A <u>double-blind experiment </u>allows researchers to identify the specific effects of the independent variable from the possible effects of the experimenter's and the participants' expectations about it.
<u>Explanation</u>:
The double-blind experiment is conducted to ensure that the results of the experiments are not biased. The double-blind study states that the person who is implementing the experiment and the person involved in the experiment are not aware of each other. So there will be no bias in the experimental treatment.
The reliability in the double-blind experiment is improved. Under this experiment unintentional tipping off the study participants and biasing of the evaluation results by the researchers can be avoided.
The following is missing for the question to be complete:
1. They should indicate problems may exist
2. They should answer "unknown" to any questions about plumbing
3. They should indicate that there are known plumbing problems
4. They should note the fact that it's an older system and potential buyers should have it professionally examined
Answer: 2. They should answer "unknown" to any questions about plumbing
Explanation: Since Madison had no problems with the pipes in the water system, i.e there was nothing to indicate that there was corrosion in the pipes, she simply could not know that she needed to examine the water system as a site of potential problem. As stated, the whole house is old, and substantial problems in such a house can occur everywhere. When filling in any questionnaire or form in the place provided for the plumbing system, it should be put "unknown" because there was no external sign that the pipes were corroded. Of course, even a real estate agent does not know this, and it is always possible, before purchasing a home by a new prospective buyer, to hire one of the experts to review and evaluate what may be the breakdowns and potential issues that may affect the price of the home when buying. The prospective buyer can simply consult with an expert all the items of the home where their condition is noted as "unknown".
A process that uses observation and experimentation to gain knowledge is called science. The organized set of investigation procedures which is used in science is called a scientific method. Applied science on the other hand is referred to as technology.
Answer:
The answer is working memory.
Explanation:
Working memory is a memory system which allows a person to process and manipulate information. Although it's sometimes used interchangeably with <u>short-term memory</u>, the difference is that working memory allows the person to use the information in a practical way<u>,</u> while short-term memory simply stores it. For example, a mathematical formula stored in the short-term memory will be used by working memory when solving a problem in a test.
