One factor that may make it difficult to interpret the result of even a true experiment in a natural setting is contamination (when there is communication of information about the experiment between groups of participants). Briefly describe the three types of problems that can result from contamination.

Answers

Answer 1

Explanation:

Contamination can have undesirable consequences in real experiments, some of them are related to the feelings that may arise in the research participants, the contamination bias reduces the differences between the research groups, and can cause a comparison between the treatments of each different group, the which can generate conflicts and rivalries on the part of groups that consider themselves to be inferior to others. These contamination-related problems can significantly interfere with the research results.

Explanation:

Importance of statistics for evidence-based policy making

Statistics is a mathematical science involving the collection, analysis, and interpretation of data, as well as the effective communication and presentation of results relying on data. Through application of various tools and techniques in statistics, the raw data becomes meaningful and generates the information for decision making purpose. Statistics is very important when it comes to the conclusion of research. Statistical methods and analyses are often used to communicate research findings and give credibility to research findings and conclusions. It is important for the users of research to understand statistics so that they can be informed, evaluate the credibility and usefulness of information, and make appropriate decisions.  

Today, statistical methods are applied in most of the fields that involve decision making, for making accurate inferences from arranged data. Evidence-based policy has been defined as an approach which “helps people make well informed decisions about policies, programmes and projects by putting the best available evidence at the heart of policy development and implementation” (Davies, 1999). Different evidence based policies of the government are based on statistics. For instance, statistics holds a central position in fields like industry, commerce, trade, economics, biology, astronomy, etc., hence application of statistics is very wide.

The society in Europe was affected with the loss of so many people at the same time during plague. Explain.

Answers

Answer:

Explanation:

The plague killed indiscriminately young and old, rich and poor but especially in the cities and among groups who had close contact with the sick. Entire monasteries filled with friars were wiped out and Europe lost most of its doctors. In the countryside, whole villages were abandoned. The plague had huge scale social and economic effects, a lot of which are recorded in the introduction of the Decameron. People abandoned their friends and family, fled cities, and shut themselves off from the world. Funeral rites became perfunctory or stopped altogether, and work stopped being done. The Black Death was one of the most devastating epidemics in human history. It was the first outbreak of medieval plague in Europe, and it killed tens of millions of people, an estimated 30–50 percent of the European population, between 1347–1351. The long term effects of the Black Death were devastating and far reaching. Agriculture, religion, economics and even social class were affected. Plague brought an eventual end of Serfdom in Western Europe. The manorial system was already in trouble, but the Black Death assured its demise throughout much of western and central Europe by 1500. Severe depopulation and migration of the village to cities caused an acute shortage of agricultural labourers.

Answer with Explanation:

The Bubonic Plague, which was also known as "Black Death" hit Europe in the 1300s. It is said to have started from a ship that arrived with dead sailors onboard. From then on, it spread to many people killing more than 20 million of Europe's population. This event caused panic to people that they tried not to communicate with the sick and even other people. The doctors also didn't want to see those who were ill. The stores were closed and people move towards the country area in hopes of escaping from the illness. They became very desperate to survive that they left whoever was sick–even their very own loved ones.

The plague was unimaginable. Doctors tried techniques that were considered harmful such as lancing the boil. Some of them resorted to practices that were superstitious in nature.
