The process of experimentation and why science uses experimentation

Paper instructions:
Fiirst, on a separate page and in short answer format, address the following questions:
Explain the process of experimentation and why science uses experimentation.
Identify characteristics of a good experiment or experimental design.
How do scientists determine how large a sample is large enough? What factors play into this determination?
Then, referring to you answers to the questions above, complete the following:
Write a hypothesis. (Hint:Make your hypothesis something that is easily testable and which is based on an observation. The clearer your hypothesis, the easier it will be to create an experimental design. Easily testable hypotheses address a single relationship between two factors, are clear and concise, with all terms clearly defined).
Examples of easily testable hypotheses: these are just examples
If the rate of photosynthesis is positively related to temperature, then increasing temperature will increase the rate of oxygen production.
If root growth is related to gravity, then roots will always turn toward the earth regardless of a seed’s orientation.
If hatching of brine shrimp is related to salinity, then the greater the salt concentration, the higher the hatching rate.
If the thickness of annual growth rings in trees is related to annual rainfall, then examining wood samples will reveal correlations between the growth rings and past rainfall for trees in their environments.
Design an experiment to test your hypothesis. Remember you are under no obligation to actually test the experiment. So be creative but make sure the experimental design is sound (i.e. that it controls for random variables, and addresses the hypothesis specifically).
Finally, write a 2 page paper providing:
The hypothesis and prediction(s) of the hypothesis.
How, when, and where the experiment would be set up. Please justify why.
The variables you would need to control for given your hypothesis.
How large a sample size you would need.
The time you think you would need to run the experiment (elapsed time for the experiment’s results to be observable).
The type of data you would collect and how you would go about analyzing it to determine if your hypothesis would be supported. Predict what pattern you think you will see with the collected data and what conclusions you anticipate drawing from these patterns?
How many times the experiment would need to be run to generate sufficient data. Include any other information pertinent to the experiment.
Include relevant sources (i.e. similar studies to yours) supporting why you chose to design your study the way you did (i.e. the length of study, the sample size, the time frame needed to observe a given aspect of the study, etc.)

relationship between science and technology

Paper instructions:
In a 2-page short answer or short essay format, respond to the following:

What is a Critical Literature Review?
A literature review is an account of information published on a topic by scholars and researchers in scholarly journals and publications. The purpose of a literature review is to convey to your reader the knowledge and ideas, in strengths and weaknesses, established on a topic. As a piece of writing, the literature review is defined by a guiding concept–for example, your research objective, the problem or issue you are discussing, or your argumentative thesis. It is not just a descriptive list of the material available or a set of summaries.
Besides enlarging your knowledge about the topic, in writing a literature review you gain and demonstrate skills in information seeking and critical appraisal. Information seeking is the ability to scan the literature efficiently, using manual or computerized methods, and to identify a set of useful articles and books. Critical appraisal is the ability to apply principles of analysis to identify unbiased and valid studies.
A literature review must:
Be organized around and related directly to the thesis or research question you are developing.
Synthesize results into a summary of what is and is not known.
Identify areas of controversy in the literature.
Formulate questions that need further research.
Critical Literature Review Instructions
There are two goals for the course project.
The first goal is to gain in-depth knowledge of the practical use of an instrument related to your current or future occupation or area of specialization.
The second goal is to learn how to critically evaluate the use of any psychological assessment instrument.
The specific project objectives are presented below.
To successfully complete this project, you will be expected to:
Evaluate the different administration methods of an assessment instrument.
Evaluate the psychometric properties of an assessment instrument.
Apply standards and principles for assessment when using an assessment instrument.
Evaluate a psychological measure.

Project Requirements
To achieve a successful project experience and outcome, you are expected to meet the following requirements.
Specific Content Requirements
Submit a Critical Literature Review on a psychological instrument currently used in your present or future occupation or area of specialization. You may choose to further investigate one of the instruments you evaluated in Unit 3 or Unit 4. However, the reviews obtained from the Mental Measurements Yearbook cannot be used as primary sources or as article summaries. The reviews may be used for comparison purposes, and they may be included as additional references for your review.
Select and summarize 10-12 articles from scholarly or peer-reviewed journals and publications. You will find full text articles in the Capella Library’s many journal databases, such as PsycINFO, which has APA journals.

Animal Experimentation exsercise

Assignment, Agriculture
Animal Experimentation exsercise questions in assessing the efficacy of a new, untested cattle feed additive (Growit Fast)
Project description
Design an experiment in which you assess the efficacy of a new, untested cattle feed additive (Growit Fast). Following an LD50 study the EU have classified this additive under category 2 for toxicology. The manufacturers claim that when the additive is provided at optimum levels that growth performance is improved in all classes of cattle by 13%. A Literature indicates that mean growth rates (± SEM) in bulls (n=24) is 1.82 ± 0.09 kg/d and 1.34 ± 0.09 kg/d in steers (n= 24).
Word count: Not applicable. Just answer each question. Should not be more than 250 words in total for all 4 questions.
QUESTIONS:
In your answer:
a. Specify whether this study would need to be conducted under the Animals (Scientific Procedures) Act 1986 and why
b. Specify what type of experimental design you would use and why you would consider it to be the most effective and ethical
c. With your experimental design in mind calculate the numbers of animals required in your study to statistically show (i.e. P<0.05) the alleged improvement stated by the manufacturer
d. What type of statistical test would you use to analyze your data and what factors, if any, would you include in your statistical model
