error, when announcing the fall or rise of a candidate, it is valuable that successive surveys are carried out, comparing only the current survey with the previous one will give an answer with the possibility of much greater error.
Focus groups are usually a group of 10 or fewer people who come together to discuss a particular topic, product or idea. Focus groups are a tool used in the advertising and market research industry and are commonly used to measure the potential impact of a product.
Part of Question completed :
Which basic principle of individual choice does Charles's plan illustrate that his wife's advice does not?
Many decisions are made on the margin.
People usually exploit opportunities to make themselves better off.
Resources are scarce.
All costs are opportunity costs.
Answer:
All costs are opportunity costs
Explanation:
All choices have opportunity costs. If Charles decides to swim, he gives up the time that he could have spent biking or running. The opportunity cost of an hour of swimming is therefore an hour of biking or running, whichever he believes has most value as an alternative which could justify the sacrifice of one hour for swimming alone. There is no information on the value of an extra hour swimming however so we cannot determine whether it is best for Charles to spend time equally on all sports or otherwise.

Answer: The correct answer is B: Generate a novel behavior.
Explanation: Shaping is a type of differential reinforcement of succesive aproximations, and the goal is for the person, (in this case a cat name Fluffy) to exhibit a target behavior (Use his paw to turn on the Tv).
Turning on the tv with his paw is not a behavior Fluffy has, so Sarah reinforce succesive aproximations until fluffy exhibits a novel behavior.
<u>In conclusion, the answer is B, in this case the shaping is used in order to generate a novel behavior. </u>
