Deserts to east and west. mountains in the south, and the seas on the north.
The recent occurrence of both severe and prolonged droughts as well as floods is being worsened by global climate change.
Global climate change is the rise in average surface temperatures on earth which occurs mainly as a result of human activities such as the use of fossil fuels, which discharges carbon dioxide and other greenhouse gases into the air. These gases trap heat within the atmosphere and this can have various effects on ecosystems, including droughts, rising sea levels, and very bad weather events.
Answer:
Using convenience samples to develop constructs and scales can be risky.
Explanation:
Convenience sampling refers to the process of gathering information from a sample that is conveniently available to the researcher (family members, friends in social media). This is not a random sampling method because not all of the members have the same probability to be selected.
- Using convenience samples to develop constructs and scales can be risky.
From the definition, we can say that using convenience samples to develop constructs and scales can be risky since <u>the information gathered by using this sampling does not necessarily represent the characteristics of the population (since it was not chosen at random).</u>
- It is a time-consuming process when there are a large number of respondents.
This is not a time-consuming process but is actually easier to gather information this way rather than by other methods.
- It is commonly used in the later stages of research.
This process is a gathering of information process and it takes place at early stages of the research
- The representativeness of the sample can be measured because sampling error estimates are not calculated
As we said before, this is not a random sample and therefore it is not necessarily a representative sample.
- It is commonly used to generalize results to the target population.
Although probably our sample shares some characteristics with our target population, this sampling is not used to generalize results to the target population.
Full question:
A scientist at a chemical company designs and conducts an experiment to determine if a chemical made by the company is harmful to crops. To do this, he sprays the chemical on three plants he has in the laboratory. None of the plants survive. The scientist reports that the chemical is not harmful to crops and publishes a paper stating that the chemical should be sprayed on all fields. The scientist is being
a observant
b unethical
c skeptical
d open-minded
Answer:
B. Unethical
Explanation:
In scientific experiment, Unethical action refers to actions that violate a set for moral standards/principles that is commonly held by other people in society. Usually, they do such unethical actions to obtain a personal gain by sacrificing other people.
In the example above, the scientist was fully aware that the chemical substance is dangerous (because the plants died after he sprayed the chemicals).
Despite that, that scientist chose to harmful to crops and publishes a paper stating that the chemical should be sprayed on all fields (most likely because he obtain some sort of reward from the chemical company if he show a positive research result) . This might caused a destruction to the environment and endangered the lives of a lot of people.
