How are an obervation and an inference alike and how they different?
Making observation and making inferences are both skills used by scientist. An obervation involves using the senses of sight,hearing ,smell and sometimes taste to gater info. An inference is ann interpation based on oberservation and prior knowledge
What is scientific observation?
Scientific odservation refers to a body of techniques for investigating phenomena, acquiring new knowledge or correcting and intergrating previous knowledge.In naturalistic observation, the observer does not interfere with the environment at all, and may attempt to interact with the organisms as little as possible. The observer must remain neutral, not changing anything in the environment beyond the inevitable changes which occur as a result of the presence of an observer. No experiments are conducted, and intervention is generally not allowed.Covert observation involves observation of a population without alerting the population to the presence of an observer. This technique is often preferred in animal populations, as animals may behave differently when they know that they are being watched. Covert techniques can include planting hidden recording devices and building structures for concealment which allow people to see without being seen. In overt observation, the observed is aware of the observer; in naturalistic observation of humans, for ethical reasons, only overt observation can be used.One drawback to naturalistic observation is that researchers cannot manipulate, control, predict, or even fully understand variables. This can make it difficult to test and prove hypotheses, as experimental conditions cannot be set up. Another issue which can arise is the length of time it takes to conduct research, which can be a significant barrier for some researchers. It can be difficult to obtain support and funding when a project may take decades to complete.A clear advantage to naturalistic observation is that it allows researchers to see the natural behavior of the organisms they are interested in. This can provide very valuable information which may influence future experimental research and contribute to understanding of how the organism lives in the wild. For example, naturalistic observation has been used to help conservation groups understand why some species of animals are so hard to breed in captivity, and to identify issues such as habitat restrictions which need to be considered when trying to preserve wild populations of rare species.Naturalistic observation can also sometimes be the only way to collect data about some issues. For example, experiments on humans which could subject the humans to harm or put them at risk are not allowed. However, people can use naturalistic observation to collect information about human populations which live in risky or harmful environments.
What is an unbiased observation?
An unbiased observation is one that is not affected by your bias (mental tendency/inclination or prejudice). For example, you may want to achieve a certain result, or you may only support one certain theory about your experiment. So if you are unbiased, you are looking at the results from all points of view, being realistic about what you see, and not just 'seeing' the observations because you want to or because you believe that's what you should see (this can sometimes happen unconsciously). So the results don't seem to support/coincide with one theory over another.
How can you rephrase Pasteur's quotation 'In the fields of observation chance favors only the mind that is prepared'?
Pasteur's comment, sometimes reduced to "Chance favors the prepared mind", is similar to Shakespeare's observation that "All things are ready if our minds be so."This might be rephrased as "Look carefully because you may see something you don't expect to see." This is also known as serendipity, the accidental discovery of something while trying to investigate something else. Many chemical substances and reactions were first observed during mostly unrelated experiments.(see related link)
Is coffee a homogeneous mixture or heterogeneous?
Coffee is a homogeneous mixture (assuming it has been well-stirred), as the mixture has a uniform composition throughout. Dividing the mixture into macroscopic parts, each part will have the same composition as the Save original mixture.
